Answer 2

• Chemically, the black soils are rich in lime, iron, magnesia and alumina. They also contain potash

• The composition of the microelements in the alluvial soils is mainly determined by the composition of the microelements in the bottom sediments. The alluvial soils are somewhat enriched in Mn, Zn, Co, and Cu, which is related to the biological accumulation of these elements entering the trophic chains.
