I. Origins
American agriculture has its origins in two separate cultural hearths. It
is a European system with a strong influences from people indigenous to
North America, who in turn based their crop patterns on plants first domesticated
in Meso-America. Colonial farming developed during the time when European
agriculture was going through a revolution and turning away from the three
field rotation pattern of medieval times.
Beginning in Roman times, Europeans practiced a rotation of three crops:
a food grain, a fodder crop, and in the third year, let the land lay fallow.
A cereal grain, normally wheat but in colder areas rye, was grown during
the first year. The grain was sown in the fall and lay dormant through the
winter. It sprouted in the spring and was harvested in the summer. After
the food grain was harvested, the fields were plowed and during the next
spring a fodder crop such as barley was planted. Barley could either be
fed to animals or brewed into beer. Because the grains were planted by broadcasting,
the fields could not be weeded. Thus, by the end of the second year weeds
were a major problem and the soil was also depleted. During the third year
the farmers plowed down the weeds and left the land unplanted for a season
to regenerate its fertility through the process of weathering the base rock
material.
Although this system persisted for centuries, it did not produce great surpluses.
The grain fields produced a harvest of 6-10 times the amount of seed sown.
Therefore, about 1/6 to 1/10 of each crop had to be preserved for the following
years' seed stock. Hunger was a constant companion of these farmers. There
was little grain to feed to animals, and so the cattle were small. Meat
was a great luxury. The milk produced in summer was preserved as cheese
and butter for consumption during the winter.
Farmers lived in villages and tilled small fields that were scattered throughout
the village's territory. This meant that most households had a mixture of
land types and no one family had all the good land. The scattered fields
also meant that a local environmental problem, such as a hailstorm, would
not destroy a family's entire crop.
This subsistence-based agricultural village produced demands for goods from
afar, and so trade was a part of the economy. Salt, spices, ironware and
other craft items were brought to the farm hamlet by traveling merchants.
In addition, there were seasonal fairs where trade and entertainment was
offered.
In some regions a seasonal grazing pattern developed which involved taking
animals to wild alpine lands to graze. In the high pastures, young animals
were fattened and milk made into cheese by shepherds and the youth of the
village.
These villages maintained ancient elements of fertility religions, which
were developed in Mesopotamia and other parts of the Mediterranean cultural
hearth. Spring was welcomed as the time of nature's rebirth. Midsummer,
a time of plenty and comfort, was celebrated with gusto. The harvest was
marked with a variety of festivities--all of which embodied some form of
thanksgiving. The winter solstice was also noted, but the deep mid-winter
was not always a time for joy and happiness.
This Roman pattern of agriculture was spread through the Empire and was
adapted to regional and local environmental conditions. In Mediterranean
climes in the summer, small grains were complemented with olive trees and
a variety of vegetables. The bounty of seafood also provided much protein.
People living in areas a distance from the seas suffered from a deficiency
of iodine in their diets because they could not easily get seafood or sea
salt.
Imperial Roman agriculture was the base for three forms of North American
agriculture--farming-mixed crop and livestock, Mediterranean, and ranching.
North American mixed crop and livestock farming is a derivative of the agriculture
practiced in the Northwestern portions of the Roman Empire. The agriculture
landscape of European three field agricultures had few structures and essentially
no fences. Barns were box-like structures which a central threshing floor
that was accessed by large sets of double doors on either side of the barn.
When the grain was being separated from the chaff, both sets of doors were
opened and the wind currents carried away the dust. The few animals had
their special structures-stables for horses, byres for cows, styes for pigs,
folds for cheep, and coops for chickens.
When North America was colonized, Northern European farmers were beginning
to use new crops and increase the importance of livestock in the economy.
The most significant new crops were turnips and clovers. The turnips were
used for animal feed and were planted in rows. The row crops can be cultivated
and therefore it was not necessary to fallow the land to control weeds.
A clover is a legume that fixes nitrogen and thereby increases the soil's
fertility. Clover can be cut as hay or grazed as pasture. In addition, clovers
require a cover crop to get it established. Clover seed and rye or barley
were planted together.
The result of these innovations was a new crop rotation system that operated
on a four-year cycle. In the first year, a bread grain crop was planted,
typically wheat. In the second year, one of a variety of root crops (turnips,
beets, potatoes) was grown. In the third year, feed grain and clover were
planted and the feed grain was harvested in the fall. The clover was either
harvested or grazed during the fourth and final year.
This change was truly revolutionary because it was no longer necessary for
farmers to leave 1/3 of their arable land idle. The new rotation produced
more winter feed for animals. The farmers practiced selective breeding and
developed larger animals. They switched from oxen to horses as draft animals.
Horses can do more work than oxen but are more expensive to maintain because
they need grain and better fodder. The increase in the number of animals
increased the manure supply. This very significant development enabled farmers
to actually improve the fertility of their fields. This increase in agricultural
capacity came at the time of urban growth and so a market was created for
surplus which encouraged additional investments and innovations.
Without the growth of urban markets, farmers would have little incentive
to increase productivity. As it was, urban merchants and members of the
gentry became fascinated with the scientific agriculture and promoted developments
in animal and plant breeding. Such ideas were discussed in papers and spread
widely.
John Frazer Hart and other scholars have established the Lancaster Plain
in Southeastern Pennsylvania as the seeds bed for the mixed crop and livestock
or "Corn Belt" agriculture of the United States. This plain is
the only extensive tract of excellent farm land on the seaboard. The land
was settled by German Mennonite farmers in the first decade of the eighteenth
century. The combination of land and people was so successful that a generation
later, the farmers invented the Conestoga Wagon to carry their bountiful
harvests to Philadelphia for export. The system was so productive that farmers
in France complained about cheap wheat imported from North America.
The colonial farmers added maize, or Indian corn, to the European crop rotation.
Corn proved to be very adaptable to the concept of crop rotation and fertilization.
It replaced the root crops in the four-year crop rotation. Soon, farmers
were growing wheat for bread, corn to feed cattle and hogs, oats for horses,
rye for the production of whiskey and vegetables and orchards of European
fruits such as apples, cherries and peaches. The indigenous American crops
of squash, potatoes and pumpkins had important roles in the gardens on these
farms. By the Revolution, 50% of the grain produced in this region was sold
for export.
