Abstract. The studies aimed to generalize the results of monitoring the content of mobile forms of sulphur and trace elements in arable soils of the Central Chernozem Region. The work used materials from a continuous agrochemical survey of arable soils in the Belgorod, Voronezh, Kursk, Lipetsk, and Tambov regions. When determining the mobile forms of sulphur and trace elements, we used the methods generally accepted in the agrochemical service. During the period of surveys, as of January 1, 2021, the weighted average content of zinc (except for the Kursk and Tambov regions), manganese (except for the Kursk region), sulphur (except for the Voronezh region), and copper (except for the Belgorod and Tambov regions) decreased in the soils of most regions included in the Central Chernozem Region, whereas the boron content increased. The weighted average content of mobile forms of cobalt in arable soils of the Belgorod and Tambov regions did not change; in the soils of the Voronezh and Kursk regions it decreased. In the Central Chernozem Region, the share of arable soils with a low content of mobile forms of sulphur was 74.7–95.1%, the share of arable soils with a low content of mobile forms of zinc was 99.3–99.9%; the share of arable soils with a low content of mobile forms of copper was 94.3–99.5%; the share of arable soils with a low content of mobile forms of cobalt was 98.3–99.7%. The largest share of soils with a low content of mobile manganese was noted in the Tambov (88.3%) and Kursk (79.7%) regions; the smallest share of soils with a low content of mobile manganese was noted in the Lipetsk (3.1%) and Belgorod (35.6%) regions. In the Belgorod region, the share of arable soils with a high content of mobile forms of boron was 99.2%; in the Lipetsk region it was 92.6%; in the Tambov region it was 93.9%. In the arable land of the Kursk region, the share of soils with a high boron content accounted for 42.7%; the share of soils with a low boron content accounted for 22.1%.
