Restoration of fertility of gray forest soil for management of intensive and organic agriculture

The scientific substantiation of the authors on the essence of reproduction of fertility of acid gray forest soils, its types and forms of manifestation, factors of increase and regulation under conditions of intensive and organic agriculture is presented. An in-depth analysis of the amount of humus in loamy soils, a set of agrotechnological measures and patterns aimed at preventing the degradation of acidic gray forest soils and protection of their fertility in the agrocenosis with different technologies for growing crops. The optimal parameters of humus content and reserves and ways to achieve at a consistently high level of basic nutrients in gray forest soils with organic and intensive use are determined. Based on many years of research, the main issues are considered and the effectiveness of action and aftereffects of periodic chemical reclamation in combination with organic and mineral fertilizers is proved, and the effectiveness of one and a half dose of ameliorant for long-term intensive mineral load in agrocenosis is substantiated. The comparative productivity of agrocenosis for III and IV rotation on gray forest soil for organic farming is given.
