Abstract

The increasing pressures of agricultural development surfaces on water resources availability of Katiola area obliged farmers to the use groundwater for food crops irrigation. However, groundwater used for irrigation makes an impact on soil quality. The aim of this study is to estimate the capability of Katiola area ground waters to irrigate food crops by using an approach based on Sodium Absorption Ratio (SAR) and Permeability Index (PI). The results show that most of the groundwater samples (67%) in the study area are suitable for irrigation, except few points located in south-east.
