Assessment Of Salinity And Sodicity Of Water Used For Irrigation In Three Sub-catchments In The Upper Athi River Basin, Kenya

ABSTRACT The erratic pattern of rainfall over the years coupled with increasing population has left no option but to cultivate more farmlands through irrigation to meet food demand. Irrigated Agriculture as essential as it is if not done with care through good practices and use of quality water can lead to soil salinization and ecological unsustainability. In Kenya a lot of irrigated lands have been abandoned after few years of cultivation due to salinization. This study was carried out to assess the salinity and sodicity in water used for irrigation in three sub catchments in the Upper Athi …
