Essay

The dissertation is devoted to study of a question of a condition of biological activity, structure microbial caenosis, contents humus and basic biogenous elements in soddy-podzolic soils and prodyctivity of barley. The analysis of parameters of biological ac-tivity has allowed to estimate an ecological condition of soils, that proved to be true by close correlation de-pendence between number of separate groups of mi-croorganisms and soil processes and agrochemical quality of soils are established. Experimental data rep-resent a scientific basis for creation ecological safety of system of fertilizer soddy-podzolic soils, which promotes improvement of its properties and increase of prodyctivity of barley.