After the Revolution, the growth of urban markets marked the first step
in the development of mixed crop and livestock farming--the feed lot. Farmers
in southeastern Pennsylvania began to fatten cattle produced farther west
by feeding them corn. Thus a new system was created. Wheat was still grown
for bread and cash, then corn as a fodder crop, then oats and clover--oats
for horses and clover for the cattle. The prodigious amount of manure generated
by the cattle was returned to the soil. Farms increased in productivity
and large farmers became more prosperous.
The mixed farming required different landscape features and buildings. Animals
need shelters and had to be constrained within walls, hedges or fences.
Crops needed storage facilities and there continued to be a need for a floor
for threshing wheat. Pens for feeding animals and collecting manure also
made the farm more efficient. Into this mixture was brought the Swiss barn.
This was a two-story structure with animals on the first floor and a threshing
floor on the second. It contained bins for storing grain and a fenced barnyard
or stockyard on the south side. It also contained pens for horses and cattle.
The key aspects of mixed farming--crop rotation, mixed crop and livestock
rearing, and distinctive barns--were transferred to southwestern Ohio where
they would become the norm for the agricultural heartland and the continent.
As the early immigrants passed through Pennsylvania on their way down the
great valley to the southwest, they observed the essentials of Lancaster
agriculture. The local environment of the frontier encouraged farmers to
make modifications to the system of crops and livestock. Farmers in Southwest
Virginia dropped wheat from the system and increased the roles of corn and
tobacco. They stored corn on the cob in roughly built small log barns. Later,
planks replaced logs and the ancestor of the Midwest corn crib was born.
In the poor hill country, crop rotation was replaced with the rotation of
fields, a practice called brush fallow.
In the early nineteenth century, all roads west seemed to lead to southwestern
Ohio. Three streams of immigrant farmers converged and fashioned what became
the fundamental form of modern mixed farming. From New England and New York
came farmers who specialized in wheat as a cash crop. Pennsylvanians brought
mixed crop and livestock and the use of manure. Virginians brought corn
and tobacco. These crops were grown in a rotation that featured corn rather
than wheat. Corn was planted in a field the first year. Then it was followed
by wheat or sometimes oats. The small grains were followed by clover or
alfalfa. The crops were fed to animals and which in turn were driven to
markets in the east. Hogs fit best in the system because they can digest
corn efficiently and sows produced litters of several piglets each year
so herds expand rapidly. Corn was profitable but it had its special needs.
It originated in the subtropics and needed a long growing season. It needs
fertile soil and plenty of moisture during the growing season. Therefore
the basic pattern is modified away from the core, but there is also some
variation within the central region as well. The eastern area,Ohio and east
Indiana, is an area of relatively small farms where corn is fed to hogs.
The central Corn Belt in eastern Illinois is an area of large farms that
grow grain and do not feed animals. The western Corn Belt in central Iowa
had medium-sized farms where producers grew corn and grains o feed both
hogs and cattle. To the north, the mixed crops and livestock farming of
the Corn Belt gradually changed to a pattern where corn is grown for silage
and much land was devoted to hay or pastures. To the west, where areas receive
low rainfall, small grains--especially wheat--became the dominant crop.
No animals are raised. To the south, more land is given to hay and pasture.
There are also regions that have specialized in livestock rearing, such
as the limestone basins town of northern Tennessee and Alabama. Horse and
mule raising was extremely developed here in the nineteenth century. The
lush pastures of these areas produced the prodigious numbers of animals
needed in the United States before the internal combustion engine transformed
life. Tobacco was also an early cash crop in this region and has continued
to be important.
The core areas of the Corn Belt were developed first along the rivers, where
forests were available for fuel and the waterways provided easy access to
markets. The heavy wet soils were avoided until economical ways to drain
them were developed in the mid 19th century. The railroads opened up the
prairie for corn farms and John Deere invented the self-scouring plowshare
that enabled men to break the tough prairie sod. By the 1870s, a major interregional
system of trade was developing. The farmers began to buy cattle razed in
ranches on the western plain along with their own pigs and chickens. They
grew corn for two years, then a year of oats and finally alfalfa. The fertile
prairie soils, if supplemented with manure, could produce bountiful corn
harvests. The crop rotation kept pests and weeds under control. The feed
lot industry was made possible by the railroad connection to the west and
the rapidly growing demand for meat in the industrial cities of the great
lakes shore and the north coast seaboard.
The root of the western ranches and Midwestern field lots was the southwestern
edge of the Roman Empire on the Iberian Peninsula. On the high dry plains,
cattle rearing developed along with a culture which featured low density
frontier settlement. Spanish cattle reached the Rio Grande Valley about
the time of the American Revolution, and by 1800 there were extensive herds.
The Andalusian stock was brought to the United States and mixed with French
breeds from Louisiana and those from Tennessee. The herds were usually wild
and became secure in the environment. Eventually, a recognizable Texas animal
emerged from the Mexican stock. The Texan had very long horns, light bodies,
long legs and were very self-reliant. Texans slaughtered them for their
hides and tallow. In about 1835, Texans took over the herds south of San
Antonio and learned how to handle them on horse back. Prior to the American
Civil War, there was not a significant market for these animals and for
the most part, the Texas herds grew unmolested. There were perhaps 4,800,000
head of cattle in southern Texas.
In 1879, Texas ranchers learned that their cattle could be sold in Midwestern
markets for 10 times the Texas price. All they had to do was march the animals
some 1200-1800 miles to a market. This concept was consistent with experiences
in other regions. Cattle herds from Wales were driven to markets in eastern
England. Farmers in Eastern Pennsylvania received herds from further west
about the time of the Revolution. These cattle were going to have to walk
a lot further, however.
The cattle drives got off to a slow start. The first railroad at Sedalia,
Missouri lay beyond a zone of farmers who did not welcome the herds. In
1867, J. G. McCoy solved the problem by convincing the owner of the Hannibal,
St. Joe and Kansas Pacific railroad to extend their track and build a stockyard
in Abilene, Kansas. Soon, thousands of animals were headed for the cow town
at the end of the rails. These herds were the source of stock for the Northern
ranges where hunters were removing the vast herds of buffalo.
