Directedness of soil-microbiological processes under the influence of organic and mineral fertilizers

Abstract

The purpose. To study the influence of organic and mineral fertilizers on the development of microorganisms and dynamics of biological processes in soil at growing potato. Methods. Microbiological, field, statistical. Results. At importation into soil of organic fertilizers in the form of dung, straw, mass of lupin green manure crop, and their combinations with mineral fertilizers they observed descend essential changes in structure of microbiota and directedness of biological processes. Conclusions. Organic fertilizers and their combination with mineral ones promote optimization of formation of communities of soil microorganisms, dynamics of biological processes in soil. That positively influences productivity of potato. In ecological aspect, deficiency of organic substance in soil should be considered as undesirable at application of fertilizers because of increased gaseous losses of nitrogen and activity mineralization processes.
