Abstract
The experience of agriculture in the Republic of Kazakhstan and other countries shows that high and sustainable agricultural productivity is possible only with a comprehensive soil examination in order to control and assess changes in fertility and the level of pollution caused by anthropogenic factors to prevent land degradation. The article provides a brief description of the soil cover and an assessment of the current state of soil fertility of the Kostanay region, which allows to solve problems with resources and limiting factors of soil fertility, heat, moisture and potential for development of degradation processes, the formation of environmental infrastructure of the agricultural landscape, etc. Morphological and physical and chemical analysis of soils was carried out in the research. The data of previous years have also been studied and the change in soil properties over the course of long-term agricultural use has been analyzed. The analysis of the current state of soils is given and the assessment of soil fertility is carried out.
