[ES] La puesta en marcha del nuevo regadío de Quinto (Zaragoza) brindó la oportunidad de estudiar su salinidad inicial. Los muestreos indican que tanto en suelos como en freáticos y efluentes hay saturación de calcio y abundancia de sulfato y magnesio. Los elevados contenidos de yeso reducen la utilidad del extracto 1:5 suelo:agua, que puede completar- se mediante el ensayo con acetona en el propio extracto. Al mismo tiempo se estableció una metodología de seguimiento de la salinidad edáfica, mediante lecturas in situ con un instrumento portátil. Se calibró un sensor electromagnético (SEM) hasta varias profundidades para medida de salinidad edáfica. Los resultados son correctos pese a las desfavorables condiciones por la presencia de calizas someras impenetrables con barrena, abundantes suelos con horizonte de yeso, y contenidos de humedad desiguales a lo largo del polígono. El SEM presenta limitaciones en el intervalo de baja salinidad, que podrán evaluarse en detalle si se dispone de sondeos más profundos.
[EN] Development of the new irrigation distric of Quinto (Zaragoza) affords the opportunity to characterize the initial salinity status of the soils within this district. Analyses of samples from soils, water tables and effluents indicate high concentrations of calcium, sulphate and magnesium. Horizons of pure gypsum are common, making the soil:water extract 1:5 unsuitable to assess soil salinity; an acetone assay using the same extract is proposed. Moreover, a method has been developed for monitoring soil salinity, in situ, using a hand-held electromagnetic sensor (SEM). The SEM was calibrated for several soil depths in order to predict soil salinity results were right despite the unfavourable soil conditions such as shallow auger-impenetrable limestone beds, gypsum horizons, and variable soilwater contents. Limitations in the SEM precision become important in the lower saliniiy range and should be evaluated when deeper sampling in feasible.
