Fermentation activity of dung at use of biologically active specimens

Abstract

The purpose. To determine basic indexes of fermentation activity in dung of cows at mesophilic fermenting in anaerobic conditions (in vitro) at use of different biologically active specimens (BAS) and determination of efficiency of activation of methanogenesis processes. Methods. Chemical-analytical, mathematical-statistical. Results. Experimentally it is proved that biologically active specimens raise level of CO2 and CH4 in manure substratum. Liberation of these gases was more in comparison with control, accordingly in the Ist alternative on 15% (BAS + Fe+3, Fe+6 + glauconite), in the IInd — on 4% (complex BAS with phosphoric joint in various densities of P200, P1000), the IIIrd — on 8% (microbal specimen «Cellulose destructor» in dilution 1:500). Conclusions. Effective action is established of biologically active specimen which consists of Fe+3, Fe+6 and natural mineral of glauconite in dilution 1:200– 1:1000 on basic indexes of fermentation activity of dung.
