SALTMED is a generic-type model suitable for application over a variety of irrigation systems, soil types, soil stratifications, crops and trees, water application strategies (blending or cyclic), leaching requirements and water qualities (fresh or saline). The model employs well-established and physically based water and solute transport, evapotranspiration and crop water uptake equations. It was run with several examples of applications using data from the literature, and in all cases successfully illustrated the effect of the irrigation system, the soil type, the irrigation salinity level on soil moisture and salinity distribution, leaching requirements, and crop yield. The paper describes successful tests that used field data from tomato crops grown in Syria and Egypt over five seasons (2000-2002).
