Stability and maturity indexes of organic fraction compost

Composting is an environmentally friendly way to turn wastes into useful product (compost). This study aimed monitor various chemical,physical, and biological parameters over the course of co-composting three organic compounds. In this context, 55 kg (55%) ofgreen waste (GW) were co-composted with 40 (40%) poultry manure at 5 (5%) green biochar (GWB).The monitoring experiment continues until final stable. According several previous studies, it was generallyagreed that better employ a combination multiple tests be sure compost has really reached state maturityand stability. During study, series used determine maturity stability forsafe use. Tests during follow-up include pile temperature, moisture, pH, total nitrogen, carbon, C/N ratio, microbialactivity (CO2 emission), germination index, scanning electron microscopy. results carried out thisexperiment, had attained on 54th day from beginning composting.