The ranching system was made possible by the land tenure system on the high
plains. Essentially, the grass was free. The federal government owned the
land and the ranchers claimed water rights. Grazing was limited to 12 miles
from water, so the ranchers were spread out up the valleys. However, the
free range era was short lived. Barbed wire fencing was invented in Illinois
in 1874. Cheap, effective fencing involved selective breeding and allowed
farmers to secure fields. As a result, cattle ranching shifted to stocking.
Instead of raising cattle to maturity before shipping them to market, young
cattle are sold to farmers who fattened them for slaughter.
Today the ranch land still produces calves for feed lots, but there has
been another major shift. Large feed lots have been developed in well-watered
places on the plains and feed is transported to the animals instead of the
animals being transported to the sources of feed.
In between the western ranches and the corn farms of the humid Midwest lay
large wheat farms. The Wheat Belt is divided into two parts. In the northern
region, hard wheat is planted in the spring. To the south, soft wheat is
planted in the fall and harvested the next summer.
The wheat belt was developed by farmers from the eastern United States,
along with a strong mixture of immigrants directly from Northern Europe.
They came from regions where crop and livestock farming was the norm. They
arrived on the agricultural frontier at a prosperous time. Growing cities
and the lumber camps in the Grand Lake forest required an ever-expanding
supply of food. The settlement was fostered by the Homestead Act and later
sales of land granted by the federal government to railroad builders.
At first the settlers participated in subsistence farming, which soon shifted
towards the sale of wheat for a profit. Although somewhat perishable, wheat
and flour can be shipped long distances with relative ease. Mississippi
River steamboats and the growing railroad network meant that farmers could
get their harvest and markets in the east. Furthermore, in the 1850s and
during the Civil War, prices were good and improving. Although there was
a decline in prices after the Civil War, mechanization enabled farms to
remain profitable. Railroad companies encouraged farmers to settle along
their tracks. In addition, the companies laid out turns and constructed
storage facilities for holding harvests. When the wheat fever was at its
peak in eastern Minnesota, a reporter from Harper's Weekly visited the Winona
area during the harvest season. He reported that nearly everyone had wheat
on the brain and that the whole countryside was covered with a fine wheat
dust from the wheat harvest.
Wheat production raced ahead all through the 1870s and through the last
quarter of the century. In the northern sector, settlement and commercial
wheat production moved from the forested river valleys to the uplands occupied
by the Big Woods. From the forests, the wave of settlement moved on to the
long grass prairies and finally west and northwest on the short grass region
of the Red River of the north and the dry steppes beyond.
The cultivation of the northern prairie followed the removal of the vast
herds of buffalo and changes in the perception of the region in the minds
of Americans. For several years after the first traveler reports on the
region, the high plains were called the Great American Dessert. The area
was thought to both too dry and too cold for settlements. The success of
the ranching industry changed these perceptions, however, and produced concrete
evidence that it was possible for the region to not only be livable but
also productive. The federal government espoused an aggressive settlement
policy based on the Homestead Act. As settlement moved towed the dry margins
the minimum size of homesteads was increased from 160 acres to 640. In addition,
railroads were given enormous grants of land to sell off, which financed
the construction of the transcontinental routes.
Nonetheless, the government policies would have failed if entrepreneurs
had not discovered a product that could be profitability grown in the short
summers. That croup was hard spring wheat. Unlike the soft variety grown
in Kansas, Nebraska and the Ohio Valley, spring wheat can not easily be
milled with the ancient technology of mill stones. Fortunately, European
millers developed iron rollers which cracked the hard grain and passed it
through a series of rollers which produced a fine flour. When blasts of
air were directed across the flour the chaff particles were blown away a
superior white flour resulted. This technology caused a boom in the northern
plains and prairie Provinces of Canada. Because farmers were few in number
huge corporate farms called bonanza farms were opened by eastern investors.
Using migrant labor and hundreds of horses these mechanized farms produced
mountains of wheat for the mills of Minneapolis, Buffalo, New York, as well
as smaller cities.
As the farmers on the high plains were perfecting dry farming techniques
and converted the former buffalo ranges to fields, farmers in the old wheat
region shifted to the corn-hog combination that yielded higher market prices
than wheat.
King Wheat, as its was called in the
nineteenth century, proved to a be an excellent frontier crop. As the agriculture
settlement process matured, wheat was replaced by more profitable crops
everywhere by the Great Plains. Here farmers specialized with vengeance.
At first oats were grown, in addition to wheat, to be used as feed for the
horses and mules needed to run the planting, harvesting and threshing machines.
However, farmers turned quickly to steam engines and then to internal combustion
engines as more efficient alternatives to the expensive horses.
From it earliest years, wheat farming
was a global business. Once established, the bonanza farms and the smaller
successors could each out-produce regional and national consumption rates.
Minneapolis millers sent salesmen to Europe to convince bakers that north
American wheat was both cheap and high quality. Entrepreneurs in Battle
Creek, Michigan, Red Wing, Minnesota and Minneapolis went even further.
They invented exciting new ways to eat wheat and oats for breakfast. Soon
Wheaties--Breakfast of Champions--Cheerios, Shredded Wheat and Puffed Wheat
were filling store shelves and the stomachs of growing children.
Early years on the plains corresponded
to a period of high rainfall. This prompted observers to postulate that
rain somehow was increased by cultivation. Unfortunately, normal dry weathers
returned and those farmers not well versed in dry land farming techniques
were forced out. In the 1930s a major drought turned large areas of the
central and southern plains into a "Dust Bowl" and people left
the area. Many families packed up and drove west to California where they
worked as migrant laborers on fruit and vegetable farms. Settlement on the
wheat frontier has waned ever since.
By 1920, most wheat growing counties
reached their peak population. Great storage elevators dominated the small
towns, and during War time the small towns prospered. Grain marketing and
milling firms connected the isolated farmsteads and small towns to markets
and consumers around the world. The mutual dependent relationships among
farmers, millers and shippers produced large profits and a great deal of
tension. Soon political pressure from farmers forced the states to establish
rules and regulations to govern the shipping and storing of grain. For example,
many states established State Railroad and Warehouse Commissions to monitor
the process of getting the grain to markets.
The increased mechanization of wheat
production decreased the size of the labor force needed for farming. In
addition, farmers realized they needed vast acreage to achieve a return
on their investments in machinery and seed. Thus large farmers became the
norm. As elderly farmers retired they either sold or leased their land to
neighbors. Because the grain farms had no animals, farmers did not need
to live on the land during the winter. For a time, terms like "sidewalk"
or "suitcase" farmers were used to describe the migratory farmers.
