Role of Microorganisms and Supplement Additives during Sugarcane Straw Composting Process

Microorganisms and supplement additives such as Poultry Manure (PM) - Cow Manure (CM) - Ammonium nitrate (NH3) also have an essential role in enriching and accelerating the sugar cane straw (ScS) residues biodegradation to produce organic fertilizer (compost). Supplement additives may affect physical and chemical changes inside ScS heaps, such as (pH - internal temperature - humidity ratio). These changes also affect the activity of microorganisms in the decomposition of ScS residues. So the main objectives of this investigation are to find out convenient solutions to abate the environmental impact by focused on ScS and their microbiological studies, for production of compost. Microorganisms effect of the ScS decomposition, periods of decomposition and decomposition efficiency. The self-heating temperature increased after two weeks (66.5oC to 72.7oC) was attained. After one month, Self-heating temperature decreased gradually up to the finish of the experiment. PH values recorded after two weeks were ranged of 7.2 to 8.3 throughout the composting operation. Counts of all microorganisms increased during composting process as compared with their initial counts. The total counts of the
