Microflora, supply of elements of nutrition of ordinary сhernozem and productivity of spring wheat when applying the preparation «Agrobionov»

Abstract

Abstract The article presents the results of research of the microflora, microbiological activity and nutritional content of ordinary chernozem when applying the preparation «Agrobionov». The aim of the preparation is to give agri-environmental assessment of doses of any preparation in biological properties and availability of nutrients and yield of spring wheat. Иле microbiological activity of the soil has been determined by the method of flax seed application. The following group of microorganisms has been studied: bacteria that utilize organic nitrogen compounds; microorganisms that consume mineral nitrogen; oligonitrophilic; bacteria, mobilizing mineral phosphates; calculatorcredit microorganisms; the nitrifying microorganisms; fungi. The authors have found that studied preparation increases the microbiological activity, the total number of microorganisms, including agronomic valuable microorganisms, the availability of easily hydrolyzed nitrogen in the soil, and the yield of spring wheat.
