Green manure is obtained by collection and decomposition of green leaves, twigs of trees, shrubs, and herbs growing in wastelands, field bunds etc. Green manure improves soil structure, increases water-holding capacity, and decreases soil loss by erosion. It also helps in the reclamation of alkaline soils and reduces weed proliferation. It is manure obtained from undecomposed green material derived from leguminous plants e.g. Sunhemp, Dhaincha, etc.
