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

      Posse Beaulieu, Gabriela; Richter, Klaus; Lewczuk, Nuria Andrea; Cristiano, Maria Piedad; 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 and water vapor balance in a subtropical pine plantation 

      Posse Beaulieu, Gabriela; Lewczuk, Nuria; Richter, Klaus; Cristiano, Piedad María (2016-10)
      Afforestation has been proposed as an effective tool for protecting primary and/or secondary forests and for mitigating atmospheric CO2. However, the dynamics of primary productivity differs between plantations and natural ...
    • 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 ...
    • Drivers of N2O emissions from natural forests and grasslands differ in space and time 

      Araujo, Patricia Ines; Piñeiro Guerra, Juan Manuel; Yahdjian, L.; 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 ...
    • 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 ...
    • MAGGnet : an international network to foster mitigation of agricultural greehouse gases 

      Lewczuk, Nuria; Posse Beaulieu, Gabriela; Liebig, M.A.; Franzluebbers, A.J.; Alvarez, Carolina; Chiesa, Tomás Della; Piñeiro, Gervasio; Yahdjian, María Laura; Grace, P.; Cabral, Osvaldo Machado Rodrigues; Martin-Neto, Ladislau; Rodrigues, Renato de Aragao Ribeiro; Amiro, B.; Angers, D.; Hao, X.; Oelbermann, M.; Tenuta, M.; Munkholm, L.J.; Regina, K.; Cellier, Pierre; Ehrhardt, Fiona; Richard, G.; Dechow, R.; Agus, F.; Widiarta, N.; Spink, J.; Berti, Antonio; Grignani, Carlo; Mazzoncini, Marco; Orsini, Roberto; Roggero, Pier Paolo; Seddaiu, Giovanna; Tei, Francesco; Ventrella, Domenico; Vitali, Giuliano; Kishimoto-Mo, A.; Shirato, Y.; Sudo, S.; Shin, J.; Schipper, L.; Savé, Robert; Leifeld, J.; Spadavecchia, L.; Yeluripati, J.; Del Grosso, Stephen J.; Rice, Charles W.; Sawchik, Jorge (2016)
      Research networks provide a framework for review, synthesis and systematic testing of theories by multiple scientists across international borders critical for addressing global-scale issues. In 2012, a GHG research network ...
    • Water productivity in soybean following a cover crop in a humid environment 

      Alfonso, Carla Susana; Barbieri, Pablo; Hernandez, Mariano Daniel; Lewczuk, Nuria; Martinez, Juan Pablo; Echarte, María Mercedes; Echarte, Laura (Elsevier, 2020-02-05)
      We evaluated the influence of the termination dates of a winter cover crop on (i) soil water availability during soybean (Glycine max L. (Merr)) growing season, (ii) soybean evapotranspiration (ET) and iii) water productivity ...
