The biotic cycle is based on the assessment of chemical elements in the production, degradation processes, during the deposition and resynthesis of organic compounds. The biotic cycle of agrophytocenoses, in contrast to natural ecosystems, is characterized by a significant imbalance of macro- and microelements. One way of solving this problem is to approximate the composition and structure of agrophytocenoses to natural plant communities. The objective of the research was to investigate the biotic cycle of elements in single- and mixed-seeded crops of Galega orientalis Lam., Inula helenium L., Symphytum asperum Lepech., urtica dioica L. The research was conducted in the mountainous zone of the Kabardino-Balkarian Republic in 2015-2019 on grey forest soil. In mixed agrophytocenoses, the biotic balance becomes less negative compared to monoculture crops. The excess of consumption over the return of N, Ca, K, P to the soil averaged 3.96; 40.94; 334.02; 9.46 kg/ha, respectively, over 5 years. The inclusion of Galega orientalis in a mixture with nonlegurninous forage grasses increased the soil cultivation index from 0.87 to 0.90. The results show the high potential of a polyculture system based on the combined cultivation of legumes and non-legumes in increasing the sustainability of farming.
