Abstract. The study investigated the agrochemical properties of the soils of the Gobustan region, located in the northeastern part of the Greater Caucasus. Effective use of fertilizers requires studying the specific characteristics of individual soil types and the amount of nutrients that can be absorbed in these soils. Therefore, before we started the experiment, we took soil samples from the gray-brown (chestnut) soils of the Gobustan region in order to study their agrochemical properties and determined the amount of nutrients absorbed in the laboratory. The results of the research on the mountain gray-brown (chestnut) soils studied under wheat show that the soils are weakly and moderately humified and have a neutral to slightly alkaline soil reaction. Ammonium nitrogen (NH₄-N), exchangeable potassium, and mobile phosphorus were studied, and scientifically substantiated agrochemical and agrotechnical measures were proposed in accordance with the existing indicators.
