Agriculture
The objective of agriculture is to collect and store solar energy as
food energy in plant and animal products, which are then distributed to
serve as food for the human population. To collect solar energy in plants
and animals and to help crops convert this solar energy into food energy
and then to distribute the food products, farmers spend fossil-fuel
energy and electric energy in tilling the soil, fertilizing, irrigating,
harvesting, and processing.
New kinds of energy have helped to make a revolution in farm life,
farm work, and farm output since 1900. Only a hundred years ago in
the United States most people were rural people: farmers, planters,
trappers, and pioneers. In the nineteenth century, most work was done
on farms by muscle power, human or animal. The chief sources of
energy for heating were wood and coal. Many farms were fortunate
enough to have a windmill for pumping water. In 1900 one farmworker
was able to supply the needs of about seven people. In contrast, a
farmworker today supplies the needs of 50 people.
The first major contributions that energy made to farming were in
the use of commercial fertilizer, an energy-intensive product, and in
factory-made farm machinery, which required energy to produce.
Motorized farm machinery, which also required energy for its operation,
first became practical for the farmer around 1910 when farm tractors
became available.
During the period of 1900 to 1971, the size of the average farm in
the United States more than doubled while the farm population declined
to one-third of its 1900 level. This change was made possible by the
introduction of new technologies to the farming process, including the
use of tractors, commercial fertilizers, motorized harvesters, and new
scientific methods of farming. By 1975 there were approximately 5
million tractors in use in the United States with a total capacity of 250
million horsepower, consuming 21 gallons of gasoline and 20 gallons
of diesel fuel per capita in the United States. The use of commercial
fertilizer grew by a factor of approximately 14 during the period 1900
to 1970 and is a crucial factor in the ability to increase crop yield per
unit of land cultivated.
