The research investigates the composting process of mud cake from sugar factories and cattle feces using the microbial isolate Trichoderma viride apt01 to optimize compost quality. Different mixtures of mud cake and cattle feces were analyzed for their carbon to nitrogen (C/N) ratios and pH levels, with the 25/75 mud cake to cattle feces composition yielding the best results (C/N ratio of 14.6 and pH of 6.78). The study concludes that compost produced meets the Bureau of Indian Standards, emphasizing the role of microbial action in improving compost quality for agricultural use.
