The article examines the topical issue of humus content in the soils of productive lands and, first of all, especially valuable lands. The dynamics of its change over time over the course of 45 years (from 1967 to 2023) is considered. The dynamics of the humus balance of productive lands is considered using the example of the Belgorod and Pskov regions located in various natural and economic zones of Russian Federation. The lands of these regions differ in soil cover, the structure of agricultural land and the structure of crops on arable land, and, consequently, the indicators of the humus balance, as well as the area of especially valuable lands, also vary. The lands classified as especially valuable productive agricultural lands have high soil fertility and humus content. Especially valuable lands ensure stable yields of cultivated crops, thus supporting food security and food independence of the country. As a result of the study, the indicators of the humus balance dynamics of productive lands and especially valuable agricultural lands were determined for two regions (Belgorod and Pskov). Using the example of the Belgorod region, the costs of maintaining humus content are estimated, conclusions and recommendations are formulated. The authors justify the need to maintain humus balance in productive lands and, particularly in especially valuable agricultural lands, and also propose tools to achieve this goal.
