Abstract
This study examined the content of nitrogen (N), phosphorus (P) and potassium (K) in Tanya winter wheat plants depending on the concentration of an aqueous solution of catholyte (EKhAV-K) combined with foliar fertilizing with FlorHumate. In all phases of the growing season, tillering–stooling–heading, an increase in the content of N in the leaf and stem mass by 0.04%, 0.19% and 0.07% was shown; the content of P increased by 0.04%, 0.03% and 0.05%; and that of K raised by 0.07%, 0.09% and 0.06%. A 20% aqueous solution of EKhAV-K (pH = 9.0 and ORP = –50 mV) promoted better assimilation of N, P and K from fertilizers. The ecological safety of the wheat grain was established. The accumulation of N, P2О5 and K2О in the experimental variant of the grain was 3.09%, 8.90% and 9.09%, respectively, which was more than in the control variant.
