Organic agriculture covers all kinds of food and fiber production system and can be defined as chemical free farming system with an objective to produce food of high nutritional value.

Vermi composting is chiefly composting with worms. In nature, all organic matter eventually decomposes. In Vermi composting, worms are fed with decomposed matter and the organic material will pass through the earthworm gut resulting in worm castings. Vermi compost, enriches soil in most natural organic manner, and also increases the quality, fertility and mineral content of the soil. Unlike chemical fertilizers that destroy beneficial microorganisms, the organic fertilizer is completely harmless & provide rich organic soil that is best for plants.

Hence, Vermi composting involves harnessing of earthworms for cleaning up the environment. In the process, earthworms and microbes work together and produce vermi-compost.

Vermi compost contains more than 8 kinds of useful microbial bacterium groups (over 600 million per gram). So it can supply all nutrition elements needed by the variety of plants. Use of Bio-organic fertilizer will reduce the use of harmful chemical fertilizers; give higher yield & improve soil fertility.

Benefits of using Earthworm Fertilizer

• The earthworms play a vital role in the entire process; in ploughing and fertilizing the soil and providing all the needed nutrition to the plants.

• The earthworms have contributed to improve the soil structure, soil fertility, promote soil aggregation, encourage favorable soil reactions and enrich the nutrient status of the soil and in the process promoting the plant growth and improving the quality of the produce.

• Earthworms churn the soil and make it porous.

• They improve the soil by helping it achieve proper air, water and solids in the required ratio for maximum plant growth.

• Earthworms improve the water infiltration rate. Its maze of tunnels increases the soil's ability to absorb water.

• Earthworms bring up minerals and make plant nutrients more available.

• Earthworms also neutralize soil pH. Analysis of earthworm castings or manure shows that the soil in the castings has neutral pH (7) regardless of whether the existing soil is above or below pH (7).

• Earthworms compost plant residues.

• Earthworms stimulate microbial population. Free-living nitrogen fixing bacteria are more numerous around the sides of the earthworm's burrows.

G.Lienhard, instructor at the School of Agriculture in Ebenrain-Sissach (Switzerland) praises the earthworm: "The earthworm increases the nutrients in the soil significantly"
