FEATURES OF QUALITATIVE PROPERTIES OF SOILS OF KYZYLZHAR DISTRICT OF NORTH KAZAKHSTAN REGION

Soils are the main natural wealth of the North Kazakhstan region, on the basis of which agricultural production is developed. The ecological problem is the reduction of humus content, i.e. the loss of natural soil fertility caused by violations of the biological cycle of substances. In the years of virgin land development and in the subsequent time, not only the best fertile, but also many areas of unproductive land were plowed.
The paper considers the state of arable land, namely the qualitative properties of soils (mechanical composition, acidity, height of humus horizon) of individual rural districts of Kyzylzhar district of North Kazakhstan region. Samples of arable soils were selected on the territory of five rural districts of Kyzylzhar district of North Kazakhstan region. Physical and chemical properties of soils clearly show the state of the soil cover, determine their fertility.
The results of the study showed that the arable soils of most rural districts of Kyzylzhar district are favorable for the cultivation of all crops, do not require special soil improvement, but to preserve fertility it is necessary to make a sufficient amount of organic fertilizers. Soil acidity is mostly neutral, which is suitable for the neutrophilic category of plants. Research will allow purposefully to carry out meliorative actions and use of soils of the territory of the area.
