Abstract

The purpose. To determine modern lines of quantitative and qualitative changes in land-resource potential, directions, legal premises and volumes of land-protection operations. Methods. Analysis, synthesis, system of generalization, calculation-alternative, prediction. Results. Features of work on protection of lands in pre-reform and after-reform periods are considered. Methodological approaches are justified concerning prediction of content of ecologically stabilized lands by application of indexes of edaphic features. That will stipulate necessity of rust-preventive treatment of lands. Legal statuses of formation of the act on this question are offered. Directions are offered of perfecting control over land-use and soil fertility. Conclusions. It is necessary to transmit control over protection of lands to the Ministry of agrarian policy and food, and to create the specific structural organ in its structure. It is also necessary to integrate scientific, design, agrochemicaland-passport and monitoring operations on the basis of use of the newest laboratories and materials of remote sensing of lands.
