Influence plowed maize stalks on the dynamics of microbial indicators in soil

Abstract

If the incorporation of organic matter from treated plots microbiological preparations can be significantly affected by changes in the microbial community of mineralization significantly bulky organic matter. The aim of the study was to determine the basic parameters of soil biogenicity before sowing soybeans on the parcels where the corn was pre-sown under the following fertilization variants: 1. Mineral fertilizer 100 kg N / ha; 2. Corn stalks; 3. Corn stalks + 80 kgN / ha; 4. Corn stalks + 80 kgN / ha +20 lit / ha EM Aktiv. At the beginning of vegetation, microbial soil characteristics up to a depth of 0-20 cm were determined according to the number of different physiological and systemic groups of microorganisms The total number of microorganisms as well as the number of tested microorganism groups had the highest values in variant 4. Given that the synthesis of humus is a long slow process, it can be concluded that the cultivation of maize and the introduction of different groups of microorganisms can affect significant processes in the soil.