Farmers lead an urban or industrialized life style. Large machines applied
seed, fertilizer, pesticides and herbicides to the land. Seed and chemicals
were bought from large cooperatives of corporations. Market reports came
from cities hundreds of miles distant from the farmers via computers or
radio.
By the 1960s North American Farmers
produced huge surpluses of wheat and other grains. In order to help the
rural culture of the United States survive, the National Government developed
a system of price supports and other payments to farmers. For the most part,
these program did not achieve the goal of keeping the population in the
countryside. For a time, sales of wheat to the Soviet Union buoyed the wheat
regions. President Jimmy Carter's decision to halt grain sales to the USSR
caused a dramatic decline the demand for American wheat. As a result, growers
in other parts of the world increased grain production and fulfilled the
Soviet orders. More recently, declines in the prosperity of Asian nations
during the 1990s have also affected the demand for wheat. The decreased
demand and good harvests around the world have made it nearly impossible
for wheat farms in the United State to make a profit. As a result, the number
of full time farmers in North & South Dakota, Nebraska and Kansas declined
18-20% between 1980 and 2000.
Because farmers do not rotate crops
when growing wheat, diseases, weeds and insect pests are major concerns
and must be controlled chemically. Wheat is especially vulnerable to a fungus
called rust, which reduces production of each plant. A complete support
system has been developed to help farmers control rust and other diseases.
At public universities the states maintain extensive research programs of
applied research in plant genetics, botany and chemistry. Private corporations
provide a plethora of agriculture chemicals and in then carry on extensive
research programs. In addition, state governments support extension agents
that reach out to the agriculturists with a wide variety of services. The
combination of public and private support produced what is called the Green
Revolution in wheat growing regions outside the United States. Its impact
on North American farming has been incremental. Yields have steadily increased
and farmers become more productive each year. However, North American farmers
must become even more productive to compete against lower-cost wheat elsewhere
in the world market.
Formerly, wheat growers put aside a
fraction of their harvest to be used as seed for the coming year. Today
seed is bought in town and is just one of the engineered inputs of modern
agriculture. New strains of wheat are developed to match specific environmental
constraints and herbicides. The new seed requires fertilization and production
from pests and so both insecticides and herbicides are also purchased and
applied. All these purchased inputs require wheat farmers to carry large
debts. Some farmers in the Red River Valley of The North spend about $225,000
each spring just to plant their crops. As might be expected, credit is an
integral part of farming. The case flow on debt and production puts great
pressure on individuals and families during times when prices are bad or
harvests poor. In 1997, prices for a bushel of wheat reached $2.06, the
same price a bushel brought in 1866. It is possible that another 20-25%
of full time grain farmers will go out of business as the century comes
to an end.
The monoculture wheat country has few towns of great size and the urban
system established by the early railroad developers has collapsed. A line
of grain elevators is all that remains of many farm service centers. The
populations of the towns in the region are elderly and most observers predict
a further decline of population in the land of King Wheat.
The distribution of wheat growing regions
of the world corresponds well to the model of land use develop by Von Thunen.
They lie between the more intensive mixed farming regions and the more extensive
cattle ranching county. In the model, location is based on transportation
costs, and wheat products can be shipped fairly easily. These are not the
best environments for wheat production, but other more profitable crops
have replaced wheat in the better watered areas closer to the markets.
Dairying
Dairying is another form of agriculture that developed from mixed crop and
livestock farming. During the subsistence period nearly all farmers kept
cows. They were the household's source of milk, butter, and cheese and meat.
However dairy cows were not as profitable as other animals or crops. The
difficulty of shipping fluid milk in the nineteenth century meant the farm
surplus production had to be converted to butter and cheese or used to fatten
pigs. With the advent of trains and later good highways, it became possible
to profitably ship milk scores of miles to urban markets.
The growth of large urban markets created a potential demand for milk and
farmers on the old margins of the corn belt began to specialize in milk
production. The location of dairy farms is generally around large cities
and between the prime hog-corn-soybean farms of the corn belt and the big
woods. In the 1920s nearly every family in this region had a cow, but by
1990 dairying was concentrated in a much smaller region consisting of eastern
Minnesota, Wisconsin and up-state New York. Cows have all but disappeared
from the prime land in the central corn region of Iowa, Illinois, Indiana
and Ohio. Another large population of cows lives near the metro areas of
the southwest. In fact California ranks first in the total number of cows.
Apparently, there was some resistance among corn-hog farmers to the rearing
of cows. However, the newer immigrants from Europe had to settle on the
cheaper and unoccupied lands of New York and the Great Lake states. They
brought to the Untied Stated breeds of dairy cattle from the shores of the
North Sea with names liked Holstein -Frisian, Guernsey, Jersey, Ayrshire
. These were joined by Brown Swiss, Red Devon and the milking Shorthorns.
Each of these breeds had distinctive characteristics. Some like the Guernsey
and Jersey produced a rich milk high in butter fat. Others like Holsteins
produce large quantities of milk. At first farmers preferred breeds like
the Devon Reds, Dutch Belted or Shorthorns that could be raised for both
milk and beef. However, as the farms began to specialize, the familiar black
and white Holstein-Frisian breed became dominate because it out-produced
the other breeds.
Cows were comfortable grazing the poor pastures of the hills and wetlands
of the poorly drained Great Lake States. Their digestive systems enabled
them to live on nearly any kinds of vegetation. However, when they are feed
grain in rations they are capable of producing great quantities of milk.
Farmers soon learned that corn, cut green and chopped, could be stored in
cylinder structures called silos where hay and corn can ferment and become
silage. This enabled the farms to feed the animals over the winter.
Of all the forms of farming, dairying demands the most time. Cows must be
milked at least twice a day. Thus, dairy farmers must live close to the
animals. The northern European immigrants settled on small farms and established
cooperative creameries to market their product. Some also maintained routes
in near by cities where they delivered to the doorsteps of their customers.
After World War Two, the milk routes were consolidated into large retailing
companies that were able to economically meet the requirements for pasteurized
milk. Eventually, the convenience stores become the primary milk sales points.
In this same period the industry began to mechanize. Milking machines, automatic
barn cleaners and tank trucks greatly increased the farmers' productivity.
