RESUMEN:
Los modelos de estimación de erosión son herramientas útiles para la planificación de sistemas productivos sustentables. El modelo Water Erosion Prediction Project (WEPP) estima erosión laminar y en canalículos, así como la carga y deposición del sedimento, con distribución temporal y espacial. Esto permite estimar no sólo los efectos in situ sino también los efectos fuera del sitio, como ser deposición en cauces de agua, pudiéndose aplicar en estudios ambientales. Si bien este modelo está basado en los procesos físicos que ocurren en el suelo, es preciso realizar ajustes sitio-específicos. El objetivo de este estudio fue ajustar el modelo WEPP, para suelos representativos de la zona agrícola litoral oeste y lomadas del este del Uruguay. Se utilizaron datos de parcelas experimentales de escurrimiento de INIA La Estanzuela y Palo a Pique, y se compararon los valores de erosión estimados por WEPP y USLE/RUSLE con los medidos en términos de promedios anuales. Además se contrastó la erosión estimada con WEPP con la medida a escala anual. WEPP estimó la erosión de ambos sitios con alto nivel de precisión, comparable al de USLE (R2=0,97 y 0,98 respectivamente). El índice Nash-Sutcliffe de 0,92 indica que su desempeño es muy bueno. Para continuar esta línea de investigación resulta necesario realizar medidas de variables físicas del suelo o desarrollar ecuaciones de pedotransferencia alternativas.

SUMMARY.
Erosion estimation models are helpful tools for planning sustainable agriculture systems. The model Water Erosion Prediction Project (WEPP) estimates rill and interrill erosion, as well as sediment load and deposition, including temporal and spatial distribution. This enables the estimation of both in-site and off-site effects such as deposition in water bodies, making it useful for environmental studies. Although this model is based on the physical processes that occur in the soil, site-specific adjustments are needed. The aim of this study was to adjust the WEPP model for the representative Uruguayan agriculture soils of the West coast and East rolling plains. We used the data base of the runoff plots from INIA La Estanzuela y Palo a Pique, and we compared erosion values estimated with WEPP and those estimated with USLE/RUSLE, in terms of annual means. In addition, erosion estimated with WEPP was compared with the data measured at an annual scale. WEPP estimated erosion with high precision in both sites, comparable to USLE (R2 =0.97 y 0.98 respectively). A Nash-Sutcliffe value of 0.92 indicates a very good performance. To continue this research line, measures of local soil physical variables or the development of
alternative pedotransfer equations will be needed. MenosRESUMEN:

Abstract: Water erosion can cause irreversible depletions in soil quality and crop productivity. The susceptibility of the soil to erosion is affected by current and historical management practices. Historical soil management practices like ploughing or subsoil loosening may lead to irreversible degradations of soils, which in turn increases soil erosion risk. Six ?Wischmeier? plots under conservation agriculture, but with different historic treatments regarding soil use and management, were evaluated. These plots were installed in 1984 in Colonia del Sacramento, Uruguay on a Vertic Argiudoll. The objective of this study was to quantify how changes in soil quality, generated by different historical soil use and management over the last 35 years, contribute to current runoff and soil erosion in a cropping system under soil conservation practices using no-till, residue retention and cover crops. Considering differences in soil legacy effects of previous land use, plots were grouped in three treatments with contrasting historic index of agricultural intensification (IAI). The IAI was developed combining the duration of land use under agricultural production and the number and intensity of tillage activity resulting in the treatments: tillage with crop-pasture rotation (TIL_CP), no-tillage under several rotations (NT_Mix) and tillage with continuous cropping (TIL_CROP) with an increasing IAI of 3.5, 7.1 and 11.8, respectively. Rainfall events, runoff water and total, fixed and volatile solids were studied from 2017 to 2019. Soil physical (bulk density, penetration resistance, infiltration rate, aggregate stability), chemical (soil organic carbon (SOC), pH, phosphorous (P-Bray)) and biological properties (particulate organic matter (POM), potentially mineralizable nitrogen (PMN)) were assessed in 2019. Yearly average runoff amounted 209, 579 and 320 mm in 2017, 2018 and 2019, respectively. Yearly average soil losses were 233, 805 and 139 kg/ha with significant differences among years. The lowest soil losses were observed in TIL_CP (231, 615 and 146 kg/ha in 2017, 2018 and 2019, respectively) with lowest IAI of 3.5. Infiltration rate was the lowest in plots with highest IAI. Soil bulk density was highest (1.3 g/cm3) in plots with high IAI. SOC and PMN were lowest in TIL_CROP (3.0% SOC and 34 mg/kg PMN), holding the highest IAI of 11.8. Conservation agriculture minimized soil erosion losses in all plots and years, and erosion was much lower than the maximum tolerable threshold of 7,000 kg/ha for this particular soil. However, in historically intensively tilled and cropped soils, soil quality showed long-term adverse effects pointing towards a reduced resilience of the agricultural system.
