A first record of bulk atmospheric deposition patterns of major ions in southern South America
Carnelos, D.A.; Portela, Silvina Isabel; Jobbagy Gampel, Esteban Gabriel; Jackson, R.B.; Di Bella, Carlos Marcelo; Panario, D.; Fagúndez, C.; Piñeiro Guerra, J.M.; Grion, L.; Piñeiro, G. (Springer, 2019-09)Despite the importance of long-term atmospheric deposition of ions for vegetation productivity and biogeochemistry, southern South America lacks long-term deposition records. We report a 6-year-long record of atmospheric ... -
Fertilizer vs. organic matter contributions to nitrogen leaching in cropping systems of the Pampas: 15N application in field lysimeters
Portela, Silvina Isabel; Andriulo, Adrian Enrique; Sasal, Maria Carolina; Mary, Bruno; Jobbagy Gampel, Esteban Gabriel (Springer, 2006-11-07)Nitrogen (N) export from soils to streams and groundwater under the intensifying cropping schemes of the Pampas is modest compared to intensively cultivated basins of Europe and North America; however, a slowNenrichment ... -
Water and nitrate exchange between cultivated ecosystems and groundwater in the Rolling Pampas
Portela, Silvina Isabel; Andriulo, Adrian Enrique; Jobbagy Gampel, Esteban Gabriel; Sasal, Maria Carolina (Elsevier, 2009-12)Understanding nitrogen (N) exchange between cultivated ecosystems and groundwater becomes crucial in the Rolling Pampas where high and variable water table levels are accompanied by increasing N-fertilization rates. Field ...