On a modern farm, dairy cows are milked by machines. The milk is then cooled
and piped into a waiting tank truck trailer. The creamery delivers a clean
and empty trailer every third day and hauls away the full one. The Experiment
stations and Colleges of Agriculture in the Great Lakes States lead to new
ideas on feeds and disease control. Selective breeding produced cows who
could produce astounding amounts of milk. Average annual milk yield from
cows in 1949 was about 6,000 pounds . In 1980 it had more than doubled to
12,300 pounds. During this period the average herd size doubled to 40 head.
By the end of the century, herds reached sizes inconceivable to farmers
of just a generation ago. Farms milking 1000 cows are said to be the ideal
size. It was discovered that the more frequently cows are milked the more
productive they become. As a result, the large dairy operations have three
shifts per day and three milkings per day. Cows are housed in large structures
without stalls and eat their fill of carefully balanced rations. When they
are tired they lay down on special bedding materials. They all wear computer
chips which help the farmers monitor their health and productivity.
The drive for even greater volumes of milk has greatly favored the large
Holstein breeds over all others. However, some farms have discovered special
or niche markets that prefer the richer milk of the Jerseys and Guernseys.
The dual-purpose stock have essentially disappeared from working farms but
still exist on few farms as special interest animals.
Like wheat growing, the dairy industry has advertised vigorously to promote
their commodity. School milk programs underwritten by the federal government
and direct price supports help maintain profit margins in the face of a
decline in per capita fluid milk consumption. In 1960, per capita consumption
was 26 gallons per year. But by 1984 it stood at 22 gallons/yr. Cheese consumption
increased from 12- 18 pounds a year. Americans just love pizza.
As the average size of dairy herds continues to rise, the issues confronting
farmers have changed. Cows produce milk to feed their calves. Therefore
cows must give birth each year to remain fresh. Cows are impregnated artificially
with seaman provided by specialized genic firms that maintain a herd of
sires whose genes contain desired qualities. Farmers have always replenished
their herds with the annual calf crop. However, now large operations "farm
out" their calves to part-time farmers who raise the heifers until
they are mature. The bull calves are sold to others where they are raised
and fattened for beef. In only a few parts of the country are calves sold
for veal. This system of dispersion of the young cattle reduces the major
problem of large farms--manure disposal.
The mixed crop and livestock farms developed in Europe and the United States
have been successful because the manure produced by animals can be spread
on the fields, which replenishes the soil's fertility. However, the large
concentration of animals calls for elaborate manure management practices.
The barnyard manure piles that were found on every farm as late as the 1950s
have disappeared. It was said that one could tell the wealth of a farmer
by the size of the manure pile. Today lagoons with impervious linings receive
the liquified manure from the cattle barns. As bacteria break down the organic
matter, the remaining liquid is applied to the fields in a regular fashion.
In some cases large dairy farmers have agreements with neighboring grain
farmers to take the fertilizer.
Because of the hydrogen dioxide emissions from lagoons, the large farms
are monitored by pollution control agencies and must be sure that their
lagoons do not exceed ambient air quality standards. This situation produces
a location problem. The farms must be close enough to towns to be able to
hire the large number of shift workers needed to operate the milking parlors
but not so close that the odors offend the non-farm neighbors. As more urban
people move into the countryside, odor issues become contentious.
Poultry Production
In the 1930s, feed dealers in the south realized that they might be able
to expand their business by providing farmers with newly hatched chicks
as well as feed on credit. The farmers would be able to repay the loans
when the birds were sold. Until this time, most farmers across the United
States had a small barnyard flock of chickens that survived by scavenging
and getting handouts from the farmer's wife, who usually had responsibility
for the birds and took the profits from selling eggs in the town. The birds
were harvested for meat at the end of their useful life as layers, and chicken
was reserved for a Sunday dinner. Now, however, the mass production of chickens,
called broilers, has so revolutionized the production of chickens that chicken
is now the cheapest meat in the United States and the most commonly consumed.
Today, chickens are produced in the following way. Large agribusiness companies
operate hatcheries, feed-mills and processing plants. Day-old chicks are
delivered to the farmers, who are responsible for building a house and maintaining
proper temperature and water for the bird. The company's employees fill
the feed bins for the farmer once per week. According to the production
schedule, these employees return to collect market-ready birds and take
them away for processing and marketing. The farmer is paid a guaranteed
price for the bird.
Over the years, selective breeding has produced a very efficient chicken.
In 1940 it took about 17 pounds of feed and about 15 weeks to produce a
four-pound broiler. Forty years later it took only eight pounds of feed
and 7 to 8 weeks to produce the same size bird. In that same forty years
the size of the poultry operations increased dramatically. In 1940, broiler
houses that contained 1500 birds were considered to be large. But now contemporary
broiler houses hold 20,000 birds or more. In addition, mechanization of
water and feeding operation has reduced labor requirements from about 250
hours per thousand birds in 1940 to fewer that 25 hours. Broiler production
is an attractive option for small farmers because it requires a few hours
of non-strenuous labor each day, and then they are able work another job
off of the farm.
Broiler production is highly concentrated in intensely specialized areas
that are widely scattered in the southeastern portion of the United States.
The modern broiler industry developed on the eastern seaboard before World
War II. It then grew rapidly in northeastern Georgia and northwestern Arkansas
immediately after the War. Subsequently, concentrations developed in central
Mississippi, northeastern and northwestern Georgia and the Piedmont areas
of North Carolina and the Shannendoa Valley area of Virginia.
Many people believe that the broiler production process is really manufacturing
rather than farming because it is not directly connected to the land. The
area that produces large numbers of chickens are districts which have a
feed deficit. The feed consumed by the birds has to be shipped in from the
Midwest. The long, low one- story broiler houses are essentially factories
that use birds as machines to convert raw materials of corn and soybeans
into a finished product--meat for human consumption.
Chickens are also efficient producers of manure, and one of the major issues
of broiler production has been the disposal of the manure. While ideally
it should be returned to the land because it is excellent fertilizer, manure
is frequently feed back to the animals. The manure is rich in protein and
after it has been dried and flavored with molasses it looks like soy bean
meal and can be fed to either chickens or cattle.
