    • Attribution of carbon dioxide fluxes to crop types in a heterogeneous agricultural landscape of Argentina 

      Posse Beaulieu, Gabriela; Richter, Klaus; Lewczuk, Nuria Andrea; Cristiano, Piedad Maria; Gattinoni, Natalia Noemí; Rebella, Cesar Manuel; Achkar, Antonio (Springer, 2014-10)
      The increasing proportion of agricultural lands worldwide makes it necessary to intensify the research concerning the carbon exchange at agricultural sites. In order to determine the Net Ecosystem Exchange (NEE) in an ...

    • Carbon dioxide fluxes on a soybean field in Argentina: influence of crop growth stages 

      Posse Beaulieu, Gabriela; Richter, Klaus; Corin, Jorgelina Mariana; Lewczuk, Nuria Andrea; Achkar, Antonio; Rebella, Cesar Manuel (Bentham Open, 2010)
      CO2 fluxes were measured in a soybean field in the Province of Buenos Aires, Argentina, with an eddy covariance system consisting of a CO2/H2O infrared gas analyzer and a sonic anemometer. The measurements were carried out ...

    • CO2 and N2O flux balance on soybean fields during growth and fallow periods in the Argentine Pampas—A study case 

      Lewczuk, Nuria Andrea; Posse Beaulieu, Gabriela; Richter, Klaus; Achkar, Antonio (Elsevier, 2017-06)
      The estimation of the GHG balance of agroecosystems is essential to evaluate the impact of agriculture on the composition of the atmosphere. Cultivated soils may act as a sink or a source of CO2 and usually emit N2O. The ...

    • Impact of land use during winter on the balance of greenhouse gases 

      Posse Beaulieu, Gabriela; Lewczuk, Nuria Andrea; Di Bella, Carlos Marcelo; Richter, Klaus; Oricchio, Patricio; Hilbert, Jorge Antonio (Wiley, 2018)
      The increase in atmospheric greenhouse gases (GHGs) can be mitigated by capturing CO2 from the atmosphere and/or by reducing their emissions. Replacing winter intercrop fallow by cover crops (CCs) can sequester carbon and ...

    • Patterns and controls of carbon dioxide and water vapor fluxes in a dry forest of central Argentina 

      Garcia, Alfredo Gabriel; Di Bella, Carlos Marcelo; Houspanossian, Javier; Magliano, Patricio Nicolás; Jobbagy Gampel, Esteban Gabriel; Posse Beaulieu, Gabriela; Fernandez, Roberto J.; Nosetto, Marcelo Daniel (Elsevier, 2017-12)
      Covering 16% of global land surface, dry forests play a key role in the global carbon budget. The Southern Hemisphere still preserves a high proportion of its native dry forest cover, but deforestation rates have increased ...
