Evaluation of Quality of Some Well Waters Used in Agricultural Irrigation in terms of Plant Nutrition

In this study, where the suitability of groundwater for irrigation in terms of soil and plants was evaluated, samples were taken from 11 drilling wells used for irrigation in some regions of Kahramanmaraş province. Chemical parameter values such as pH, EC, RSC, SAR, TDS, TH, Na%, PI, SSP, MR, KR, PS were determined in the assessment of irrigation water quality. According to irrigation water quality criteria, all samples except for two samples were in the medium salt/low sodium water (C2S1) class in terms of EC values. TH values were determined as soft water in all well waters. It was determined that the well waters were not suitable for irrigation in terms of plants and soils, including 3 in terms of Na%, SSP, MRI and KR values, 2 for Boron, SAR and RSC values, and one each for pH and PI values. As a result, these wells, which are evaluated problematic for soil and plants in terms of special ionic, salinity and alkalinity, should be used by taking the necessary precautions or should not be used for irrigation.
