    • Adequate vegetative cover decreases nitrous oxide emissions from cattle urine deposited in grazed pastures under rainy season conditions 

      Chirinda, Ngonidzashe; Loaiza, Sandra; Arenas, Laura; Ruiz, Veronica; Faverin, Claudia; Alvarez, Carolina; Savian, Jean Víctor; Belfon, Renaldo; Zuniga, Karen; Morales-Rincon, Luis Alberto; Trujillo, Catalina; Arango, Miguel; Rao, Idupulapati; Arango, Jacobo; Peters, Michael; Barahona, Rolando; Costa, Ciniro; Rosenstock, Todd; Richards, Meryl; Martinez Baron, Deissy; Cardenas, Laura (Nature Publishing, 2019-01-29)
      A decline in pasture productivity is often associated with a reduction in vegetative cover. We hypothesize that nitrogen (N) in urine deposited by grazing cattle on degraded pastures, with low vegetative cover, is highly ...

    • Aporte de la fijación biológica de nitrógeno a la emisión de N2O desde el suelo con cultivo de soja = Contribution of biological nitrogen fixation to N2O emission from soil under soybean 

      Cosentino, Vanina Rosa Noemi; Brutti, Lucrecia Noemi; Civeira, Gabriela; Taboada, Miguel Angel (Asociación Argentina de la Ciencia del Suelo, 2015)
      El óxido nitroso (N2O) es el principal gas de efecto invernadero emitido desde el sector agrícola y su producción biológica en los suelos se genera por dos vías, la nitrificación y la desnitrificación. Recientemente el ...

    • Change of soil carbon storage in monoculture tree plantations across wide environmental gradients: Argentina as a case study 

      Gyenge, Javier; Gatica, Mario Gabriel; Sandoval, Martín; Lupi, Ana Maria; Gaute, Matías; Fernandez, María Elena; Peri, Pablo Luis (Elsevier, 2024-01)
      Forest plantations (through afforestation or reforestation) have been proposed as a valuable option to mitigate carbon (C) emissions. However, high spatiotemporal variation has been observed in soil organic carbon (SOC) ...

    • 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 ...

    • Emisiones de gases de efecto invernadero desde el sector forestal 

      Romaniuk, Romina Ingrid; Cosentino, Vanina Rosa Noemi; Costantini, Alejandro Oscar; Lupi, Ana Maria (Asociación Argentina para el Progreso de las Ciencias, 2018)
      Actualmente, una de las principales estrategias para la mitigación del cambio climático, se basa en el fomento de las prácticas de forestaciónreforestación debido al potencial que estos sistemas presentan para el secuestro ...

    • Emisiones de gases de efecto invernadero en la producción ganadera 

      Costantini, Alejandro Oscar; Perez, Mónica Gabriela; Busto, Mercedes; González, Franco Alexis; Cosentino, Vanina Rosa Noemi; Romaniuk, Romina Ingrid; Taboada, Miguel Angel (Asociación Argentina para el Progreso de las Ciencias, 2018)
      Uno de los impactos ambientales provocados por el sector agropecuario es la emisión de gases de efecto invernadero (GEI). Los principales GEI emitidos desde el sector agropecuario son el dióxido de carbono (CO2), el ...

    • Emisiones de óxido nitroso desde suelos agrícolas y alternativas para mitigarlas 

      Taboada, Miguel Angel; Cosentino, Vanina Rosa Noemi; Costantini, Alejandro Oscar (Asociación Argentina para el Progreso de las Ciencias, 2018)
      El óxido nitroso (N2O) es un gas efecto invernadero con un poder de calentamiento equivalente a 296 veces mayor que el del dióxido de carbono (CO2). El N2O es producido a partir del nitrógeno mineral que entra a los ...

    • Hierarchy of factors driving N2O emissions in non‐tilled soils under different crops 

      Cosentino, Vanina Rosa Noemi; Figueiro Aureggi, Santiago Andres; Taboada, Miguel Angel (Wiley, 2013-10)
      Nitrous oxide (N2O) is emitted to the atmosphere as a by‐product of nitrification and denitrification by soil microbial processes. Differences in climate, soil and management regulate these processes, causing N2O emissions ...

    • 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 ...

    • Methane and nitrous oxide emissions from dung patches deposited by grazing cattle supplemented with maize grain 

      Lombardi, Banira; Alvarado, Patricia Inés; Ricci, Patricia; Guzmán, Sergio Alejandro; Gonda, Horacio Leandro; Juliarena, Maria Paula (Elsevier, 2021-07-13)
      Feeding management represents an opportunity to improve cattle performance in grazing-based production systems and to mitigate emissions of greenhouse gases (GHG) from livestock production. However, it is unclear how diet ...
