Abstract :

In order to use groundwater for agriculture, qualitative studies should be carried out. One of the most commonly used methods for evaluating is Wilcox method. In this research, the quality of groundwater of Golgir plain was investigated using 10 village wells for agricultural use with Wilcox chart. The EC and SAR parameters were evaluated and the samples were transferred to the Wilcox chart. The results showed that all specimens were placed on the C2S1 floor, which are in a small salinity range suitable for farming, so there is no limit to use in agriculture. Also, spatial mapping of EC and SAR parameters was provided by kriging geostatistical grounding method. The results showed that due to low parameters of parameters, there is no specific pattern in spatial changes and there is no need for special management and action, and underground water is the whole range that can be used in agriculture.
