In this article results of studying of an environmental problem as pollution of the soil at use of mineral fertilizers are proved against the background of traditional technologies of cultivation of soy. A comparative assessment of efficiency of resource-saving technology with the studied norms of mineral fertilizers in optimization of an ecological situation of an agroecosystem is given. At traditional technology it is revealed that use of the increased norms of N60P180K90 causes increase in level of impurity of the soil heavy metals and decrease in efficiency of the cultivated culture of soy. The value of resource-saving technology in rational use of bioenergy potential of an agroecosystem is revealed and elements of intensive technology with lower norms of mineral fertilizers for increase in efficiency of an agroecosystem of soy are chosen. It is proved that mineral fertilizers are one of the main factors of stabilization of an ecological condition of the soil, providing increase in efficiency of soy at resource-saving technology of cultivation in the conditions of irrigation of the southeast of Kazakhstan. Application evidence-based resource-saving receptions with elements ecologically safe intensive allows to support technologies rather quickly stability of an agroecosystem.
