Sodium adsorption ratio (SAR) of the soil is needed to quantify the amount of amendments. The objective of this study was to evaluate the performance of Adaptive Neuro Fuzzy Inference System (ANFIS) for estimating the SAR of the soil. In this research, 153 observations of soil properties were Original Research Article
