The purpose of the research is to determine the parameters of the indicators of the fertility of gray forest soil and the productivity of field crop rotation for different fertilizer systems in the long-term experiment. To establish regularities of the influence of fertilizers on integrated and biological fertilizer systems in short-rotation crop rotation for different tillage of soil to change the agro-chemical indices of typical chernozem fertility. In the conditions of a new field experiment, on the gray forest soil of the highest level of crop productivity, crop rotation levels were achieved at an intensive organo-mineral fertilizer system of 12 t / ha of litter manure + (N60P60K68), under such conditions improved nutritional status, biological activity, and level crop rotation productivity at the level of 6.36 t / ha z.o. In the chernozem of the typical Panfil Research Station, it is determined that the best predecessor for growing winter wheat is soybean compared to rape. For fertilizer application (intensive fertilizer system), as well as for biologized fertilizer system, the yield of winter wheat (rapeseed predecessor) was found to be 33% and 44% lower in comparison with cultivating this crop after soybeans. The highest grain yield of 4.99-5.26 t / ha was in the biologized fertilizer system, regardless of the method of cultivation for the precursor of soy. Product Description popup.authors Ігнатенко Ю.О.
