In the article presents the results of study of influence are expounded out of fodder fertilizing on forming of closeness of sowing of sorts of soy depending on the phase of development of plants, and also survivability of plants

Out of fodder fertilizing of soybean agrophytocenosis in the budding phase contributed to the accumulation of plants at the time of harvest at the level of 45.3 pcs / m2, and the survival rate was at the level of 90.1%. Out of fodder fertilizer of sowing in the phase of green beans made it possible to form the sowing density by the time of harvest at a level of 45.4 pcs/m², and the survival rate of the plants was 90.7%.

The combination of out of fodder fertilizing in the budding phases and green beans on soybean agrophytocenoses with the Vuxal Microplant microfertilizer made it possible to form a seeding density of 45.7 pcs/m² of plants in the Kent variety during the harvest period, while the survival rate was 91.3%.

After conducting research, it was found that out of fodder fertilizing, as one of the technology elements, ensured the formation of the survival indices of the agrophytocenosis of soybean varieties of both Merlin and Kent at an appropriate level. In relation to the control variant, the survival rate of plants with the double use of micronutrients increased by 1.8-2.8%.
