Full description
green manure is created by leaving uprooted or sown crop parts to wither on a field so that they serve as a mulch and soil amendment.[citation needed] The plants used for green manure are often cover crops grown primarily for this purpose. Typically, they are ploughed under and incorporated into the soil while green or shortly after flowering. Green manure is commonly associated with organic farming and can play an important role in sustainable annual cropping systems.
