We carried out research to study the effect of various conditions of mineral nutrition on the soybean productivity under irrigation in the southern forest-steppe of Western Siberia. Under conditions of regulation of water availability, an increase in seed yield (from 1.84 to 2.19 t/ha, or by 18 %) was due to the aftereffect of backgrounds with an increased phosphorus content. The application of phosphorus-containing is effective against the backgrounds with an average availability of labile phosphorus – the soybean seed yield increased from 1.44 to 1.74 t/ha, or by 21 %. In general, an improvement in the conditions of mineral nutrition by pre-sowing application of ammonium nitrate and ammonium molybdate (N30+Mo) against the backgrounds with increased and high Р2О5 content provided an increase in the yield of soybean seeds from 1.44 to 2.44 t/ha, or by 69 %.
