The main objective of this study was to determine the effect of the quality of irrigation water currently used in various agricultural demand units (ADU) on the soil-water salinity, assessing the effects of its use on crop yields and soils agronomic properties. The current state of the water quality used in all ADUs of the Segura Basin (Spain) was identified through sampling points located in surface and groundwater bodies. The geographical relationship established between water quality and crops in each ADU allowed a prospective analysis of the major agronomic risks of salinity, infiltration, toxicity by undesirable ions and the resulting environmental risks of soil degradation. WATSUIT software was used for each existing relationship between water bodies and ADUs. The results of this study provide geo-referenced knowledge of the current status of water quality and of the problems that its use may cause on the crops and the environment. It is also the starting point in establishing actions to increase the quality of irrigation water improving environmental conservation.
