- Composting is one of the most successful biological processes for treatment of wastes residues. Microorganism's activity during composting of waste materials were influenced by initial carbon/nitrogen ratios and physicochemical changes, e.g., electrical conductivity, temperature, pH, organic matter (OM) degradation, and total nitrogen (TN) losses. Compost heap was formed from mixture of rice straw, sugar beet straw and chicken manure. Also, total count of bacteria, fungi, actinomycetes, detection of pathogenic bacteria such as total and faecal coliform bacteria and salmonella were determined. Some physical and chemical analysis of compost during process was determined to determine compost maturity such as phytotoxicity and nitrification index. Thermophilic phase during composting process was decreased numbers of pathogenic microorganisms and after one month disappeared. Also, at the end of process E.C values were decreased after 4 months and germination index recorded 88.1% for maturity of compost.
