Paragenetic associations of elements in soils of agrolandscapes of the Black Sea coast in Russia

Abstract

The results of the study of distribution parameters of a number of elements (Cu, Co, Ni, V, Cr, Ti, Zn, Sn, Pb, Ag, Mo, Ba, Sr, P, Mn) in soils of landscapes of deciduous forests, orchards and vineyards of the Black Sea coast are presented. Geochemical peculiarities of soils of the studied landscapes have been established. The presence of statistically significant interrelations between concentrations of the studied chemical elements in soils of both original natural landscapes and technogenically transformed ones has been revealed. The trend for the increase of a concentration of P, Sr, Cu, Ba, Mn and decrease of V, Cr, Ti in soils of orchards was revealed; in soils of vineyards, it is done for accumulation of P, Sr, Cu, Ba and removal of Mn, V, Cr, Ti. Statistically significant interrelationships between the concentrations of the considered elements (in the soils of deciduous forest, there is Co-Ni, Co-Mn, Zn-Sn; in gardens, there is Ag-Zn, Co-Sn, Ni-Mo, V-Mo, Sn-Ni, Ni-Zn; vineyards contain V-Ti) were revealed, the main paragenetic associations formed in certain landscape-geochemical conditions were determined.
