It is suggested that the criterion of environmental assessment of land resources should be productivity of crops, taking into account that productivity can be characterized by indicators in energy units, which combines the energy absorbed by plants of solar radiation, moisture and nutrients of soil. It is determined that the comprehensive study of the eco-sphere and the creation of a system of information about its state is the first principle of rational and comprehensive use of land resources. In general, the ecological and economic study of land resources is a necessary element of improving the process of environmentally sound use of agricultural land, restoring their fertility and productivity, and, finally, the formation of a system of organizational and economic provision of environmental safety in the agrarian sector of the Ukrainian economy.
