Abstract
The purpose. To demonstrate algorithm of actions on state-of-the-art erosion-preventive optimization of land-use structure on an instance of the concrete agricultural factory. Methods. Cartographical, statistical, geoinformational analysis, mathematical simulation. Results. On an instance of lands of a concrete farm nonconformity of existing use of lands to soil-saving demands is established. On the basis of analysis of potential loss of land for territory of agricultural factory zones with the heightened erosive hazard are determined. Change of structure of crop rotations with creation of 4-field soil protection rotation for erosion hazardous plots and 6-field rotation in other territory is offered. Content is justified and order of crop rotation in crop rotations is elaborated. Mathematical simulation of erosion at different scripts of use of territory showed that implementation of the updated structure of crop rotations would lower erosion to a safety level. Conclusions. The modern land-use, which is founded on out-of-date schemes of disposition of industrial plots, demands their supervisory control with the purpose of assessment of risk of erosion processes. One of ways of such inspection is mathematical simulation of loss of land which can be spent at the level of separate factory and for separate field. The potential hazard of erosion detected as a result of simulation can be prevented by means of organizational and agrotechnical measures that demands from factory minimum economic expenditures. Namely: on the basis of simulation of processes of erosion it is necessary to change regimen of use of erosion-dangerous plots with selection of crop rotations which ensure observance of admissible level of erosion of soils.

Key words: water erosion, agrotechnological group, loss of land, mathematical simulation of erosion, crop rotation.
