In course of the research there was studied efficiency of complex application of macro- and micronutrients at barley (Hordeum vulgare) cultivation on sod-podzolic sandy soil. The research was realized in the conditions of the Republic of Belarus in Minsk region in 2010-2011. As a result of realized research there were revealed positive influence of optimum mineral fertilizers doses N70+40P60K150 in a combination to copper and magnesium micronutrients on grain productivity. The tendency to decrease in productivity of barley grain was noted at increase in a dose of the cobalt brought in soil. Specific removal of nitrogen, phosphorus, potassium from 1 t and the corresponding principal amount of by-products with a yield 47.7 c/ha was 22.4, 7.8 and 12.2 kg/t, respectively. Inclusion in barley fertilizer system of copper, manganese and cobalt micronutrients had no effect on the value of the specific removal of nutrients.
