Abstract
Data on comparable paybacks of various fertilizer systems are presented as harvest increase for grey forest soils of Opolye in three rotations of eight and seven field crop rotations. With the organic-mineral system with full mineral and appropriate mineral fertilizer systems, the payback of 1 kg acting substance is the highest and close. As the level of fertilizer application increases from 10 to 25 cwt per crop rotation, the acting substance is reduced by the close linear relationship from 6.0–6.5 to 3.5 kg of grain unit/kg acting substance. At appropriate cumulative doses of nutrient application with organic ones and their combination with phosphorous-potassium fertilizers against organic-mineral ones with NPK and mineral (NPK) systems, the payback of 1 kg acting substance with addition is decreased by 1.1–2.7 times.
