Abstract
On peaty-gley soil with content of mineral nitrogen in the early spring period of 50–55 kg/ha, a high supply of mobile phosphorus (875 mg/kg), an increased supply of mobile potassium (805 mg/kg) and an average supply of mobile copper (7,15–7,99 mg/kg), the most effective system for fertilizing perennial grasses is the use of N120P90K150 together with non-root fertilization with copper (Cu80). This fertilizer system provides a conditional net income of 94,07 rubles/ha (38,71 US dollars/ha), a profitability of – 17,1 % and a return on fertilizer of – 18,3 kg of hay, or 9,3 feed units.
