The goal of the research is to establish the patterns of the influence of fertilizers on the parameters of the potential soil fertility and crop productivity of short-term crop rotation with various fertilizer systems in field experience. Research methods - field method - to determine the effect of fertilizers on the effective and potential fertility of the soil; laboratory method - to determine the quantitative and qualitative characteristics of the objects of study; mathematical and statistical - to assess the reliability of the results of research; calculated and comparative - for the economic and energy evaluation of the effectiveness of various fertilizer systems in crop rotation. In a stationary experiment on a gray forest large-silvato-loamy soil, biological systems of fertilizer (biological products, plant by-products, organic fertilizers) were studied in short-crop 5-field crop rotation. As a result of research, standards were established for the use of renewable resources permitted in organic farming and the obtained information on the application of an organic fertilizer system (60 t / ha of manure + straw + biodestructor (for straw) provides the productivity level of crops of the crop rotation link (barley - winter wheat - corn for grain) at the level of - 5.74 t / ha z.o, which is one and a half times higher relative to the control (without fertilizers) - 3.73 t / ha. When organic fertilizers were applied, the humus reserves increased to 39.4 t / ha relative to the initial level (35.1 t / ha), hydrolyzed nitrogen from 50 to 70 mg / kg, its content remained within the low level of availability. Means of biologization contributed to the increase in the phosphorus content to the level of high supply, and potassium to the average content of this element in the 0–20 cm layer of gray forest soil.
