In the conditions of the Republic of Belarus there was studied the influence of different types of trace elements on yielding capacity and quality of soybean (Glycine max) grown of sod-podzolic sandy loam soil. In course of the experiment there were applied mineral fertilizers N30-50 against the background of P40K90 applied at pre-sowing cultivation. Different forms of trace fertilizers were used as foliar dressings: boracic acid H3BO3 (300 g/ha), ammonium molybdate (NH4)6Mo7O24 x 4H2O (100 g/ha), manganese sulphate MnSO4 x 4H2O (220 g/ha) - at a budding stage; complex fertilizer N5P7K10B0, 15Mo0,01 – 10 l/ha at budding stage after single application and 4 l/ha at budding stage + 6 l/ha after flowering during double treatment of sowings. Research showed that application of full mineral fertilization system increased soybean productivity by 1.30-1.78 t/ha, with general productivity in variants with fertilization of 2.54-3.02 t/ha and high indicators of economic efficiency of fertilizers application. Non-root treatment of soy crops with microelements and complex fertilizer ensured additional output of bean of 0.14-0.35 t/ha. The content of raw protein in soy beans in variants with fertilizers application amounted to 28.6-33.1%, carbohydrates – 48.2-49.9%, fat – 17.0-18.2%.
