It was determined that beginning from 1990s increase happened in temperature and amount of the precipitations significantly reduced. These climate changes affected the quantitative indicators of the Kur water. The ion content of the river water considerably rose in 2018 in comparison with 1952 and 1990s. This rise was more intensive towards the river mouth. In 1952 the ion sum in the Girag Kasaman station was 419,0 mg|l, but in 1990 this figure was 608,3 mg|l, in 2018 it was 620,5 mg|l. But in Banka near the river mouth a quantity of ions was 865,0 mg|l in 1952, 874,7 mg|l in 1990, but it was 888,1 mg|l in 2018. The climate alteration affected mineralogical composition and amount of biogenic elements. A quantity of minerals legally rose while approaching the river mouth. Especially this increase has risen even further for 30 years.Change of the Kur water quality in this direction causes formation of some problems in irrigation use. Tons of harmful salts enter every hectare of land. The undrained and old unrepaired drained soil are salinized and create condition for degradation.
