The object of the study was the land use area of JSC Agrofirma Rogovatovskaya Niva (a division of Agrofirma Krasnenskaya LLC) in the Belgorod region. The soil cover of the farm is predominantly formed by typical chernozems (40.5% of arable land), leached chernozems (32.0%), and typical carbonate chernozems (22.6%). The results of a continuous agrochemical soil survey conducted in 8 (2008-2012) and 11 (2019-2022) rounds, as well as a soil erosion survey (2016), were used as an information database. Soil samples were collected from the arable horizon and analyzed by an accredited laboratory using standard methods. The analysis revealed that the intensity of mineral fertilizer application increased by 85.5% during the implementation of adaptive landscape farming systems (ALFS), reaching 128 kg/ha. A comparative analysis of the five –year plans showed that over the period 2019-2022, compared with 2008-2012, the average yield increased significantly: winter wheat – by 2.86 t/ha (114.9%), corn (grain) – by 1.09 t/ha (17.8%), soybeans – by 0.51 t/ha (30.0%), barley – by 1.59 t/ha (65.7%), sunflower – by 1.03 t/ha (52.6%). According to the data of agrochemical monitoring from 2009 to 2022, there was an increase in the weighted average values of the indicators: the content of organic matter increased by 0.09%, mobile phosphorus increased by 52 mg/kg, and potassium increased by 20 mg/kg. The content of trace elements also changed: manganese increased by 2.52 mg/kg, zinc increased by 0.32 mg/kg, and copper increased by 0.036 mg/kg. At the same time, there was a tendency to decrease the content of mobile cobalt. No exceeding of maximum permissible concentrations (MPCs) for manganese, zinc, copper, and cobalt was detected.
