Object of research - technogenic influence of heavy metals in phosphoplaster's sailings on environment. The mathematical model which establishes functional dependence of the maintenance of the investigated migrant in a geochemical landscape from spatial co-ordinates and time is developed. On a basis of experiment researches and mathematical modelling results with the help of regress analysis is established form of dependence between depth of heavy metals migration on a soil profile and phosphoplaster profile and a mode of migrants accumulation in a firm phase. Expansion of capacity of phosphoplaster sailing manufactures of phosphoric fertilizers of VAT "Sumykhimprom" without tap of additional farmland, and also warehousings iron cuporos in a body of the designed sailing is offered. It is offered and investigated antifiltration screen on a bottom, biases and a surface of a bowl of phosphoplaster's and iron cuporos' sailing.
