Agricultural sciences Definition, History, Disciplines, & Importance

The farmer has been enabled to increase yields per acre and per animal; reduce losses from diseases, pests, and spoilage; and augment net production by improved processing methods. Overpopulation has pushed a growing number of farmers onto lands too fragile to sustain cultivation. In some areas, irrigation has caused water tables to drop, rivers to run dry, and wells to go empty.

The number of women working in agriculture has risen and the 2002 census of agriculture recorded a 40% increase in the number of female farm workers. Inequality and respect are common issues for these workers, as many have reported that they are not being respected, listened to, or taken seriously due to traditional views of women as housewives and caretakers. Agriculture in the United States is primarily governed by periodically renewed U.S. farm bills. Governance is both a federal and a local responsibility with the United States Department of Agriculture being the federal department responsible. Government aid includes research into crop types and regional suitability as well as many kinds of subsidies, some price supports and loan programs. U.S. farmers are not subject to production quotas and some laws are different for farms compared to other workplaces.

Farming with oxen did allow the colonist to farm more land but it increased erosion and decreased soil fertility. This was due to deeper plow cuts in the soil that allowed the soil more contact with oxygen causing nutrient depletion. In grazing fields in New England, the soil was being compacted by the large number of cattle and this did not give the soil enough oxygen to sustain life.
