Drivers of N2O emissions from natural forests and grasslands differ in space and time
Araujo, Patricia Ines; Piñeiro Guerra, Juan Manuel; Yahdjian, Laura; Acreche, Martin Moises; Alvarez, Carolina; Alvarez, C.R.; Costantini, Alejandro Oscar; Chalco Vera, Jorge Elías; De Tellería, J.M.; Della Chiesa, T.; Lewczuk, Nuria; Petrasek, M.; Piccinetti, Carlos Fabian; Picone, Liliana; Portela, Silvina Isabel; Seijo, Sebastian; Videla, Cecilia; Piñeiro, G. (Springer, 2020-06-30)Understanding the drivers of greenhouse gas (GHG) emissions is one of the most critical global environmental challenges to mitigate the increasing global temperature. Nitrous oxide (N2O) emissions are highly variable in ... -
Higher than expected N2O emissions from soybean crops in the Pampas Region of Argentina: Estimates from DayCent simulations and field measurements
Della Chiesa, Tomas; Piñeiro, Gervasio; Del Grosso, Stephen J.; Parton, William J.; Araujo, Patricia Ines; Yahdjian, Laura (Elsevier, 2022-08)In developing countries, agriculture generally represents a large fraction of GHG emissions reported in National Inventories, and emissions are typically estimated using Tier 1 IPCC guidelines. However, field data and ... -
Metal cation concentrations improve understanding of controls on soil organic carbon across a precipitation by vegetation gradient in the Patagonian Andes
Hodges, Caitlin; Araujo, Patricia Ines; Hess, Laura J.T.; Vivanco, Lucía; Kaye, Jason; Austin, Amy T. (Elsevier, 2023-12)Tephra-derived soils retain more organic carbon (C) than soils formed from any other parent material, but this C may be sensitive to changes in climate and land use. Here we evaluate the effects of precipitation, temperature, ... -

Portela, Silvina Isabel; Torti, Maria Juliana; Garbini, Dalila J.; Cabrini, Silvina María; Araujo, Patricia Ines; Restovich, Silvina Beatriz (2018-09)El manejo de las excretas y el agua es fundamental en la sustentabilidad ambiental de los sistemas de producción de leche. El vertido de efluentes crudos o deficientemente tratados a cursos de agua o al suelo es frecuente ... -
Pesticides detected in surface and groundwater from agroecosystems in the Pampas region of Argentina: occurrence and ecological risk assessment
Vera Candioti, Josefina; Araujo, Patricia Ines; Huerga, Ignacio Roberto; Rojas, Dante Emanuel; Cristos, Diego Sebastian; Malmantile, Alberto (Springer, 2021-10-02)The objective of this study was to evaluate the occurrence of pesticides in surface and groundwater of agricultural areas of the Pampas region of Argentina and to develop an ecological risk assessment (ERA) of pesticides ... -
Reutilizar purines de tambo como oportunidad para reciclar nitrógeno y reducir su impacto ambiental
Portela, Silvina Isabel; Araujo, Patricia Ines; Restovich, Silvina Beatriz; Della Chiesa, Tomás; Ponsa, Juliana M.; Peña Ballesteros, Andrea (Asociación Argentina de Ecología, 2023-08)Los purines de tambo (excretas mezcladas con agua de las instalaciones de ordeñe) se pueden reutilizar en la producción agrícola como reemplazo de los fertilizantes sintéticos. Sin embargo, su alta concentración nitrogenada ...
