• It adds organic matter to the soil and stimulates the activity of soil micro-organisms.
  • It improves the structure of the soil thereby improving the WHC, decreasing run-off, and erosion caused by rain.

  • The green manure takes nutrients from lower layers of the soil and adds to the upper layer in which it is incorporated.
  • It is a leguminous crop, it fixes ā€˜Nā€™ from the atmosphere and adds to the soil for being used by succeeding crop. Generally, about 2/3 of the N is derived from the atmosphere and the rest from the soil.
  • It increases the availability of certain plant nutrients like P2O5, Ca, Mg and Fe.


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 ā€˜Nā€™ 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.
