MORPHOLOGICAL CHARACTERISTIC AND PHYSICO-CHEMICAL PROPERTIES OF ARABLE SOILS OF KARABALYK DISTRICT OF KOSTANAY REGION

Abstract

In the process of production activities, a human influences natural factors of soil formation and soils leading to changes in their initial properties. The change in the morphological profile, fertility, and various soil properties depends on agricultural use and the duration of its impact, in some cases determines the adverse effects on the soil. Intensive load on the soil during agricultural exploitation results in depletion of plant nutrition reserves, reduction of humus content, deterioration of soil properties compared to virgin analogues. The article presents the morphological and physico-chemical properties of arable soils widespread in the Karabalyk district of Kostanay region. The research results have shown that agricultural exploitation of soils affects the decrease in the thickness of the A+B1 horizon, changes in the humus content, the amount of absorbed bases, destruction of the structure and an increase in the amount of carbonates in the soil profile due to annual treatments, overconsolidation of soil and other.
