VERMICOMPOSTING AND VERMICOMPOST
Latin word ‘Vermi’ means worm; thus ‘Vermicomposting’ refers to composting with worms. In vermicomposting, various organic waste materials are broken down by using worms, bacteria, and fungi. These organisms are nature’s vitally useful tools to decompose organic materials. So, vermicomposting is a process that boosts up nature’s process of decomposing organic waste materials and produces a very useful end product.
Vermicompost, the end product of vermicomposting process, is a heterogeneous mixture of decomposed organic wastes, bedding materials, worm castings, decomposed worms as well as other decomposer organisms, worm cocoons etc. The worm castings, one of the major components of vermicompost, contain lower levels of contaminants and higher levels of nutrients than the organic wastes do before vermicomposting. Vermicompost is rich in many water-soluble nutrients which makes it an excellent organic fertilizer.
PLANT NUTRITION WITH VERMICOMPOST
In optimum conditions worms consume huge amount of organic wastes in a day, as much as their own weight at least. After consumption, they take their nourishment from the micro-organisms residing in the wastes; and when they excrete their casts contain an increased number of micro-organisms.
