Vermicomposting

Introduction

Vermicomposting is the process of converting agro-waste into compost by using earthworms. It provides macro and micro nutrients that are necessary for the growth and development of crops. It is an ideal natural manure that improves the physical, chemical and biological characteristics of the soil.

Farm waste for vermicomposting –

•  Two weeks old farm yard manure.

•  Fruits and vegetables waste.

•  Crop residue and weed etc.

Some common species of earthworms used for vermicomposting are:

•  Eisenia foetida (Red worm)

•  Eudrilus eugeniae (African nightcrawler)

•  Perionyx excavatus (Blue worm)

Most common one is Red worm ( Eisenia foetida ) which is clearly recognized by their alternating red and buff stripes. The worm has a wide range of temperature tolerance but prefers 20-25 C for fast growth, and doubles its population within 2-3 months.
