🗑
|
||||

|
||||
| show | Crop cultivation method in which a planting surface is made by plowing land, breaking up the exposed soil, and then smoothing the surface.
🗑
|
||||
| show | 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
🗑
|
||||
| desertification | show 🗑
|
||||
| show | Widespread malnutrition and starvation in a particular area because of a shortage of food, usually caused by drought, war, flood, earthquake, or other catastrophic events that disrupt food production and distribution.
🗑
|
||||
| show | Confined outdoor or indoor space used to raise hundreds to thousands of domesticated livestock.
🗑
|
||||
| show | Substance that adds inorganic or organic plant nutrients to soil and improves its ability to grow crops, trees, or other vegetation.
🗑

||||
| fish farming | show 🗑
|
||||

🗑
|
||||

|
||||
| show | 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.
🗑
|
||||
| show | Popular term for introduction of scientifically bred or selected varieties of grain (rice, wheat, maize) that, with high enough inputs of fertilizer and water, can greatly increase crop yields.
🗑
|
||||
| gully erosion | show 🗑
|
||||
| herbicide | show 🗑
|
||||
| show | Same as industrialized agriculture.
🗑
|
||||
| show | Suffered when people cannot grow or buy enough food to meet their basic energy needs.
🗑
|
||||
| industrialized agriculture | show 🗑
|
||||
| inorganic fertilizer | show 🗑
|
||||
| show | Chemical that kills insects.
🗑
|
||||
| show | Combined use of biological, chemical, and cultivation methods in proper sequence and timing to keep the size of a pest population below the size that causes economically unacceptable loss of a crop or livestock animal.
🗑
|
||||
| show | Growing two or more different crops at the same time on a plot. For example, a carbohydrate-rich grain that depletes soil nitrogen and a protein-rich legume that adds nitrogen to the soil may be intercropped.
🗑
|
||||
| show | Simultaneously growing a variety of crops on the same plot.
🗑
|
||||
| land degradation | show 🗑
|
||||
| show | Same as sustainable agriculture.
🗑
|
||||
| malnutrition | show 🗑
|
||||
| manure | show 🗑
|
||||
| show | Ability of a living cell or organism to capture and transform matter and energy from its environment to supply its needs for survival, growth, and reproduction.
🗑
|
||||
| micronutrients | show 🗑
|
||||
| show | Same as conservation-tillage farming.
🗑
|
||||
| show | Cultivation of a single crop, usually on a large area of land.
🗑
|
||||
| no-till farming | show 🗑
|
||||
| show | Producing crops and livestock naturally by using organic fertilizer (manure, legumes, compost) and natural pest control (bugs that eat harmful bugs, plants that repel bugs, and environmental controls such as crop rotation) instead of using commercial inor
🗑
|
||||
| organic fertilizer | show 🗑
|
||||
| overnutrition | show 🗑
|
||||
| pest | show 🗑
|
||||
| show | Any chemical designed to kill or inhibit the growth of an organism that people consider undesirable.
🗑
|
||||
| show | Growing specialized crops such as bananas, coffee, and cacao in tropical developing countries, primarily for sale to developed countries.
🗑
|
||||
| show | Complex form of intercropping in which a large number of different plants maturing at different times are planted together.
🗑
|
||||
| polyvarietal cultivation | show 🗑
|
||||
| show | Accumulation of salts in soil that can eventually make the soil unable to support plant growth.
🗑
|
||||
| show | Occurs when surface water or wind peel off fairly thin sheets or layers of soil.
🗑
|
||||
| shelterbelt | show 🗑
|
||||
| shifting cultivation | show 🗑
|
||||
| slash-and-burn cultivation | show 🗑
|
||||
| show | Methods used to reduce soil erosion, prevent depletion of soil nutrients, and restore nutrients already lost by erosion, leaching, and excessive crop harvesting.
🗑
|
||||
| show | Movement of soil components, especially topsoil, from one place to another, usually by wind, flowing water, or both. This natural process can be greatly accelerated by human activities that remove vegetation from soil.
🗑
|
||||
| show | 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.
🗑
|
||||

🗑
|
||||
| sustainable agriculture | show 🗑
|
||||
| show | Planting crops on a long, steep slope that has been converted into a series of broad, nearly level terraces with short vertical drops from one to another that run along the contour of the land to retain water and reduce soil erosion.
🗑
|
||||
| show | Producing 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.
🗑
|
||||

|
||||
| show | Consuming insufficient food to meet one's minimum daily energy needs for a long enough time to cause harmful effects.
