Question

Name the organism used in the preparation of vermicompost.

Answer 1

Hint:-The process of conversion of organic waste matter into the nutrient-rich matter by using worms is known as vermicomposting. The product obtained after vermicomposting is called vermicompost. This process requires the continuous rearing of worms which is called vermiculture.

Complete answer:
The process of vermicomposting is an eco-innovation for the treatment of biowaste. It makes use of different worms, most primarily the earthworms which act as natural bioreactors for the decomposition of the organic matter. The earthworms live on the decaying organic matter and help in their faster decomposition by excreting casts. The cast is rich in nitrates and other micro and macro elements like phosphorus, magnesium, calcium, and potassium. This humus-like decomposed soil is used as a fertilizer and enhances the soil fertility. An increase in organic content improves the quality of soil like the soil texture, and the water holding capacity. It also provides aeration to the soil. They restore the microbial flora, like nitrogen fixers and phosphate solubilizers, and provide necessary nutrients to the plants. They promote better nutrient absorption by roots and help in their growth. They help to increase the crop yield by nurturing the soil with plant growth hormones such as auxins and gibberellins. The use of vermicompost helps in reducing the usage of pesticides and synthetic fertilizers.

Note:- Vermicompost is clean, sustainable, and generates zero waste, and does not have any adverse impacts on the environment or plants. Because of these beneficial properties, it is a desirable product for agronomic purposes like gardening and agriculture and also for the remediation of polluted areas.
