In a course of the research there was studied the influence of organic and phosphate-potassium fertilizers in yield removal and accumulation of plant nutrition elements in soil by estern galega cultivated for seeds. The research was realized in the conditions of the Republic of Belarus. As a result of realized research there was revealed that the highest removal and the accumulation of plant nutrition elements were provided by the application of 50 t manure per hectare and phosphate- potassium fertilizers in the dose of P60K90. At the end of the vegetation period of the sixth year, the content of nitrogen in a plough layer was 302-325 kg/ha. phosphorus and potassium contents were 99.4-102 and 169-179 kg/ha, respectively. However, on cohesive sandy loam soils of Polesje zone of Belarus under the conditions of sufficient moisture, lodging of seed grass stands was marked at the application of 50 t manure per hectare before seed plot establishment and annual use of P60K90.
