The zonal soils of the West Kazakhstan region are chestnut soils. These soils serve as the main substrate for the cultivation of key agricultural crops, including cereals, vegetables, fruit, berries, forage, melons, and others, and are also used as pasture and hayfields. Therefore, the study of soil fertility, their 116properties, and agrochemical indicators has been and remains one of the most relevant issues in the dry steppe zone. The processing of obtained data and the acquisition of reliable results are impossible without the application of computer technologiesIn recent years, soil surveys have been conducted in a digital format. Almost all soils in Kazakhstan have been digitized. The results of the analyses are processed on various programs. The soil analysis results were statistically processed using analysis of variance. The analysis revealed that the relationship between the gross forms of potassium and humus is direct and strong. The amount of gross potassium is influenced by the humus content. The regression model is reliable and adequate; it confirms the validity of the quantitative dependence between the content of gross forms of potassium and humus. As the humus content in the soil increases, the content of gross forms of potassium increases. The calculated t-value from Student’s t-test for the coefficients α and b, with t fact > t table, was found to be statistically significant, leading to the conclusion that humus has a significant effect on the content of gross potassium. The correlation-regression analysis between water-soluble potassium and humus also demonstrated a dependency between water-soluble potassium and humus
