Vermicompost is considered as a high nutrient biofertilizer with diverse microbial communities, it plays a major role in improving growth and yield of different field crops, vegetables, flower and fruit crops. Vermicompost is a biofertilizer enriched with all beneficial soil microbes and contains all the essential plant nutrients like N, P and K. Vermicompost that is prepared through conventional method has standard values of total nitrogen: 1.94%, phosphorus: 0.47% and potassium: 0.70%. It is also enriched with various micronutrients such as Mg (0.46%), Fe (7563 ppm), Zn (278 ppm), Mn (475 ppm), Bo (34 ppm), Cu (27 ppm).
It can be used to shift from chemical fertilizers to reduce the hazardous effect of chemicals to both crop and human being. Application of vermicompost either alone or in combination with fertilizers the best solution to immediate problem of declining soil fertility and for production of food thus is the best means of abating pollution, soil degradation and discriminate use of chemical fertilizers.
It improves the soil physical conditions which support better aeration to plant root, drainage of water, facilitation of cation exchange, sustained availability of nutrients, and thereby the uptake by the plants resulting in better growth. Use of vermicompost constitutes an important alternative source of fertilizer that has environmental benefits, productivity and crop quality as compared to inorganic fertilizers.
Vermicomposting and its application could be a better option and farmers need to be educated about the importance of vermicompost.
