Abstract

Northern Kazakhstan is a region that has been recognized as the main producer of grains in the Republic of Kazakhstan. In fact, the country’s national economy depends on its state. In this article, a brief characterization of soil climatic conditions is provided. The results of a research over years (n=600) are taken in conducting diagnostics and optimization of the nutritional nitrogen of crops within the insufficient and unstable moistening condition in Northern Kazakhstan, in which a normal rain fed is taken into consideration. To do so, the methodology is particularly designed to focus on the evaluation of soil nitrogen state and crops with nitrogen. A new method is presented, offering an alternative way for determining the needs and dose calculation in nitrogen fertilizers based on individual requirements of a crop and some primary factors defining their effectiveness. The method is largely based on an identification of the major factors of soil fertility, which may then form crops efficiency and nitric fertilizers. On the basis of the correlation analysis, a quantitative interrelation of factors with crops efficiency is defined. Besides, optimum parameters for nitrogen in the soils are determined, providing a formation of the maximum efficiency of crops and their potential achievements. Therefore, the proposed technique may allow a purposeful management of soil nitrogen regime, optimizing nutrition and the implementation of crops’ potential capabilities.
