Despite the great number of studies on the problems of efficient use of land resources in agriculture, the significance of researches is preserved to justify the most important factors forming the microenvironment of land use and to identify internal reserves of growth of its performance at the regional level. The article describes the internal conditions of agricultural land efficiency, their classification based on the organizational, economic, socio-economic and technical-technological factors. Assessing the impact of the considered conditions on the growth efficiency of land use is made through the use of a group of indicators characterizing the general effect of agricultural system usage, the level of resource production potential of economic entities, the existing system of crop rotation as an integral part of farming activities, an indicator of soil fertility, combining the effect of the main qualitative characteristics of the soil. The article also considers the influence of fertilizers use as one of the elements of the farming system onto a plurality of agrochemical parameters provided by a complex coefficient, resulting in a limit of soil fertility, the presence of which is due to the action of the diminishing returns law. On the basis of the results of regression analysis, the farm reserves of the efficiency growth of land resources’ use are revealed, taking into account different levels of soil fertility for agricultural organizations of the central zone of the Krasnodar region. Established that the implementation of intensive agricultural production systems, certainly taking into consideration the requirements of zonal science-based technologies of field crops cultivation allows to achieve high results of land use and to improve soil characteristics of cultivated land
