The purpose of the research is to determine the patterns of fertilizer influence on the parameters of the potential fertility of the soil and the productivity of short-rotation crop rotation crops for different fertilizer systems in the field experiment. Methods of research - field method - to determine the impact of fertilizers on the effective and potential fertility of the soil; laboratory method - to determine the quantitative and qualitative characteristics of research objects; mathematical and statistical - to assess the reliability of the results of research; calculation-comparative - for the economic and energy evaluation of the efficiency of different fertilizer systems in the crop rotation line. In a stationary experiment on a gray forest, large-plow-loam soils, biological fertilizer systems (biological products, by-products of plant growing, organic fertilizers) were studied in short-range 5-field field crop rotation. As a result of the research, standards for the use of renewable resources permitted in organic farming were established and information data were obtained regarding the application of an organic fertilizer system (60 t / ha of manure + straw + biodestructor (for straw), which provides a level of productivity of crop rows of crops (peas - wheat of winter - corn for grain) at the level of 5.34 t / ha z.o, which is one and a half times higher relative to control (without fertilizers) - 3.57 t / ha. For organic fertilizers, humus reserves increased to 36.5 t / ha relative to the baseline (35.1 t / ha), hydrolyzed nitrogen from 50 to 70 mg / kg of soil, and its contents remained low. Biologization measures have led to an increase in the content of phosphorus to a high level of protection, and potassium - to the average content of this element in 0-20 cm layer of gray forest soil.
