It was observed from the results that the thermophilic phase (40-64ºC) was reached earlier in treatment groups which have decomposed earlier i.e treatments 1 and 2. It took more time to reach the thermophilic phase in treatment 3 and 4 due to the addition of coir pith and maximum time was taken in treatment 5 where no bio- accelerator were added. A reduction in pH was noticed in all the treatment groups as the decomposition process progressed.enVeterinary ScienceArticle
