Abstract: By the results of long-term experimental researches of activity and orientation of biological processes in the soil of natural ecosystem and agricultural ecosystem, the yield of winter wheat under different fertilizer systems and considering hydrothermal factors, we have obtained the relations between the biological activity of the soil and weather conditions and yield. The author has constructed a generalized mathematical model of agricultural ecosystem productivity considering weather conditions, the biological activity of the soil and fertilizing systems. Calculations have confirmed the validity of each received dependence and generalizing model of agroecosystem productivity
