Abstract

Northern Kazakhstan is the basic region producing grain in the Republic of Kazakhstan. National economy depends on its state. A brief description of the characteristics of soil and the climatic conditions is given in the article. The results of years’ research (n=600) in diagnostics and optimization of crops’ nitrogen nutrition in the conditions of insufficient and unstable moistening of Northern Kazakhstan are considered in this article. The methodological approach to the evaluation of soil nitrogen state and crops with nitrogen is explicated. New method of determining the needs and dose calculation in nitrogen fertilizers with individual requirements of crop and the main factors defining their effectiveness is represented. The method is based on identification of major factors of soil fertility defining the efficiency of crops and nitric fertilizers. On the basis of the correlation analysis, the quantitative interrelation of factors with efficiency of crops is defined. Optimum parameters for measuring the content of nitrogen in the soil required for the maximum efficiency of crops and ways for achieving it are determined. The method considers individual requirements of crops and the main factors defining effectiveness. The developed technique allows purposefully managing soil nitrogen regime supplying optimization of nutrition and implementation of crops’ potential possibilities
