    • 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 ...

    • Cover crop species affect N2O emissions at hotspot moments of summer crops 

      Vangeli, Sebastián; Restovich, Silvina Beatriz; Posse Beaulieu, Gabriela (Frontiers Media, 2022-06-01)
      The use of cover crops, combined with low N fertilization and no-tillage, reduces theenvironmental impacts of agriculture. Legume cover crops provide N to the agroecosystem and allow N fertilization to be reduced without ...

    • Effects of fertilizer type on nitrous oxide emission and ammonia volatilization in wheat and maize crops 

      Vangeli, Sebastián; Posse Beaulieu, Gabriela; Beget, Maria Eugenia; Otero Estrada, Edit; Valdettaro, Roció Antonella; Oricchio, Patricio; Kandus, Mariana Virginia; Di Bella, Carlos Marcelo (Wiley, 2022-01-28)
      About half of the applied nitrogen (N) is not consumed by crops, causing environmental and economic costs. This N can be lost as ammonia (NH3) volatilization, nitrous oxide (N2O) emission or leaching, among others. This ...

    • 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 ...

    • Riparian buffer strips influence nitrogen losses as nitrous oxide and leached N from upslope permanent pasture 

      Dlamini, J.C.; Cardenas, L.M.; Tesfamarian, E.H.; Dunn, R.M.; Loick, N.; Charteris, A.F.; Cocciaglia, L.; Vangeli, Sebastián; Blackwell, M.S.A.; Upadhayay, H.R.; Hawkins, J.M.B.; Evans, J.; Collins, A.L. (Elsevier, 2022-05-23)
      Riparian buffer strips can have a significant role in reducing nitrogen (N) transfers from agricultural land to freshwater primarily via denitrification and plant uptake processes, but an unintended trade-off can be elevated ...