Pork Production
Another major change in the traditional mixed livestock and crop farming
of North America has been the change in the production of pork. The last
decade has seen a dramatic change in the distribution of hogs. In addition
to Northern Iowa and Southern Minnesota, pork production occurs in intense
concentrations widely scattered in an area that is on the fringe of the
most productive region in North America. One center is in North Carolina,
the other in Texas and Oklahoma. In 1997, one county alone in Oklahoma produced
2 million hogs. It was the center of an area that produced 4 million hogs,
or four percent of the national total, and one-seventh of what the whole
state of Iowa produced.
These hog farms are significantly different than the traditional farms of
the Midwest. They look more like chicken or turkey ranches than traditional
farms. Each farm has long, low metal buildings in rows on dry ground and
they tend to be located in the corners of large fields. The larger area
of the field is under a center- pivot irrigation system that creates a large
circle of crop land. The corners not reached by irrigation have been converted
to sites for hog barns. The hog manure is flushed from these houses into
a lagoon where the solids settle, the liquid evaporates and bacteria breakdown
the fecal material. At appropriate times the liquid in the lagoon is pumped
through the center-pivot irrigation system and put back on the land. A hog
produces about four times the manure as an adult human, so waste disposal
issues are significant.
These farmers work on contracts and are receiving 14-day old piglets, weighing
about a dozen pounds, from large agribusinesses. The piglets are then held
on the farms in various pens until they reach about 275 pounds and are approximately
6 months old. They then go off to a processing plant. The scale of these
operations is enormous. Farmers contract with processors to deliver between
300,000 and 500,000 hogs per year.
Pork production is vertically integrated. Processors have built slaughterhouses
in these production regions that can handle around one thousand hogs per
hour. Therefore, without stretching the system, about 2 million hogs a year
can be produced. Corporations such as Seaboard Corporation Inc. dominate
the pork production region in Oklahoma. Seaboard is a diversified international
food producing company which has operations throughout the world raising
shrimp and fish and marketing various kinds of grain. The Oklahoma Panhandle
is able to engage in this intensive hog production because of the large
amount of groundwater they take from the Ogallala Aquifer. Irrigation water
is inexpensive and the natural gas used to pump it is also cheap. The local
farmers are able to produce good crops of feed grain such as corn and sorghum
to use as part of the ration for the hogs.
According to U.S. government figures, in 1997 the highest ranking counties
in terms of the value of hogs and pigs sold was Samson County in North Carolina
with $511,000, Upland North Carolina with $510,000, Texas County, Oklahoma
with $199,000, Vladen with $183,000, and Souix County, Iowa with $172,000.
individual counties aside, most of the concentration of pork is still within
the traditional corn belt with Iowa ranked number one in 1997, Minnesota
three, Illinois four and Missouri five, Indiana six. However, Oklahoma rose
from the twenty-fifth ranking state to the ninth ranking state and Illinois
dropped from the second rank to the fourth ranked. If we look at numbers
of animals, in 1997 there were 61 million hogs in the United States. Of
that 61 million, 58 million were in 20 states and 14 million were in Iowa,
9 million in North Carolina, 5 million in Minnesota, 4 million in Illinois,
and 3 million in Indiana. Oklahoma went from having 260,000 in 1992 to 1,689,000
going from the 24th to the 9th ranking state in the number of hogs. It is even more
spectacular when we look at Texas County. Oklahoma which had 13,000 hogs
in 1992 and 19,000 in 1997.
In response to these large-scale pork palaces in North Carolina and in Oklahoma,
traditional pork producers in the corn belt have had to change their ways
of production. Gone are the days of small hog feedlots on farms that were
engaged in a variety of crop production activities. Today the Midwest is
also changing itself into a pork factory operation with contracting. In
the Midwest, companies like Hormel Foods, Cargill Inc., and Land 'O Lakes,
a farmer cooperative, participate in pork production in all forms. These
companies have pig breeding farms, they supply the young pigs to the farmers
and then provide feed as well as veterinarian service. They then guarantee
the farmer a price for the pork if the farmers are raising the hogs according
to the instructions of the company. This enables the farmers to have access
to the most highly developed breeds of hogs and market their hogs without
worrying about fluctuations in the price of pork. In turn, this enables
the corporations to have a ready market for their grain. A typical family
operated farm in Minnesota would have about 4,000 pigs on the farm at any
given time.
The biotechnologic revolution has begun to impact pork production but the
future applications are even more amazing. For example, in 1999 researchers
at Baylor University reported their research had developed a way to stimulate
the pig's pituitary gland with a synthetic chemical which is inserted into
a biodegradable piece of DNA. The material is injected into a the leg of
a two week old piglet. The injected pigs grow rapidly in response to the
active gland. The treated pigs are ready for slaughter two weeks early,
they eat 35% less feed and produce less manure. All these features will
dramatically lower the cost of the finished meat. This treatment, like all
other biotechnologic practices must be approved by the U.S. Food and Drug
Administration before they can be adopted by farmers.
Changes in Grain
The mixed crop and livestock core region has also undergone significant
changes in its spatial organization and the distribution of concentrated
areas of special types of agriculture. Like the marginal variations of grain
and dairy farming, grain production has become increasing mechanized, industrialized
and specialized. The development of hybrid seeds in the 1930s was a major
break with traditional planting techniques. The hybrids developed by companies
like Pioneer, DeKalb, Cargill and others guaranteed farmers increased yield,
and standardized ear size and height of corn. In addition, breeds of corn
that could ripen faster were promulgated. The seeds were so good that the
hybrid corn was grown through out the Eastern United States by 1948, a decade
after it was first adopted in eastern Iowa and western Illinois. Had World
War II not intervened, the diffusion may have taken even less time.
The new seeds required high quality fertilizer to be successful, and herbicides
and pesticides to insure maximum yield per acre. Genetic engineers have
produced strains of seeds that are resistant to damage by herbicides and
expect to make corn that will actually fix nitrogen in the soil. The seeds
produced during the war are patented and the knowledge of their design is
the intellectual property of the companies that produce it. Farmers can
not hold back a portion of a harvest to re-plant the next year.
