Regulation of fertility of soils and efficiency of fertilizers in conditions of climate fluctua- tions

Abstract

The purpose. To determine regularities of effect of warming of a climate upon fertility of soils and utilization of nutrients by plants. Methods. Systems analysis, field and laboratory probes. Results. The possibility is substantiated of adaptation of fertilizer system and sorbtion of microelements by plants for heightening their resistance in conditions of aridity of a climate. Conclusions. At warming of a climate the directedness of processes of interaction of nutrients with soil varies. Speed of phosphates’ saturation increases. In drought years productivity of sugar beet is positively influenced with the high content of mobile potassium in soil.
