Summary. The article presents the results of agrochemical assessment of arable land in agricultural land on the example of Pervomaisky agricultural complex in the Pervomaisky district of Tomsk Region. It has been established that most of arable land is highly humified: the average humus content is 5.1%. Assessment of degree of acidity showed the predominance of slightly acidic soils (about 73% of the farm). Only a tenth of the territory of the farm requires reclamation work - liming. According to the nitrate nitrogen content, the soils under consideration are characterized by a very low and low degree of supply, which indicates a high need for the application of nitrogen fertilizers. A low and medium supply of soils with mobile forms of phosphorus was found. When assessing the content of exchangeable potassium, it was revealed that the soils of the farm are characterized by medium and increased accumulation of it.

Based on the studies conducted, annual application of organic and nitrogen fertilizers can be recommended in order to maintain a deficiency-free balance of humus and mineral nutrition elements. As an alternative to fertilizers, cultivation of green crops is possible. These methods will contribute to the enrichment of soils with organic matter, nitrogen and other elements and will reduce the cost of fertilizers.

Key words: agricultural land, soil, fertility, humus, soil acidity, nitrate nitrogen, mobile phosphorus, exchange potassium.
