In the conditions of the Republic of Belarus on sod-podzolic loamy sandy soil application of mineral fertilizers N10-50P40K90 made it possible to increase yield of soybean (Glycine max) grain of Pripyat variety on 6,7-17,8 centner/ha with the total yielding capacity in the fertilized variants 19,1-30,2 centner/ha, and payback of 1kg of NPK 4,8-9,9 centner/ha, content of crude protein – 26,9-31,5%, and profitability – 149-274% with the maximal indexes in the variant with application of N50P40K90 at pre-sowing cultivation. The inoculation of soybean with nitrogen-fixing bacterial preparations based on stamp Bradyrhizobium japonicum made it possible to increase the productivity of bean at 0,39-0,68 tha-1, the content of crude protein at 5,0-5,5%. The complex use of mineral fertilizers, phosphate- and nitrogen-fixing bacterial preparations has increased the productivity of soya bean at 1,22-1,72 tha-1 with a total productivity 2,46-2,96 tha-1, with the content of crude protein 29,0-33,4%, with net income 737,6-1129,8 thousand rubles, with profitability 246-340% with the possible saving of mineral nitrogen and phosphorous fertilizers in the dose of 20 kgha-1.
