The agrochemical composition of the soils of the Kostanay region is a study based on the results of the agrochemical laboratory Agro Lab for the period from 2020 to 2023. The study provides data on the regional soils, their types, properties, fertility, chemical composition, and the dependence of fertility on the content of nutrients. The results of the study showed that restoring the balance between plant nutrient requirements and soil fertility - namely, between the amount of fertilizer applied and the soil’s capacity to regenerate its fertility - represents a major challenge, the resolution of which is crucial for the sustainable development of crop production and agriculture as a whole. Such a nominal balance enables the supply of nutrients to plants while preserving fertility and enhancing the soil’s physical, mechanical, and biological properties. It has been proven that the systematic and scientifically grounded application of mineral and organic fertilizers increases crop yields, improves the quality of agricultural products, contributes to the gradual restoration of soil fertility, and helps preserve ecology and protect the environment. The maximum weighted average organic matter content (5.17%) was recorded in the arable soils of the Kostanay region in the Karabalyk region and the minimum (1.98%) was recorded in the Amangeldy region. The highest content of mobile forms of P2O5 (36-37 mg/kg) was observed in the soils of the Karabalyk district and the B.Mailin district. The reaction of the soil environment from 7.1 (Karabalyk district) and 8.6 (Amangeldy district) was recorded in the soils of arable land. The arable soils of the region are mainly characterized by low availability of mobile forms of phosphorus and sulfur. The study is intended for all those engaged in crop cultivation who are concerned about the condition of arable land and the quality of the harvest. It can serve as a guide for the balanced and optimal application of mineral fertilizers.
