Abstract


Vermicomposting is a promising method of transforming organic wastes into usable substrates. In this process, the digestive tracts of certain earthworm species (e.g. Eisenia foetida) are used to stabilize organic wastes. The final product is an odorless, clean, peat-like substance, which has good structure, moisture holding capacity, organic material containing relatively adequate quantities of N, P, K and several micronutrients essential for plant growth. The end product of vermicompost is rich in essential macro and micronutrients along with microorganisms in a very simple form. Adding vermicompost not only improves the soil structure and fertility but also leads to improvement in overall plant growth and thus increases their yield. Vermiwash is liquid plant growth regulator, which contains high amount of enzymes, vitamins and hormones like auxins, gibberellins etc. along with macro and micronutrients used as foliar spray. These inputs maintain soil fertility by improving physical, chemical and biological soil properties as well as sustain soil organic carbon and humic substances and can be used to promote the development of beneficial organisms in the soil. It improve soil structure, water holding capacity, seed germination, drainage, base exchange capacity, checks soil erosion and also helps in the uptake of humic substances or its decomposition products influencing the overall growth and metabolism of plants, also improves the hormonal and biochemical activities of humus substances. Hence, these can used very beneficially as a biotic indicators for enhancement of soil health in sustainable agriculture
