Abstract
One of the most pressing problems in the North Kazakhstan region is the deterioration of soil retention properties due to climatic changes, soil intolerance to dry climatic conditions and a decrease in crop productivity. In this article, to study the effect of biochar on improving the physical properties of leached chernozem soils in the North Kazakhstan region, biofertilizer biochar was introduced in different quantities. The physical properties of arable land, virgin land and soils in which biochar was introduced, used in agriculture for more than 30 years, have been studied in comparison. The dry spring climate of recent years has a significant impact on the decline in crop yields in the North Kazakhstan region.
