Highlighting twenty years of salinity research in Spain’s Ebro River Basin

Abstract

• Terrestrial EM vehicles are excellent tools for soil salinity mapping and establishment of relationships with hydrology and water quality. • Soil and water salinity is and will continue to be an increasing problem in the ERB. • Our irrigation waters are of good quality for crops. Thus, high irrigation efficiencies are attainable in order to minimize salt loading in IRF. • Our irrigation waters may impair losses in the structural stability of sensitive (silt) soils. Ranking by measuring IR with gypsum-saturated, distilled and canal irrigation waters.

• TLS and DIS are excellent tools for appraisal of salinity tolerance of crops under field conditions. • Strategies to reduce leaf salt absorption in saline sprinkler irrigation: - 3-min pre-wetting and 3-min post-washing with fresh water is a recommended strategy in barley and corn. - Nocturnal irrigations did not have any beneficial effect over diurnal irrigations in alfalfa and corn.
