Effects of Inoculating Microorganism Agents on Aerobic Composting of Chicken Manure

Abstract

To study the effects of inoculating microorganism on aerobic composting of chicken manure, this paper utilized microorganism agents screened by ourselves to do research on the effect of compost producing organic fertilizer by chicken manure. The temperature, total carbon, Kjeldahl nitrogen, and seeds germination index were measured during the fermentation. The results showed that, compared with CK, the disposal inoculated with microorganism agents could obviously raise the temperature with the highest reaching 63.5°C and accelerate the organic matter decomposing with lower 4 % than control on the 16 d. The contents of Kjeldahl nitrogen declined from 2.44 % to 1.47 %. Furthermore, the seeds germination index achieved 80 % on the 22 d, higher 9 % than the control. The research described the factors in composting process for discussing the relativity of microorganism and chicken manure composting, which could provide the theoretical basis for the harmlessly efficient decomposition and rapid fermentation of poultry manure.
