Question

how is vermi-composting useful in agricalture

Answer 1

Earthworms feed on decaying organic material and deposit castings—a natural fertiliser. The process by which these earthworms can be cultured or used in composting pits, crates, tanks, concrete rings or any containers is commonly known as vermicompost. About 2500 species of earthworms have been identified world over of which more than 500 species are found in India. Diversity of earthworm species varies with different types of soils and hence choosing a local or native species of earthworm for vermicomposting is an important step. Local species of earthworms that are used in India are Perionyx excavatus and Lampito mauritii. Vermicompost is considered superior to other types of compost due to its low investment need and high quality of product. India being a agriculture centric country could easily use millions of tonnes of vermicompost and considerably reduce its dependency on chemical fertilisers.

Answer 2

Heya !!

In vermicomposting , a pit is dug out and filled with leaves ,twigs, seeds, dry fruit ,vrgetable peels and many such house wastes. It becomes a little ecosystem housing the red earth worms which eat these waste materials, digest them and their fertile excreta can hence be used as rich organic matter -manure . This fertile manure increases the fertility of the soil . Therefore using vermicomposting in agriculture makes the soil more fertile which will in turn produce a better yield (better crops )

Hope that helps !
