Implementation of agroecological assessment of soil within the administrative units of Ukraine, followed by agro-ecological zoning of the country as the basis of the strategy of sustainable land use. During agrochemical survey of Sarny district (Rivne region) large-scale ground survey was conducted by two-phase survey. There were examined 54 892 hectares of farmland.
