Abstract


Green manuring is the practice for improving soil fertility and productivity by ploughing and turning undecomposed green plant tissue into the soil. It adds organic matter in to the soil and improves water holding capacity. There are two types of green manuring, i.e. green manuring in situ and green leaf manuring. Green manuring in situ means green manure crops like Cowpea, Dhaincha, Sunnhemp etc. are grown and incorporated in the same field. Green leaf manuring is pruning of green leaves or twigs from various trees like Glyricidia, Pongamia, Subabul, etc. are collected from elsewhere and incorporated in to another field as manure. It improves the soils’ physio-chemical and biological properties and fertility.
