Field tests of 2003-2005 showed that in mixed crops the content of the main feeding elements in grain and straw is lower than in lupine sowed alone, but higher than in spring wheat sown alone, and has the following parameters on the background of N30 in grain: N-4,52%, P2O5 – 0,71%, K2O -1,29%; CaO-0,88%; MgO – 0,20%; in straw: 1,0- 0,34-2,11 – 0,38 – 0,26% correspondingly. An increase in specific consumption of feeding elements is noted: lupine, with seeds inoculation on the background of N30 increased consumption of nitrogen by 11%, phosphorus - 9%, potassium - 23%, calcium - 11%, magnesium - 8%; spring wheat, on the background of N60 increased consumption of nitrogen by 11%, phosphorus - 27%, potassium - 18%. During vegetation the examined crops actively consumed nitrogen, and more than 70% of it (from 73 to 81%) during ripening passed into grain
