Green manuring (G.M) It is a practice of ploughing in the green plant tissues grown in the field or adding green plants with tender twigs or leaves from outside and incorporating them into the soil for improving the physical structure as well as the fertility of the soil.
It can be defined as a practice of ploughing or turning into the soil, undecomposed
green plant tissues for the purpose of improving soil fertility. The object of green manuring is to
Add an organic matter into the soil and thus, enrich it with ‘N’ which is the most important and deficient nutrient.
Types of green manuring
There are two types of green manuring:
Green manuring in-situ
When green manure crops are grown in the field itself either as a pure crop or as intercrop with the main crop and buried in the same field, it is known as Green manuring In-situ. E.g.: Sannhemp, Dhaicha, Pillipesara, Shervi, Urd, Mung, Cowpea, Berseem, Senji, etc.
These crops are sown as:
i) Main crop,
ii) Inter row sown crop,
iii) On bare fallow, depending upon
the soil and climatic conditions of
the region.
Green leaf manuring
It refers to turning into the soil green leaves and tender green twigs collected from shrubs and trees grown on bunds, wastelands, and nearby forest area. E.g.: Glyricidia, wild Dhaicha, Karanj.
