Vermicomposting is the biological degradation and
stabilization of organic waste by earthworms and microorganisms
to form vermicompost. This is an essential part in organic
farming today. It can be easily prepared, has excellent
properties, and is harmless to plants. The earthworms
fragment the organic waste substrates, stimulate microbial
activity greatly and increase rates of mineralization.
These rapidly convert the waste into humus-like substances
with finer structure than thermophilic composts but possessing
a greater and more diverse micro-bial activity.

Vermicompost being a stable fine granular organic matter,
when added to clay soil loosens the soil and improves the
passage for the entry of air. The mucus associated with
the cast being hydroscopic absorbs water and prevents
water logging and improves water-holding capacity. The
organic carbon in vermicompost releases the nutrients
slowly and steadily into the system and enables the plant
to absorb these nutrients. The soil enriched with vermincompost
provides additional substances that are not
found in chemical fertilizers.
Many agricultural industries use compost, cattle dung
and other animal excreta to grow plants. In today’s
society, we are faced with the dilemma of getting rid of
waste from our industries, household etc. In order for us
to practice effective waste management we can utilize
the technology of vermicomposting to effectively manage
our waste. This process allows us to compost the
degradable materials and at the same time utilize the
products obtained after composting to enhance crop
