VERMICOMPOSTING - A STEP TOWARDS ENVIRONMENTAL SUSTAINIBILTY

Nilaja S Paranjape

Abstract


The principal objective of this paper is to understand environmental sustainability is the need of the hour. To achieve this one needs to undertake Natural Resource Management. Vermicomposting is one such method which targets Solid waste management and at the same time provides with organic fertilizer to enhance crop productivity.

Solid waste including agricultural waste, animal excreta, municipal waste, and Kitchen waste is allowed to decompose and broken down by earthworms, bacteria, fungi under a specific environment with temperature ranging between 29-35

The worms eat the biological waste and pass through their body and in the process convert it into vermicompost which is used as fertilizer. Vermicompost supplies a suitable mineral balance and improves nutrient availability.

It minimizes the use of chemical fertilizers, as it proves to be ineffective in the long run. Vermicompost yields correct NPK content to have better crop quality. It is formed of aggregates consisting of minute particles smaller than 5µ, Aggregates are mineral granules bonded together in such a way that they are resistant to water erosion & Compaction. It helps in making soil stable and reduces wind erosion.

Total annual waste biomass in India is approximately 2500 million tons. Vermicomposting cannot solve the problems of solid waste management and soil pollution completely but still a great deal of it can be reduced substantially. It is duty of each citizen of this country to protect and create safe environment for the future generation to come

0C and pH between 5 to 7.
