Evaluation of the effect of gypsum application and microbial inoculation on the time of arrival of sugar cane pepper compost

Increasing wastes, especially agricultural waste in recent decades, is a major challenge in human life. To manage and organize waste, composting is an epidemiological approach. Therefore, the aim of this study was to evaluation of the effect of gypsum application with microbial inoculation on the sugar cane pepper compost produce process and to shorten its arrival time. This research carried out under laboratory conditions with two factors including gypsum application (including 10, 5 and 1% wt. Of gypsum) and microbial inoculation (including four levels of control, insemination with bacterial consortium, inoculation with fungal consortium, and simultaneous inoculation of fungal and bacterial consortium) as a factorial experiment based on completely randomized design with three replications. The results showed that microbial inoculation with gypsum application significantly increased the EC value and degradation percentage (3.89 ds/m and 49.14%, respectively, from inoculation with the fungal consortium and bacteria and gypsum 10 percent) and also reduced the pH of the treatments after 90 days of incubation. Microbial inoculation and application of plaster resulted in a significant reduction (P≤0.05) of C/N ratio of cane sugar from 90.93 in non-microbial treatment with 10% plaster to 19.17% in gypsum 10% with fungal and bacterial consortium Became. It also enriched the compost from the elements of phosphorus and potassium. In general, the results of this study showed that inoculation of sugarcane pates with feces of Fasarium and Phanerochaete chrysosporium with Bacillus subtilis and Bacillus firmus, with 10% gypsum application, increased the decay rate of sugarcane bith pulp and reduced the time of composting.
