Abstract:
In this study, a novel improved technology could be developed to convert
the recalcitrant coir pith into environmental friendly organic manure. The standard
method of composting involves the substitution of urea with nitrogen fixing
bacteria viz. Azotobacter vinelandii and Azospirillum brasilense leading to the
development of an improved method of coir pith. The combined action of the
microorganisms could enhance the biodegradation of coir pith. In the present study,
Pleurotus sajor caju, an edible mushroom which has the ability to degrade coir
pith, and the addition of nitrogen fixing bacteria like Azotobacter vinelandii and
Azospirillum brasilense could accelerate the action of the fungi on coir pith. The
use of these microorganisms brings about definite changes in the NPK, Ammonia,
Organic Carbon and Lignin contents in coir pith. This study will encourage the use
of biodegraded coir pith as organic manure for agri/horti purpose to get better
yields and can serve as a better technology to solve the problem of accumulated
coir pith in coir based industries
