40 ground water samples of 10 villages in Surat district, Gujarat (India) were analyzed for their suitability for irrigation purpose. The mean values of 4 samples taken from each village have been reported in the present study. Ground water of the study area was classified according to sodium adsorption ratio (SAR), percentage sodium (PS), residual sodium carbonate (RSC), Kelley's ratio and electrical conductivity. The value of sodium adsorption ratio indicated that majority of samples (9 out of 10) fall in low sodium hazard category. As per classification made by Wilcox (1948), on the basis of percentage sodium and electrical conductivity, only 1 sample (Vesu) not found suitable for irrigation purpose while only 1 sample (Gaviyar) found in good category. The remaining 8 samples were in good to permissible and permissible to doubtful category. Ground water was also classified according to the classification of United States Salinity Laboratory based on sodium and salinity hazard.
对印度古吉拉特邦苏拉特地区10个村庄的40份地下水样本进行了分析，以评估其灌溉适用性。本研究报告了从每个村庄采集的4份样本的平均值。根据钠吸附率（SAR）、钠百分比（PS）、残留碳酸钠（RSC）、凯利比率和电导率对研究区域的地下水进行了分类。钠吸附率的值表明，大多数样本（10个中的9个）属于低钠危害类别。根据威尔科克斯（1948年）基于钠百分比和电导率的分类，只有1个样本（韦苏）不适合灌溉，而只有1个样本（加维亚尔）属于良好类别。其余8个样本处于良好到允许以及允许到可疑类别。还根据美国盐度实验室基于钠和盐度危害的分类对地下水进行了分类。
