BUSCADOR RECOLECTA

Conjunto de datos de los experimentos origen del citado artículo, This study compares the distribution of bulk soil organic carbon (SOC), its fractions (unprotected and physically, chemically, and biochemically protected), available phosphorusCE1 (Pavail TS4), organic nitrogen(Norg), and stable isotope ( 15N and 13C) signatures at four soil depths (0–10, 10–20, 20–30, and 30–40 cm) between a nearby open forest reference area and a historical olive orchard (established in 1856) located in southern Spain. In addition, these soil properties, as well as water stable aggregates (Wsagg), were contrasted at eroding and deposition areas within the olive orchard, previously determined using 137Cs. SOC stock in the olive orchard (about 40 t C ha1) was only 25% of that in the forested area (about 160 tC ha1) in the upper 40 cm of soil, and the reduction was especially severe in the unprotected organic carbon. The reference and the orchard soils also showed significant differences in the 13C and 15N signals, likely due to the different vegetation composition and N dynamics in both areas. Soil properties along a catena, from erosion to deposition areas within the old olive orchard, showed large differences. Soil Corg, Pavail and Norg content, and 15N at the deposition were significantly higher than those of the erosion area, defining two distinct areas with a different soil quality status. These overall results indicate that the proper understanding of Corg content and soil quality in olive orchards requires the consideration of the spatial variability induced by erosion–deposition processes for a convenient appraisal at the farm scale., Spanish Ministry of Economy and Competitiveness (grant no.

Data corresponding to the calibration and validation of overland flow detectors presented in in paper "Autonomous shallow flow runoff detector for hillslope hydrological studies".-- Datos de calibración y validación de detectores de escorrentía presentados en el artículo "Autonomous shallow flow runoff detector for hillslope hydrological studies"., This is the underlaying data for the manuscript which describes the development, calibration and validation of an autonomous overland flow detector (OFD) for the measurement and recording of shallow runoff depth at varying recording intervals based on measurement of runoff water electrical conductivity (EC). Using electronic components easily available and of moderate cost, approximately367€ per unit, the proposed device can operate for a broad range of surface overland flow with EC from 0 to 435 µS cm-1 with a regular charge using a small built-in cell panel. It was originally intended for use in experiments related to runoff connectivity and efficiency of vegetated buffer strips at hillslope scale. Results show how, once calibrated for the expected range of runoff EC, the proposed device can provide reliable and replicable measurements among different units with an average root mean square error of 3mm. When deployed in the validation test under rainfall simulation with water of high EC (435 µS cm-1)it allowed the determination of the evolution of the change in runoff starting time and the duration of the hydrograph after the end of rainfall in individual points as a function of slope length. In this test the differences in depth among OFD was not significant, since being lower than 4 mm overlaps with the average measurement error among units. This result highlights the need for careful interpretation of the measured depth in relation to the equipment measurement error in spatial variability of shallow flow. Further improvements will concentrate on remote communication for downloading data via a cell phone network, and additional ruggedness and autonomy for long-term deployment in the field under very cloudy conditions., AGL2015-65036-C3-1-R (Spanish Government), Peer reviewed
