The influence of mineral fertilizers on the microflora of arable chernozem of the forest-steppe zone of the Trans-Urals

The preservation of soil fertility in the conditions of intensive agriculture is very relevant, and the study of factors affecting it is theoretically and practically necessary. Soil microflora and microbiological processes play a special role in soil fertility. The aim of the research was to study the changes in the structure of soil microflora when applying increasing doses of mineral fertilizers. The study was performed at land plot of the Department of Soil Science and Agrochemistry, State Agrarian University of Northern Trans-Urals, located in the Northern forest-steppe of Trans-Urals. The number of ecological and trophic groups of microorganisms was determined by seeding on nutrient media. The research results showed that low doses of mineral fertilizers had had a weak effect on the development of microbiota. Systematic application of high doses of fertilizers significantly changed the number of soil microflora in the phases of vegetation of spring wheat. The composition of microorganisms on the control and on the variant with the introduction of mineral fertilizers for planned yield of 3...
