Moskalets V. Agroecological aspects of microbial preparations use on the crops of soy plants

In the dissertation the results of research on application of biopreparations and microelement fertilizers on the crops of soy plants are stated. The obtained data shows the important biological part of biopreparations in the formation of sustainable agroecosystems. This proves the ability of biopreparations' bioagents for adaptation to bad environmental conditions (pH soil of field is between 5,0 and 5,5), to be the alternative to the mineral fertilizes; to establish close symbiotic relations with soy plants and promote the formation of high productive symbiotic systems with the background of occasional inoculation of nodules bacteria soil population in the conditions of north part of Ukrainian Wood-Steppe region. It is shown that joint use of rhysobofite and albobacterine increases the general quantity of registered while soy vegetation molecular atmospherical nitrogen from 6 up to 47 kg/ga, provides the increase of abovesoil plants mass for 19, the leaves area for 21, grain crop for 8 up to 11, protein in grain for 1,7-3,3%. The application of the biopreparations overwhelms the effect of use of mineral fertilizes in the dose of N30P30K30. The plant reaction on the non-root application of microelements caused the increase of the crop, with more probability while using the biopreparations. The microbial preparations are recommended for use for creation of ecologically safe soy cultivation methods.
