In the stationary field experiment we have identified the ecological and economic efficacy of the biological preparation
Optimize 200 based on nodule bacteria Bradyrhizobium japonicum for presowing inoculation of soybean seeds under
conditions organic farming systems. Twice during the growing season (at the phase of formation the third ternate
leaves and maturation phase) in the soil of soybeans plants’ root zone (in the phase of formation of the third ternate
leaves and maturation phase) we have identified a number of microorganisms belonging to main ecological and
functional groups and the soil enzymatic activity. It was found a significant positive impact of microbial preparation on
the number, structure and function of microbial communities and biochemical activity in the soil of soybeans plants’
root zone and soybean yield. The results showed the feasibility of using Optimize 200 in organic production of
soybean cultivar Diana on chernozem podzolized.
