agroecosystem | An ecosystem created by agricultures. Typically it has low genetic species, and habitat diversity. |
aquaculture | Production of food from aquatic habitats. |
crop rotation | A series of different crops planted successively in the same field, with the field occasionally left fallow or with a cover crop. |
genetically modified crops | Crop species modified by genetic engineering to produce higher crop yields and increase resistance to drought, cold, heat, toxins, plant pests, and disease. |
green revolution | Name attached to post-WWII agricultural programs that have led to the development of new strains of crops with higher yield,better resistance to disease, or better ability to grow under poor conditions |
limiting factor | The single requirement for growth available in the least supply in comparison to the need of an organism.Originally applied to crops but now often applied to any species. |
macronutrients | Elements required in large amounts by living things. These include the big six-carbon, hydrogen, oxygen, nitrogen, phosphorus, and sulfur |
mariculture | Production of food from marine habitats. Marine evaporites.With respect to mineral resources refers to materials such as potassium and sodium salts resulting from the evaporation of marine waters. |
micronutrients | Chemical elements required in very small amounts by at least some forms of life. Boron, copper, and molybdenum are examples of micronutrients. |
monoculture | (Agriculture) The planting of large areas with a single species or even a single strain or sub-species in farming. |
organic farming | Farming that is more natural in the sense that it does not involve the use of artificial pesticides and, more recently, genetically modified crops. In recent years governments have begun to set up legal criteria for what constitutes organic farming. |
pasture | Land plowed and planted to provide forage for domestic herbivorous animals. |
rangeland | Land used for grazing. |
synergistic effect | When the change in availability of one resource affects the response of an organism to some other resource. |
