Impact of Green Manure Incorporation on Soil Properties and Crop Growth Environment: A Review

摘要

Green manuring is the process of turning of green plants into the soil either by raising them in samefield or plants grown elsewhere at the green stage before flowering and incorporated into the soil.The greenmanure crops provide multifold advantages. Green manures add organic matter to the soil and recycle nutrientsin to the soil. The nutrients are taken up by the green manure and held inside the plant. Legumes and othernitrogen fixing plants which take nitrogen from the air to the soil are particularly beneficial. The benefits ofgreen manuring are generally interpreted as its capacity to produce or provide nitrogen as substitute forfertilizers. One of the major benefits of green manures is their ability to suppress weeds.Green manures help tostop the soil being carried away by wind and rain.The application of green manures to soil is considered as agood management practice in any agricultural production system because it stimulates soil microbial growthand activity, with subsequent mineralization of plant nutrients.
