Agroecology is an academic discipline that studies ecological processes applied to agricultural production systems. Bringing ecological principles to bear can suggest new management approaches in agroecosystems. The term can refer to a science, a movement, or an agricultural practice. [1] Agroecologists study a variety of agroecosystems.
A new variety might, for example, be higher yielding, more disease resistant or have a longer shelf life than the varieties from which it was bred. The practical use of crop diversity goes back to early agricultural methods of crop rotation and fallow fields, where planting and harvesting one type of crop on a plot of land one year, and ...
Intraspecific diversity, the variety of alleles within a single species, also offers us a choice in our diets. If a crop fails in a monoculture, we rely on agricultural diversity to replant the land with something new. If a wheat crop is destroyed by a pest we may plant a hardier variety of wheat the next year, relying on intraspecific diversity.
Natural color in cotton comes from pigments found in cotton; these pigments can produce shades ranging from tan to green and brown. [3] Naturally pigmented green cotton derives its color from caffeic acid, a derivative of cinnamic acid, found in the suberin (wax) layer which is deposited in alternating layers with cellulose around the outside of the cotton fiber.
Self-pollinated varieties are similar to open-pollinated varieties in that they are true-to-type and seed is collected at and stored from each harvest, but measures are taken to minimize outcrossing. This may involve placing a barrier such as a mesh bag or cage over the plant to prevent pollinators from reaching flowers, ensuring that the plant ...
Early Girl hybrid tomato (large, light red on the right), alongside a selection of heirloom tomatoes. Early Girl is well-suited to dry farming. [6] Researchers at the Center for Agroecology and Sustainable Food Systems at the University of California, Santa Cruz, are among those who have described the technique of not watering after transplanting, forcing the roots to grow deeper to seek out ...
One of the major efforts of disciplines such as agroecology is to promote management styles that blur the distinction between agroecosystems and "natural" ecosystems, both by decreasing the impact of agriculture (increasing the biological and trophic complexity of the agricultural system as well as decreasing the nutrient inputs/outflow) and by ...
The wild relatives of crop plants constitute an increasingly important resource for improving agricultural production and for maintaining sustainable agro-ecosystems.
