Application of Microbiological Preparations in the Cultivation of Agricultural Crops with the Aim to Reduce the Technogenic Load of Metallurgical Plants

Abstract

Abstract One of the ways to solve the problem of technogenic pollution is to implement biotechnologies for agricultural lands. The study aims to assess the efficiency of microbiological preparations in the cultivation of potatoes near metallurgical plants in the south of Eastern Siberia. The research was conducted in 2015-2016 on three plots located near Shelekhov aluminum production plant. The Japanese preparation EM and the Russian microbial preparations Baikal EM1 and Fitosporin-M were used. The effect of biological products on plant protection from fungal diseases was observed only in 2015. The two-year application of Fitosporin-M increased the potato yield (by 13-22%) on cultivated alkaline soils; on weakly acidic soils, an increase in the yield (by 26%) was observed only in 2016. When applying EM preparations, a stable increase in the yield (14-22%) was observed on weakly acidic soils; on alkaline soils, an increase in the yield was observed in less than 50% of cases. In general, the stable yield enhancement was observed when applying Fitosporin-M on the alkaline soils. The effectiveness of the EM preparations depended on the agrophone and weather conditions.
