In course of the research there was studied effectiveness of phosphate-solubilizing inoculants on crop yield of winter and spring wheat (Triticum aestivum) on eroded sod-podzolic soils on moraine clay loam soil, characterized by different erosion degrees, at various fertilizer systems. The research was realized in the conditions of the Republic of Belarus in a stationary field experiment in agricultural production co-operative 'Mezhany', Braslav area (Vitebsk region) in 2011-2012. As a result of realized research it was revealed that application of phosphorus solubilizing bacteria resulted in the increase of winter and spring wheat yields on watershed, medium- and severely eroded soils under organic, mineral and organic-mineral fertilizer systems. Yield sand values of responses to inoculation depended on slope elements and fertilizer system. The highest yield and gain from the introduction of phosphate mobilizing bacteria noted on non-eroded soil with different fertilizer systems of spring wheat - 42-51 c/ha and 3.6-6.8 c/ha, on winter wheat – 42.1-48.8 and 2.3-3.6 -c/ha of grain respectively. On eroded soils gain from bacterization declined and differentiated as follows: the most important in the system of organic and mineral fertilizers – 5.3-6.4 c/ha (spring wheat) and 2.9-3.4 c/ha (winter wheat), further at mineral fertilizer system - 4.6-4.8 c/ha and 2.4-2.6 c/ha, at organic - 2.8-3.1 c/ha and 2.1-2.4 c/ha respectively.
