How does green manure enhance soil fertility?
By adding organic matter into the soil, green manures significantly help improve soil structure. Organic matter binds soil particles together and creates soil aggregates. These clusters of larger particles enable formation of pores, which allows for proper soil aeration, water retention and nutrient distribution.
