Abstract
Nitrogen-fixing bacteria (Azotobacter chroococcum), phosphate solubilising bacteria (Enterobacter cloacea), sulphur oxidizing bacteria (Thiobacillus thiooxidans), phosphate solubilising fungi (Trichoderma harzianum) were used as a microbial activator in 15 different treatments for composting of bagasse enriched with rock phosphate, urea, and sulphur. The results showed that treatments were treated with Azotobacter bacteria increased nitrogen fixation, especially in the present of phosphate solubilising microorganisms. The soluble phosphorus increased in the treatments that were treated with rock phosphate and phosphate solubilising microorganisms, especially in the present of Azotobacter bacteria. These may have a synergistic effect between the two groups of organisms (phosphate solubilising microorganisms and Nitrogen-fixing bacteria). Production of CO2 by microbial activities and respiration processes, decreased carbon concentrations and C/N ratio.
Keywords: Compost, rock phosphate, sugarcane bagasse, useful microorganisms.
