Microorganisms play important roles in the recycling of agricultural wastes. Composting is the degradation of organic materials through the activities of diverse microorganisms. The compost generated by bioconversion of agro-residues offers several benefits such as enhanced soil fertility and soil health which can lead to increased agricultural productivity, improved soil biodiversity, reduced ecological risks and a healthier environment. This investigation examined the microbial community dynamics, loads and identification of microbiota at various stages of composting process. The compost produced from combinations of fresh and dry cocoa pod husk, Chromolaena odorata and cow-dung were assayed. Composts samples were randomly collected, isolation by standard serial dilution method and identification of microbes from compost materials were carried out at inception, 2, 4, 8 and 12 weeks after set-up of composting. Microorganisms isolated and characterized from the above composts include the species of bacteria viz., Pseudomonas spp., Staphylococcus spp., Streptococcus spp., Escherichia coli, Bacillus spp., Micrococcus spp., Proteus spp., Streptomyces spp,, Enterobacter spp., Serratia spp., Salmonella spp. and Shigella dysenteriae and fungi viz., Trichoderma spp., Geotrichum spp. Chrysosporium spp., Aspergillus spp., Yeast spp., Absidia spp., Mucor spp., Rhizopus stolonifer, Penicillium spp., Fusarium spp., Phimbens spp., and Microsporium spp. | Microbiota assay of cocoa pod husk – Based compost as organic fertilizer
