Chapter 8 Flashcards
Allelopathy
The chemical inhibition of one plant (or other organism) by another, due to the release into the environment of substances acting as germination or growth inhibitors.
Best Management Practices (BMP)
Making the most efficient use of animal manures without inflicting damage on the environment.
Composting
Piling organic materials under conditions that cause rapid decay. Reduces the carbon-nitrogen ratio and destroys many weed seeds and disease organisms.
Cover Crop
A close-growing crop grown primarily for the purpose of protecting and improving soil between periods of regular crop production or between trees and vines in orchards and vineyards.
Crop rotation
Practice of growing a series of dissimilar types of crops in the same space in sequential seasons for various benefits.
Fallow
Cropland left idle in order to restore productivity.
Green manure
A crop grown to be turned under while still green to improve the soil.
Mesophilic
Oganisms whose optimum temperature for growth is an intermediate range, between 59 and 95 degrees Dominant microorganisms in early and late stages of composting.
Organic farming
A type of sustainable agriculture that prohibits the use of synthetic substances, including inorganic fertilizers, synthetic pesticides and biosolids.
Organic standards
A framework of guidelines and regulations that govern the production of organic crops.
Sustainable agriculture
Agriculture that, over the long-term, enhances environmental quality and the resource base on which agriculture depends; provides for basic human food and fiber needs; is economically viable; and enhances the quality of life for farmers and society as a whole.
Thermophilic
The description of an organism that thrives at high temperatures.
The chemical inhibition of one plant (or other organism) by another, due to the release into the environment of substances acting as germination or growth inhibitors.
