Effectiveness of the influence of different doses of biopreparations on the emission of harmful gases from pig manure

The anthropogenic influence of agriculture on the atmosphere is carried out due to the accumulation of by-products of animal husbandry, which serves as a source of emission of pollutants, including harmful gasesammonia (NH3), hydrogen sulfide (H2S), nitric oxide (NO) nitrous oxide (N2O), methane (CH4), carbon dioxide (CO2).The livestock industry, in particular pig farming, occupies one of the leading links in ensuring the food security of the state and at the same time is a producer of a significant amount of waste, the accumulation of which leads to a negative impact on the environment.The basis of the planned research was the establishment of the effectiveness of the use of biopreparations -AgroMar D and Reduklin-Compost in different doses on the level of emission of harmful gases -NH3, H2S, NO, CH4, CO2 from pig waste in vitro.The analysis of the obtained results indicates a reduction in emission of the studied gases from pig manure when using different doses of biopreparations -AgroMar D and Reduklin-Compost, but the best results were observed at a dose of 40 ml/m 3 .In a comparative assessment of the influence of the above biopreparations on the emission of harmful gases from pig waste, it should be noted that the level of NH3 release decreases with the introduction of biopreparations AgroMar D and Reduklin-Compost, respectively, to 10.2 % and 15.7 %, H2Sto 12.2 % and 20.8 %, NOto 11.5 % and 13.3 %, CH4to 6.9 % and 10.3 %, CO2to 13.1 % and 14.4 %.Simultaneously with the reduction of release of gases, the addition of biopreparations ensures a lower level of the manure pH indicator.Thus, the obtained data indicate the expediency of using the studied biopreparations, in particular, Reduklin-Compost to decrease the level of harmful gases release during manure storage.It can be used as well directly in premises for keeping pigs, which will ensure a reduction of the negative effects of pig farming on the environment, thereby preventing violation of the ecological balance in the natural environment.
