The effect of the ratio of peat and manure on the efficiency of the fermentation process

Abstract

Manure disposal is one of the main problems of livestock complexes. At the same time animal waste is a very important and valuable raw material in the production of organic fertilizers. The fermentation process was carried out for 6 days; the mesophilic regime was replaced by thermophilic, then the mesophilic period was again established. Air was supplied periodically. Various ratios of peat and manure were used - 40:60, 50:50, 60:40. In each version of the initial mixture, a favorable ratio of carbon to nitrogen was observed - C:N=20-25:1. However the determination of catalase and dehydrogenase activity made it possible to establish the optimal ratio of peat:manure=50:50, at which the value of C:N=22.7:1 and the best conditions are created for the vital activity of microorganisms and, accordingly, the activity of their enzymes. The maximum enzymatic activity contributed to the efficient transformation of organic raw materials. The same amount of manure and peat in the initial mixture contributed to a faster completion of the transformation of the fermented mixture, as evidenced by the redox coefficient in the fermentation product close to 1. With an equal ratio of the initial components, animal waste during the fermentation process is effectively processed into high-quality organic fertilizer.
