AbstractThe development of a decision support system (DSS) based on SALTIRSOIL for the precise management of irrigation water, crop and soil in agricultural lands under risk of salinization, sodification and alkalinization needed SALTIRSOIL to be able to calculate soil salinity, sodicity and alkalinity at monthly intervals. The new monthly SALTIRSOIL model has been developed and validated in three citrus orchards in the Almenara irrigitation area in Valencia (Spain). Comparison of simulations and measurements of electrical conductivity and sodium adsorption ratio in the saturation extract and pH in the saturated paste indicated the SALTIRSOIL is able to give reliable predictions of soil salinity, sodicity and alkalinity when the soil drainage is not impeded. Furthermore, the SALTIRSOIL model gives these reliable predictions in a cost-effective way because only a few basic water quality, climate, soil, crop and irrigation management information data are required to run the model.
