INFLUENCE OF AGROTECHNICAL MEASURES ON THE NUMBER AND PHYSIOLOGICAL-BIOCHEMICAL ACTIVITY OF MICROORGANISMS IN GRAY FOREST SOIL
Journal Title: Сільськогосподарська мікробіологія - Year 2018, Vol 27, Issue
Abstract
The influence of agrotechnical measures: mineral fertilization, liming, dipping of biomass of green manure culture and by-products of the precursor in crop rotation on the number and physiological-biochemical activity of microorganisms of the root zone of spring wheat was studied. It has been established that the introduction of mineral fertilizers and liming increases the number of microorganisms of the main ecological and trophic, functional and systematic groups and improves physiological-biochemical activity of representatives of certain groups of microorganisms. The introduction of exogenous organic matter (green manure + by-products of the precursor) allows to reduce the number of melanin-synthesizing micromycetes in gray forest soil by 7.65 %, their specific content in the total number of micromycetes by 47.4 %, reduce the level of phytotoxicity of the soil by 43.4 %. Taking into account long-term data on increasing the number and specific content of melanin-synthesizing micromycetes in soils of contaminated ecotops, this group of microorganisms can be considered as diagnostic in assessing the general level of anthropogenic pollution of agrophytocenoses.
