    • 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 ...

    • Crop intensification with sustainable practices did not increase N2O emissions 

      Casanave Ponti, Sheila Mailén; Videla, Cecilia; Monterubbianesi, María Gloria; Andrade, Fernando Hector; Rizzalli, Roberto Héctor (Elsevier, 2020-04-15)
      Nitrous oxide (N2O) is the most important greenhouse gas produced by agricultural soils and is a byproduct of microbial nitrification and denitrification processes. The N2O emission rates depend on soil, climatic ...

    • Increases in nitrogen use efficiency decrease nitrous oxide emissions but can penalize yield in sugarcane 

      Chalco Vera, Jorge Elías; Portocarrero, Rocio; Piñeiro, Gervasio; Acreche, Martin Moises (Springer, 2021-11)
      Nitrogen (N) fertilization strategies focused on increasing nitrogen use efficiency (NUE) and decreasing nitrous oxide (N2O) emissions are important for sustainable crop production. In sugarcane, however, a joint assessment ...

    • 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 ...

    • 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 ...

    • Nitrous oxide emissions in maize on mollisols in the Pampas of Argentina 

      Picone, Liliana; Bayer, Cimélio; Videla, Cecilia; Rizzalli, Roberto Héctor; Casanave Ponti, Sheila Mailén; Andrade, Fernando Hector; Garcia, Fernando (Elsevier, 2021-01-14)
      The objectives of this study were i) to measure the soil N2O fluxes in a cropping system currently adopted by farmers of the region (FP), and in an ecologically intensified cropping system (EI) over two consecutive maize ...

    • 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 ...

    • Soil carbon dioxide and nitrous oxide emissions during the growing season from temperate maize‐soybean intercrops 

      Dyer, Lisa; Oelbermann, Maren; Echarte, Laura (Wiley, 2012-06)
      The Argentine Pampa is one of the major global regions for the production of maize (Zea mays L.) and soybean (Glycine max L. [Merr.]), but intense management practices have led to soil degradation and amplified greenhouse‐gas ...
