The research has established patterns of changes in the content of mobile phosphorus in dark gray podzolic soil in the Western Steppes of Ukraine during the growing season of spring barley under the influence of various norms of mineral fertilizers. The research had been performed during 2013 \u2013 2014 years in two-factor field experiment: different rules fertilizer is factor A and foliar feeding preparations of organic origin are factor B.
\nThe use of mineral fertilizers creates favorable conditions for plant nutrition spring barley during the growing season. The highest levels of mobile forms of phosphorus on variations of the experiment received in tillering stage. During the growing season \u2013 and heading to the phase of full ripeness they slightly decreased due to the absorption of phosphorus by plants during power.
\nBy the cultivation of spring barley on unfertilized version received the lowest content of mobile phosphorus in the soil, which were in the layer 0 \u2013 20cm depending on the phase of growth and development of culture 73 \u2013 82mg\/kg soil. The use of fertilizers in normal N30<\/sub>P30<\/sub>K30<\/sub><\/span> and N45<\/sub>P30<\/sub>K30<\/sub> accompanied by growth of its contents in accordance with 23 \u2013 24mg\/kg and 21 \u2013 35mg\/kg soil. With increasing standards fertilizers to N60<\/sub>P30<\/sub>K30<\/sub> \u0456 N45<\/sub>P45<\/sub>K45<\/sub>, trend growth dynamics of mobile phosphorus in dark gray podzolic soil. Excess variant without fertilizers, depending on the phase of vegetation in the upper soil layer (0 \u2013 20cm) was at 17 \u2013 32 \u0456 31 \u2013 41mg\/kg soil.
\nThe highest content of mobile phosphorus occurred concurrently mineral nutrition N60<\/sub>P45<\/sub>K45<\/sub>, which he was in the tillering stage in soil layer 0 \u2013 20cm 124mg\/kg soil, excess control was at 42mg\/kg soil or 51%.
\nIn soil layers 20 \u2013 40 and 40 \u2013 60cm, the content of mobile phosphorus was characterized by slightly lower.
\nBy foliar fertilizing value of mobile phosphorus content was at backgrounds mineral fertilizer.
\nIt was established that there is a substantial connection between the content of mobile phosphorus and norm of fertilizers during the growing season of spring barley. The coefficient of determination in soil layer with 0 to 20cm; in tillering stage was R2<\/sup> = 0,89, earing \u2013 R2 = 0,92, before harvest \u2013 R2 = 0,80.
