The
history of corn is dominated by a rollercoaster of global political interests, production
booms through technological advancements, and a legacy of environmental
destruction. In the early years of this
nation corn was directed by a cycle of subsistence farming, with excess corn
exported as flour, vegetable, or meat products from animals that corn was fed
to. This became the chief product of the
US, and with foreign demand growing the US government decided to create
incentives to expand the farming industry.
These programs were extremely successful, resulting in a migration to
the great plains.
The result
was dramatic. The number of people, and
the invention of devices that made sod busting easier, transformed the
landscape. Within one generation the Tallgrass
prairie was virtually extinct and the Mixed grass prairie was reduced to remnants. All victim of a mass landscape conversion who's
speed of conversion and full extent was completely unprecedented in Human
history. It was an environmental
disaster, but foreign demand was met and the industry prevailed.
Corn
technology continued to improve, and soon processed corn products created an
increased demand for corn. Land was no
longer abundantly available, so an expansion of corn farm extent to meet that
new demand was not possible. Fortunately
for the corn industry, production technology also increased with the
introduction of the green revolution.
Industrial fertilizers and pesticides, along with more efficient
mechanical devices, increased the yield of corn to meet the ever increasing
demand. Though this was called the green
revolution, it had devastating effects on the environment. Fertilizer and pesticide run off from farms
poisoned streams and lakes and even created a massive dead zone in the ocean,
crippling fisheries in the area.
It was in
the late 20th century that there was a sudden shift in attitude. The exploitation of the environment was now
getting attention and the entire countries philosophy was transitioning from
one of exploitation to one of conservation and preservation. Suddenly the price of meeting global demand at
the expense of the environment was deemed too high. Domestic demands started mingling with
foreign demands when it came to corn production. Eventually ushering in laws that banned more
toxic pesticides, put regulation on chemical applications, and put a value on
environmental consciousness.
It was a
new age in corn production, and technology stepped up to meet the new American
consciousness. Soil sensors were used to
measure soil moisture and nutrient availability to determine the exact need of
corn. This allowed the farmer to
carefully gauge the amount of water and fertilizers to his plant's specific
need, which saved money, conserved water, and reduced fertilizer runoff. New genetic modification technology created
plants resistant to pesticides and herbicides, reducing the amount of chemicals
needed which saved money and reduced chemical runoff. Even soil erosion was reduced by leaving a
certain height of stubble on the land after corn harvest. The government also stepped in with initiatives
like the Conservation Reserve Program, which paid farmers to let their farms go
fallow and restore the portions of the prairies that were plowed over a century
before.
Today the global
demand for corn is higher than ever. The
American agriculture industry is able to meet that demand while minimizing
waste and being conservation minded. Pollution from farm runoff is lower, soil erosion
is lower, corn yields are higher despite less land being farmed, and there's
more Mixed and Tallgrass prairie now than at the height of corn expansion. The rollercoaster of the history of corn has
demonstrated the worst and best sides of the industry. With continued innovation the corn industry
can continue meeting global demands while satisfying the conservation minded
social conscience of the American people.
