The purpose of the study is to study the energy potential of black earth typical for the use of farming systems in grain-crop rotation. During the researches, field, laboratory and calculation methods were used. Cultivation of crop rotation under an intensive crop system (N92P100K108 per 1 ha of crop rotation) reduced the soil organic matter reserves and reduced its energy potential. For the period of two rotations, the typical black earth energy intensity decreased by 42.6 GJ/ha. The use of an ecological farming system has helped to stabilize the energy balance of the soil. Application for reproduction of soil fertility of organic fertilizers with application of 12 t / ha of manure per hectare of crop rotation and 6 t/ha of byproducts and weight of crop sideratas and 150 kg of mineral fertilizers (N46P49K55), provided an increase of soil energy up to the initial average of 1 year on average 1,68 GJ/ha. Further studies on the energy potential of black earth typical of crop rotation, taking into account different sources of organic matter input to the soil, are the basis for the development of an environmentally balanced and efficient system of agriculture
