ABSTRACT

The chemical composition of rainfall over the territory of Northern Kazakhstan – the main agricultural region of the Republic is analyzed. On average for a year, precipitation belongs in neutral type, however for the vegetative period the relation of acid-forming anions to neutralized cautions in most cases is less than one, i.e. predisposition to acidification is observed. The amount of the sulfur, which is dropping out per unit area, is considerable. On the most part of the considered territory, it several times exceeds the norms, which are considered as admissible.

Keywords: Northern Kazakhstan, pollutants, hydrogen indicator, sulfates, vegetative period, dynamics of pollutants.
