САНИТАРНАЯ БЕЗОПАСНОСТЬ УДОБРИТЕЛЬНОГО МЕЛИОРАНТА НА ОСНОВЕ КОЗЬЕГО НАВОЗА

Abstract

Fertilizing ameliorants based on organic fertilizers, in particular, goat manure with the introduction of sewage sludge from the municipal economy of the Ryazan region, chopped straw and a complex of effective microorganisms should have a benefi cial effect on the soil and plants and not pollute the environment. For this, it is necessary to compare the actual values with sanitary standards. One of the polluting factors are microorganisms entering the environment from the ameliorant being introduced. The safety of soil, natural and ground waters, and crop production is an important problem when carrying out restoration measures on degraded drained peat soil. Based on the above, the research topic is relevant. The research included laboratory methods based on analysis, logic, comparison. The experimental scheme concerned different doses of the ameliorant applied to the soil when regulating the water regime through irrigation. The research will ultimately help to develop practical recommendations for agricultural holding Novoselki, which uses the agricultural landscape as fodder land. In the process of research, a direct dependence of the degree of environmental pollution on the dose of the ameliorant was revealed. At the same time, an active process of self-purifi cation of all environments (soil, natural and lysimetric waters) was clearly traced, that confirmed the total content of mesophilic aerobic and facultative anaerobic microorganisms that have grown at 37°C and the total number of mesophilic aerobic and facultative anaerobic microorganisms that grew at 22°C. The content of Escherichia coli and the total microbial number on the 21st day after the introduction of UM decreased in media by 1.5-2 times. In all environments, pathogenic microfl ora and eggs of helminths were not detected in all years of the research. The introduction of a fertilizer ameliorant into the soil at the rate of 15 t/ha is the most optimal one from the agronomic point of view. The dependence of the degree of environmental pollution on the dose of the ameliorant application, considering the intensive self-cleaning process, was not revealed in all environments of pathogenic microfl ora and helminth eggs in all the years of the research. Herbal products are safe. It is permissible to use grown products for haylage.
