In 2017-2019, it was revealed that fertilizers provide 36 - 51% of the annual crops green mass yield, the collection of raw protein increases by 1.5 - 1.6 times. When N12 was introduced against the background of phosphorus and potassium fertilizers, its content corresponded to 12.50%, and when the N75 was introduced, it increased to 13.6 - 13.7%. Takeaway for N, P, K increased with the use of N75P35K130-160 respectively by 1.5 - 1.6 times, by 40 and 80-90% compared to control. The content of NO3 in green mass increased with the use of fertilizers, amounted to 72 - 86% of the maximum allowable concentration. The doses of N75P35K130-160 fertilizers are 32 - 34 ton/ha of green mass in a vetch and oat mix and the more negative balance of the fertilizer elements investigated.