Store-bought seed is only one of the changes. Draft horses disappeared from
all but a few hobby farms by the late 1950s. Their place has been taken
by the tractors and self-propelled machines of ever increasing size. The
powerful new machines pull plows that cut sixteen furrows at a pass. Self-propelled
combines, with air conditioned cabs and seats designed to be occupied 8-12
hours per day, cut the stalks, shell the grain from the head, and return
the vegetable materials to the field to control erosion. These expensive
machines have been complimented by geographic information systems. Detail
maps of soil quality in individual fields are connected to global positioning
systems in the machine. This enables the farmer to vary the amounts of fertilizer
and other chemicals to match environmental conditions for every three meter
square area. This not only increases the productivity of soil, but it eliminates
over-application of chemicals. One leading corporate agronomist boasts that
with today's farming practices and existing genetic knowledge a variety
of super corn could be developed. If this super corn were to be planted,
the state of Iowa could grow a crop equal to the entire 1998 corn harvest
of the United States. He was quick to point out that such a seed, if available,
would mean thousands of farms with less fertile soil would be driven out
of business and vast acreage would be idle. Nonetheless, recent technological
advances provide vast possibilities for the future of crop farming.
The basic crop rotation in the Untied State corn belt also changed during
the last half of the twentieth century. Soybeans were introduced as a secondary
crop after George Washington Carver discovered that the bean broke down
into a rich source of oil and protien. By 1940, 5 million acres yielded
78 million bushels of beans and the United States became a net exporter
of soybeans. Production leapt ahead, and by the early 1950s the United States
overtook China as the world's leading producer. The soy meal is a very efficient
food for animals, and the oil is the most common edible oil in the world.
The market seems to have great potential for growth, as new products seem
to be continually appearing.
By the 1960s, farmers realized they could improve their income and quality
of life by focusing time and energy on crops alone, and so the farming industry
shifted away from traditional rotation. Corn was still the primary crop,
but soybeans were substituted for the small grain and hay crops. The new
combination enabled farmers to shift away from feeding their corn to hogs
or cattle. This was possible because the beans fix nitrogen and could be
substituted for both the hay and the small grain crop. Furthermore, they
were easy to grow. Farmers could use the same machines for planting and
harvesting both corn and beans, and the crops are planted and harvested
at different times. Although beans are primarily used for animal feed and
oil, producers are developing additional markets. For example, 30% of United
States newspapers use soy ink, and soybean oil is considered a viable alternative
to petroleum-based diesel fuel.
Alaska's Matanuska Valley: The Northern-Most Crop and Livestock Farming
The last great trek by farm families in the United States occurred in 1935.
About one thousand people from the relief roles in Michigan, Minnesota and
Wisconsin traveled to the Matanuska Valley in Alaska to begin an agricultural
colony sponsored by the Alaska Rural Rehabilitation Corporation. ARPC is
a non-profit corporation that was established and originally directed by
the Department of the Interior and the Federal Emergency Relief Administration.
The Matanuska Valley, about 40 miles from Anchorage, was homesteaded by
a 400 settlers between 1914 and 1916 but only 76 remained on the land when
the colonists arrived. Although the summers were short, the long hours of
daylight enabled hay and vegetables to flourish. In fact, the valley was
soon famous for gigantic vegetables, such as the 61-pound cabbage harvested
in 1957.
The pioneers that came to Alaska were the result of a colonization plan
promulgated in 1927 by the leaders of the Alaska Railroad. The railroaders
wanted to create a market in the valley. The U.S. government became interested
in the plan because there was an agreement with Canada, Japan and the Soviet
Union that military bases would not be established in the Territory if there
was prior agricultural settlement. So, at the height of the New Deal, this
a place was created. It involved selecting young couples who were accustomed
to farm work and were on the Relief Roles, and giving them a chance for
free land, animals and equipment if they would relocate to Alaska. The first
train of new homesteaders left St. Paul with great fanfare in April, 1935.
The group was given a huge reception in San Francisco and a rousing send
off when their ship left for Alaska on May first. A week later, the group
moved into a tent camp in Palmer, Alaska. Later that month the families
drew lots for 40 acre parcels. The size of the land grants is significant.
The valley is not large and the farmers were expected to engage in intensive
agriculture producing crops for the Anchorage market.
Using heavy equipment and working cooperatively, the settlers cleared their
land and began to grow garden crops. Later, using animals allocated by the
Corporations, they began to produce fresh milk and eggs, which were marketed
through their Coop. Vegetables and hay were the primary crops. The settlers
built scaled-down versions of Midwestern barns and established a lifestyle
that resembled the dairy and mixed farming/forestry operations of the Great
Lakes forest region. Life in the colony was not attractive to all the pioneers,
however, and by 1941 fifty percent of the original settlers left the valley.
Those who remained organized life around the Cooperative movement they knew
from the Midwest, and their farms provided a steady flow of food for the
nearby markets. They became famous for large vegetables. In 1957, a prize
was awarded to a farmer who grew a head of cabbage that weighed 61 lbs.
However, the colony could not compete with the jobs provided in Alaska's
other industries. While a few dairies are in operation, the musk oxen farm
is most prominent in the valley. The towns of the colonists are still flourishing
and the memory of the colonists is a key part of the local culture. But
agriculture has not proven to be a major component of the state's economy.
In 1992 there were about 250 farms in the state and the number has been
declining constantly. Less than half of the farms have an annual sales of
more than $10,000 per year. Most of current farm production is nursery and
greenhouse crops.
California and the Pacific Northwest
The third root of American agriculture is known as Mediterranean agriculture,
which originated on the shores of that sea. The Mediterranean crop and animal
combination predominates in California, where it is extremely productive.
Agriculturists in California have added to the classic Mediterranean patterns
the modified farming practices from the Midwest, such as dairying and livestock
feeding. But the basic structure can be considered Mediterranean.
The areas around the world in which Mediterranean agriculture is found share
a similar physical environment. They all border a sea and are found on coasts
where prevailing sea winds provide moisture and moderate the winter temperatures.
Summers are hot and dry, but the sea breezes moderate the extreme temperatures.
In most areas, the land is hilly or mountainous with steep slopes which
occasionally plunge into the sea or leave a small coastal plain. The rivers
are short (with the exception of the Nile!), but water is contained in erosion
features called alluvial fans that form at the feet of mountains. Ground
water stored in the fans can be reached by wells and will provide a steady
supply of irrigation water.
In this system, little farm income is earned from animal rearing. Livestock do not flourish because there is limited surface water and poor grazing. In former times, transhumance was common. Sheep and goats were moved from their winter quarters along the coast to higher pastures in the hot, dry summers. At higher elevations the animals could find enough food to support themselves. With the onset of winter, the flocks would return to the lowland and the surplus animals that cold not be wintered were slaughtered.
