In this article it is reasoned the importance of solving the problem regarding the correct location of agricultural crops according to categories of land subject to erosion and of crop rotation grounds in the working conditions of agricultural activities from the Republic of Moldova, as well as the necessity of finding the right variant under the use of the economical and mathematical simulation with the aim of minimizing the quantity of solifluction. Calculations are performed according to the data from the Colibabovca village of the Leova district. The obtained results show us that the optimal location of the six crops on the descents of three land categories subject to erosion and ground of field crop rotation (149,74) and antierosional crop rotation (461,39) will allow to minimize the quantity of solifluction from snow melting, and pouring rain, which will equal to 955.8 tons, i.e. 25,2 % less than the one calculated by the traditional method.
