Reaction of the soil environment of the soils of the regions of Northern Kazakhstan

Abstract

The results of studying the reaction of the soil environment of arable soils in the North Kazakhstan, Kostanay, and Akmola regions for 2020-2023 are presented. Changes in the reaction of the soil environment have been studied. It was found that the pH of the arable soil in the North Kazakhstan region ranged from 7,4 to 8,0, while in the Kostanay region it ranged from 6,8 to 8,6, and in the Akmola region it ranged from 7,4 to 8,0. The maximum pH value in the three regions was 8.3-8.6, indicating that the soil was slightly alkaline. The results of the agrochemical analysis showed that in the North-Kazan and Kostanay regions, farms in the northern and central parts of the regions have maintained soil acidity at a level close to neutral, but there is arable land with a slightly alkaline or alkaline pH. In the Akmola region, there is arable land with a strongly alkaline pH above 8,5.
