The influence of irrigated water from the South-Bug irrigation system
(Mykolayiv district, Mykolayiv region) on chemical indicators of soil quality is
investigated in the paper. The study revealed a significant deterioration of
agrochemical characteristics of the soil, in particular: a significant accumulation in
the soil profile of sodium and magnesium ions and a significant decrease in calcium,
which indicates about its leaching; significant growth of chloride and bicarbonate
ions. A change in the chemical parameters of the soil indicates at a change in the
chemistry of soil salinization from sulfate-calcium to bicarbonate-sodium and
intensification of the salinization process under the influence of mineralized waters
from the South Bug irrigation system. It was found the increased of toxic salts and the
total content of toxic salts 2.5 times under irrigation conditions.
