The dynamics of nutrients elements and soil micro-organisms content in spring wheat seeds using bacterial complexes

In the conditions of Primorsky Region the dynamics of the content of nutrients and soil microorganisms in spring wheat crops was studied during pre-sowing treatment and seedling spraying with bacterial complex (BC) consisting of nitrogen-fixing (a1), phosphate (f6, f19) and potassium-solubilizing (c2) microorganisms. The studies were conducted on experimental field of the FSBSI "FSC for Agrobiotechnology of the Far East named after A.K. Chaika” (Ussuriysk, Timiryazevsky Settlement) together with the FSC of Eastern Asia Terrestrial Biodiversity, FEB RAS (Vladivostok). The purpose of the study was to assess the effect of bacterial complexes on the dynamics of the content of nutrients, soil microorganisms and that of spring wheat yield. Experimental design included the variants of consortia of nitrogen-fixing, potassium- and phosphate-solubilizing strains obtained from the collection of microorganisms of the FSC of the East Asia Terrestrial Biodiversity, FEB RAS. As the reference, the drug “Extrasol” was used...
