Feel free to change the definitions if they aren't right... also we need to know the 1st-3rd green revolutions.
Terms in this set (33)
Nitrogen, Phosphorus, Potassium
Using large inputs of energy from fossil fuels (esp. oil and natural gas), water, fertilizer, and pesticides to produces large quantities of crops and livestock for domestic and foreign sale.
(same as industrialized agriculture) Using large inputs of energy from fossil fuels (esp. oil and natural gas), water, fertilizer, and pesticides to produces large quantities of crops and livestock for domestic and foreign sale.
Growing specialized crops such as bananas, coffee, and cacao in tropical developing countries, primarily for sale to developed countries.
A crop, such as tobacco, grown for direct sale rather than for livestock feed.
Traditional subsistence agriculture
Production of enough crops or livestock for a farm family's survival and, in good years, a surplus to sell or put aside for hard times.
Traditional intensive agriculture
Production of enough food for a farm family's survival and perhaps a surplus that can be sold. This type of agriculture uses higher inputs of labor, fertilizer and water than traditional subsistence agriculture.
Cultivations of a single crop, usually on a large area of land.
Confined outdoor or indoor space used to raise hundreds to thousands of domesticated livestock.
Simultaneously growing a variety of crops on the same plant.
Planting a plot of land with several varieties of the same crop
Growing two or more different crops at the same time on a plot. For example, a carbohydrate-rich grain that depletes soil nitrogen and protein-rich legume that adds nitrogen to the soil may be intercropped.
Conversion of rangeland, rain-fed cropland, or irrigated cropland, or irrigated cropland to desert-like land, with a drop in agricultural productivity of 10% or more. It usually is caused by a combination of overgrazing, soil erosion, prolonged drought, and climate change.
Accumulation of salts in soil that can eventually make the soil unable to support plant growth.
Saturation of soil with irrigation water or excessive precipitation so that the water table rises close to the surface
Methods used to reduce soil erosion, prevent depletion of soil nutrients, and restore nutrients previously lost by erosion, leaching, and excessive crop harvesting.
Crop cultivation in which the soil is distributed little
Planting crops on a long, steep slope that has been converted a series of broad, nearly level terraces with short drops from one to another that run along the contour of the land to retain water and reduce soil erosion
Plowing and planting across the changing slope of land, rather than in straight lines, to help retain water and reduce soil erosion
Planting trees and crops together
Planting of crops in strips with rows of trees or shrubs on each side
Complex form of intercropping in which a large number of different plants that mature at different times are planted together.
Planting regular crops and close-growing plants, such as hay or nitrogen-fixing legumes, in alternating rows or bands to help reduce depletion of soil nutrients.
Row of trees or hedges planted to partially block wind flow and reduce soil erosion on cultivated land
(same as windbreaks) Row of trees or hedges planted to partially block wind flow and reduce soil erosion on cultivated land
Organic material such as animal manure, green manure, and compost, applied to cropland as a source of plant nutrients.
Commercial inorganic fertilizer
Commercially prepared mixture of plant nutrients such as nitrates, phosphates, and potassium applied to the soil to restore fertility and increase crop yields.
Dung and urine of animals used as a form of organic fertilizer
Freshly cut or still-growing green vegetation that is plowed into the soil to increase the organic matter and humus available to support crop growth
Partially decomposed organic plant and animal matter used as a soil conditioner or fertilizer
Planting a field, or an area of a field, with different crops from year to year to reduce soil nutrient depletion. A plant such as corn, tobacco, or cotton, which removes large amounts of nitrogen from the soil, is planted one year. The next year a legume such as soybeans, which adds nitrogen to the soil, is planted.
Popular term for the introduction of scientifically bred or selected varieties of grain (rice, wheat, maize) that, with adequate inputs of fertilizer and water, can greatly increase crop yields
Genetically Modified Organism, Organism whose genetic makeup has been altered by genetic engeneering
