“…However, an approach that focused upon soil salinity contour lines would not make sense for broad areas of this district, which encompasses contrasting soils and thousands of irrigated plots with different soils, crops, management, and irrigation timing. For these conditions, we mapped soil salinity phases using EMI (Nogués et al, 2006) which produced a map useful for upgrading the irrigation system (Herrero et al, 2007). All these work regress 80 the soil electrical conductivity determined from saturation paste extracts (ECe) on the EM38 readings to convert the EMI data into soil salinity.…”

Soil salinity encroachment is an increasing concern in many irrigated lands, because of the undesirable effects of soluble salts on agricultural production and on water quality. From this point of 10 view, the design and management of irrigation districts can be evaluated by monitoring the soil salinity.There are few cases in the world where comparisons can be undertaken from 'historic' data sets for extents other than individual plots. We demonstrate a monitoring procedure using electromagnetic induction (EMI) survey in an irrigated district in Spain. This district is the only one having an established soil salinity baseline. The EMI data acquired at the same plots were converted to soil 15 electrical conductivity by calibrating with augered soil samples. The presented calibrations improve the baseline for future comparisons and for the treatment and understanding of new acquisitions of field data in next surveys. A shortcoming inherent to destructive soil sampling is its potential for biasing effects on long-term monitoring of soil salinity by means of GPS or other means of accurate localization and relocalization of soil sampling, the herein called "localization paradox", rarely treated 20 in scientific papers. The localization paradox is relevant for any variable soil property requiring repeated sampling. This issue is discussed, and a way for its overcoming by using EMI readings displaced from the augering is presented. EMI needs calibration with a reduced number of soil samples analyzed in the lab. The adoption of our data treatment procedures will facilitate soil salinity monitoring. 25

“…Soil Series in the soil map of Barbués and Torres de Barbués, with their classification, extent, and typic pedon (Nogués, 2002 the area has low (64-107 mm) or very low (< 64 mm) available water retention capacities and mainly correspond to soils with moderately coarse textures (65% of area with very low AWHC) though low capacities are also found in moderately fine-textured soils (51% of area with low AWHC). Soils with low irrigation efficiency (Herrero et al, 2007) correspond to platforms and are suitable for changing the irrigation system into sprinkle irrigation. Thirty-three percent of the study area has high to very high available water retention capacities and these soils also have a high efficiency of flood irrigation.…”

“…The map of AWHC was obtained for a soil depth of 1.5 m for the 27 soil Series (Herrero et al, 2007). The five classes established on the map correspond to AWHC data ranging from very low (< 64 mm) to very high (> 250 mm) and follow the classes established by Soil Conservation Service (1983).…”

“…Enhancing decision-making is one of the key purposes of soil surveys (Arnold, 2016) and the utility (or success) of a soil map is determined by its final users. Herrero, Robinson, and Nogués (2007) derived from the soil map a suitability map for (1) standard frequency sprinkling; (2) highfrequency sprinkling; and (3) flood irrigation. This would be the map for decision-makers and irrigators concerned with upgrading irrigation systems.…”

Irrigation is needed for profitable agriculture in the central Ebro valley, one of the driest regions in Europe. In this region, aridity and outcrops of saliferous strata induce soil salinity in some irrigated districts. We present a soil map of two municipalities (about 32 km 2 ) coping with soil salinity and currently changing their irrigation from flood to pressurized systems. The 1:25,000 scale map displays 27 Soil Series following the Soil Taxonomy approach and records local pedodiversity for the first time. The scale of the map and its delineation on orthophotographs enables users to locate each agricultural plot (typical size ∼1 ha) and to assign the soil information relevant for irrigation, and then a Soil Phase for salinity. Saline soils occur in irrigated areas totaling 24% of the total surface of the two municipalities studied. The salinity mapping plus other soil features used for map unit definition (texture, stoniness, and available water holding capacity), allow recommendations about the design of irrigation system enhancements.

Abstract. This paper addresses the following points: how can whole soil data from normally available soil mapping databases (both conventional and those integrated by digital soil mapping procedures) be usefully employed in hydrology? Answering this question requires a detailed knowledge of the quality and quantity of information embedded in and behind a soil map.To this end a description of the process of drafting soil maps was prepared (which is included in Appendix A of this paper). Then a detailed screening of content and availability of soil maps and database was performed, with the objective of an analytical evaluation of the potential and the limitations of soil data obtained through soil surveys and soil mapping. Then we reclassified the soil features according to their direct, indirect or low hydrologic relevance. During this phase, we also included information regarding whether this data was obtained by qualitative, semi-quantitative or quantitative methods. The analysis was performed according to two main points of concern: (i) the hydrological interpretation of the soil data and (ii) the quality of the estimate or measurement of the soil feature.The interaction between pedology and hydrology processes representation was developed through the following Italian case studies with different hydropedological inputs: (i) comparative land evaluation models, by means of an exhaustive itinerary from simple to complex modelling applications depending on soil data availability, (ii) mapping of Correspondence to: G. Langella (glangella@unina.it) soil hydrological behaviour for irrigation management at the district scale, where the main hydropedological input was the application of calibrated pedo-transfer functions and the Hydrological Function Unit concept, and (iii) flood event simulation in an ungauged basin, with the functional aggregation of different soil units for a simplified soil pattern.In conclusion, we show that special care is required in handling data from soil databases if full potential is to be achieved. Further, all the case studies agree on the appropriate degree of complexity of the soil hydrological model to be applied. We also emphasise that effective interaction between pedology and hydrology to address landscape hydrology requires (i) greater awareness of the hydrological community about the type of soil information behind a soil map or a soil database, (ii) the development of a better quantitative framework by the pedological community for evaluating hydrological features, and (iii) quantitative information on soil spatial variability.
