Usage of potential of drained soils due to the maximum attraction of natural biological sources of nutrients is actual and perspective in solving the problem of organic production, namely the use of organo-mineral bioactive fertilizers, improvement of agrochemical and agrophysical properties of peat soil by attracting a subsoil mineral layer rich in nutrients. The purpose of the research was to develop and define the basic principles of organic farming on dehydrated soils. As a result of studies we conducted during 2013-2015 in the Left bank of Forest Steppe on peat-glued soil for growing of winter rye, the influence of the methods of basic soil cultivation, fertilization on changes in water-physical, biological parameters of soil fertility, infestation of crops, formation of a crop, and the quality of the grain of the studied culture. We established that for preservation and increase of fertility of shallow (45-50 cm) carbonate dewatered peat-glue soils of the Left Bank Forest-steppe it is necessary to carry out plowing plowing on 55 cm with a breeding of peat-shaped mineral rock (gleyed light loam) in the thickness of 8-10 cm. Such technological measure provides the yield of winter rye more than 4.8 t/ha with high indicators of product quality.
