Abstract

Soil fertility in Kazakhstan's main grain-growing regions is essential for successful agriculture, and its preservation is a top priority for farmers. Chernozem soils are prevalent in the northernmost part of the country, covering the entire North Kazakhstan region, most of the Kostanay region, and the northern regions of the Akmola region. All chernozem soils are fertile, but they are classified as low-moisture (less than 40 cm) with a content of organic matter of 6-8 % in the first two, and 4-6 % in the southern chernozems. The paper presents the results of research on the content of organic matter (humus) in the arable soil of the North Kazakhstan, Kostanay, and Akmol regions during the cultivation of field crops. The object of the study was the arable soil of agricultural formations. The method of determining the percentage of humus content is based on the oxidation of organic matter with a solution of potassium dichromate in sulfuric acid. On average, the humus content in the North Kazakhstan region was 4,6-5,5 %, in the Kostanay region it was 3,3-4,8 %, and in the Akmola region it was 3,2-4,5 %. In the current conditions of agricultural production, the humus balance in the region's arable soils remains negative, indicating a decrease in fertility and the need to replenish it through the application of organic fertilizers and the use of resource-saving agricultural practices for cultivating crops. This requires constant monitoring of the balance values for this indicator.
