Monitoring the content of manganese, zinc, and cobalt in Haplic Chernozem

The paper uses the materials of local agroecological monitoring of arable soils of the Belgorod region on the content of manganese, zinc, and cobalt in haplic chernozem of the steppe part of the Belgorod region. The content of manganese, zinc and cobalt in the arable horizon was 1.42, 1.22 and 1.23 times higher than in the parent rock, respectively. A strong correlation was established between the total contents of zinc and cobalt in the soil profile (r=0.77), and the bonds of manganese with zinc and cobalt had the strength of an average value (r=0.59 and r=0.55). The content of mobile forms of the studied trace elements in haplic chernozem is at a low level. The main reason for the shortage of mobile forms of manganese, zinc and cobalt is their low background content in virgin soil.
