A cover crop used to add nutrients to the soil and choke out undesirable plants.
A legume crop such as clover that is specifically grown to enrich the nitrogen and organic content of soil.
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. Compare animal manure.
a crop plowed under while still green and growing to improve the soil; sometimes used to enhance populations of antagonistic microorganisms for biological control
A crop like mustard or rye grass that is grown for digging back into the soil to enrich it.
A soil-improving crop grown to be plowed under in an early stage of maturity or soon after maturity.
Plant material incorporated into the soil while green or soon after maturity to improve the soil.
Organic matter added to the soil when a cover crop (often leguminous) is tilled in.
A crop grown specifically for digging back into the soil. These may be grown to protect the ground between crops, to stop nutrients leaking away, or to provide green matter and nitrogen ready for the next crops. Examples include rye, mustard and broad beans. see green manure page
a growing crop that is plowed under to enrich soil
a cover crop which is turned into the soil to add organic matter and, if it is a legume, nitrogen (N)
a crop grown especially to add nitrogen to the soil
manure composed of green plant matter.
The so-called green manure crops, small grains and legumes, are actually cover crops that are grown to improve the soil. Upon maturity, green-manure crops are turned into the soil. This age-old practice produces a large amount of organic matter and releases nutrients into soil slowly as the crop decomposes.
Any crop or plant grown and not harvested that is used to improve the soil's organic matter content and structure. It may or may not be incorporated by tillage.
1. A crop that is grown for soil protection, biological nitrogen reduction, or organic matter and ploughed, disked or hoed into the soil. 2. Any crop grown for the purpose of being turned under while green, or soon after maturity, for soil improvement.
Green manures improve the structure and nutrient load of the soil. They may be undersown between rows of plants or sown as a cover crop. A vital component of crop rotation, green manures may fix nitrogen, concentrate trace minerals in the soil, help break up hard pans (when they are tap rooted), discourage some pests and diseases, and control erosion. Between rows, green manures (like clover or vetch) are often mowed --their clippings left as mulch. At season's end, they are turned in to the soil like other green manures (such as rye and soybeans). See also humus and legume.
A cover crop that is turned completely back into the soil and allowed to decompose. Legume crops often make good green manure crops because they also supply nitrogen. Some green manure crops can be mowed and allowed to grow several times before being tilled into the soil.
A crop of growing plants, such as rye grass, that is plowed under while still green and allowed to decay and enrich the soil. Usually turned over into the soil a few weeks before new planting begins.
Crops or naturally occurring plants that are incorporated into the soil for the purpose of soil improvement.
Vegetation grown to be used as fertilizer for the soil, either by direct application of the vegetation to the soil, by composting it before soil application, or by the leguminous fixing of nitrogen in the root nodules of the vegetation.
Any crop that is grown expressly to be plowed or dug under so as to improve the soil.
Crop grown and plowed under to improve the soil.
Plants such as peas or clover, which are grown for one season, then ploughed under to provide nutrients for an exhausted' field.
A crop planted with the intention of turning it under for use as organic matter.
In agriculture, a green manure is a type of cover crop grown primarily to add nutrients and organic matter to the soil. Typically, a green manure crop is grown for a specific period, and then plowed under and incorporated into the soil.
