Assessment of irrigation water quality from Jalkot tahsil of Latur district

All water samples were slightly saline having average pH 7.54 in May and 7.36 in October. Average EC was 0.728 and 0.576 dSm⁻¹ in May and October, respectively. The EC of water samples were high in the month of May. Na⁺ content in water ranged from 1.00 to 11.27 meL⁻¹ during May while in winter it was from 0.50 to 9.68 meL⁻¹. Among all samples, Na⁺ and Cl were dominant in water. The relative proportion of cations in irrigation water were Na⁺ > Mg⁺⁺ > Ca⁺⁺> K⁺. In summer K⁺ ranged from 0.03 to 1.5 meL⁻¹, Ca⁺⁺ from 0.8 to 6.5 meL⁻¹ and Mg⁺⁺ from 0.2 to 7.0 meL⁻¹. The CO₃⁻ content ranged from 0 to 2.2 meL⁻¹ with an average value of 0.776 meL¹
