THE INFLUENCE OF MICROELEMENTS ON THE DEVELOPMENT AND PRODUCTIVITY OF CROP YIELD UNDER THE CONDITIONS OF DEGRADED SOILS IN THE SOUTH OF KAZAKHSTAN

In the saline lands, the high concentration of salts not only complicates water inflow, but also breaks the soil structure, reduces its porosity and deteriorates water conductivity that has negative effect on the normal growth and development of crops. For such soils the use of technologies for increase in intensity of growth and development of crops by use of minerals (ZnSO4, CuSO4, NaCl) and stimulant fertilizer (sodium humate) is recommended.