Crops in the Mediterranean complex are used primarily for human consumption. This sort of agriculture is frequently called horticulture, the term used to refer to the growing of fruit, vegetables and flowers. This term is not completly appropriate because Mediterranean agriculture also includes the growing of grains, especially wheat. Nonetheless, most of the world's grapes, vegetables, nuts, olives and flowers are grown in the zones of Mediterranean agriculture.
On the European and North African Coasts of the Mediterranean Sea, olives
and grapes are the most important cash crops. Two thirds of the world's
wine crop is produced in this area. Italy, France and Spain are the leading
producers, but Algeria is also extremely important. The other areas of Mediterranean
agriculture--South Africa, Chile, Australia and especially California--produce
most of the remaining one third. The growing of wine grapes is greatly influenced
by culture. Islamic farmers produce no wine even though their neighbors
lead the world in production. Likewise, immigrants from Italy established
the viticulture of California. Their names--Mondovi, Rossi--are synonymous
with Californian wines. Grapes are typically grown on hillsides to take
advantage of exposure to the sun and other micro-climatic effects. Although
grapes are very sensitive to micro-environmental a conditions to the point
where wine have tastes specific to particular vineyards, they do not demand
especially fertile soil. Thus, the thin soils on hillsides can be quite
productive. Although olive groves are dominate features of the Mediterranean
agricultural regions, they have been replaced in California with more valuable
fruit and nut orchards.
California's agriculture also differs from the classic Mediterranean type in the amount of grain grown. About half the total arable land enclosing the Mediterranean Sea is planted with wheat, which is primarily used for making pasta and bread. There, the wheat is planted in the fall and harvested the next summer. Much of the wheat land is left fallow for a year or two to recharge the soil moisture. The version of Mediterranean agriculture that dominates California's Central Valley, the southern most basins, and the coastal valleys is more intensive. More land is irrigated, less wheat is grown and more land is devoted the production of fruit and vegetables. In fact, California produces most of the nuts, citrus fruits and other fruit consumed in the United states. These crops demand great numbers of seasonal workers, and so migrant labor is an important part of the State's culture. Over the past decades, farmers have continually invested in mechanization to reduce the number of laborers employed. Nonetheless, in the prime agricultural counties over 90% of the farms use seasonal labor.
The enormous amount of agricultural production in California was made possible
by the development of transcontinental railroads and refrigerated truck.
As the transportation system improved, California production and marketing
corporations were able to tap into huge winter markets for fresh fruits,
vegetables and fruit juice concentrates. In addition, corporations like
Del Monte established large canneries to receive the valley's produce and
ship it to even more distant markets. The cost of national marketing and
distribution systems made it difficult for small operations to succeed.
As a result, the vast majority of Californian farms are operated by partnerships
or corporations.
Farming in California is complicated by the rapidly expanding urban areas.
Suburban and ex-urban developments put pressure on farmers in all the agricultural
counties. The pressure is especially strong in the most attractive areas.
Landowners in the wine growing region of the Napa and Sonoma Valleys are
facing great pressure to develop their fields and hillsides for housing.
In order to find enough land, many farmers have expanded into arid regions
and therefore must irrigate intensively. Cheap water and power have enabled
this expansion. But as the urban population grows, water for agriculture
will become more expensive. But for the foreseeable future, California will
be a dominate state in American agriculture.
California's competition in the market for horticultural crops is found
in the Rio Grand valley, the high oases of Colorado and the Southeastern
Seaboard, especially Florida. Like California, agriculture in Florida is
a corporate affair. The southeast area of commercial gardening and fruit
farming provides food for the large markets on the east coast. It is based
on mixed farming practices, spun off from he large poultry and pork operations.
The farmers use migrant labor but are also mechanizing as fast as they can
in order to reduce costs. Although some of these crops are sold fresh in
nearby cities, most are either canned or frozen. The affluent East Coast
population has created an ever-increasing demand for higher priced speciality
crops, which these farms are happy to sell. Some small dairy farmers are
shifting to speciality crops as the profits from milk decline. Their smaller
farms close to the cities are ideal locations for this type of agriculture.
Hawaiian agriculture is also dominated by corporate farms. The American
colonial families established pineapple plantations and ranches on the island
and nearly swept away the indigenous Hawaiian agriculture pattern. Plantation
is a form of agriculture that is typically found in the tropics and subtropics.
It is characterized by marked ethnic contrasts between the workers and the
owners or managers of the operation. Plantations produce crops for distant
markets and must commonly import food for the work force. They are large
scale operations that are usually devoted to one or two crops. In Hawaii,
those crops were sugar and pineapple. As is the case with most plantations,
the managers of the Hawaii apparitions imported laborers because the local
population was to small to provide enough cheep labor. The great distance
between Hawaii and its markets meant that products had to be processed on
the islands. As the labor demands of the plantations decreased, immigrant
workers moved into to other forms of subsistence and commercial agriculture.
Two types have become important; coffee and fresh flowers or green plants.
Kona coffee is the only kind grown in the United States. It is grown in
a very small region on tiny farms. The availability of frequent flights
to the Mainland and Japan enables florists to ship exotic tropical blooms
and green plants to eager consumers.
The Future of Farming in the United States.
Each year the number of farms in the United States decreases. The prices
for grain and livestock fluctuate according to environmental conditions,
which affect production. This changes economic conditions around the world,
thus affecting demand. Farm crises characterized both the decades of the
eighties and nineties in the United States. Prices fell and caused a decline
in land values. Farmers who had borrowed heavily to expand their operations
and cover operational deficient were forced out of farming when their equity
declined and their cash flow could not justify further borrowing. The situation
in the 1990s was complicated by a dramatic decline in the world price for
grain, as well as wet weather which delayed or prevented planting. Ten percent
of Minnesota's farmers went out of business in 1999. Of those that stayed,
most took second jobs.
The industrialization and globalization of agriculture in North America
has raised difficult cultural and political issues. For many in the agricultural
regions, farming is more than a business. It is a way of life that is quintessentially
American. Yeomen farmers living on their land are the Jefferson ideal. These
households are stewards of the land, the fundamental base of the United
States. As families who have farmed the same land for over a century sell
out, questions are raised about the future of rural North America that demand
answers.
