    • 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 ...

    • Dinámica de las emisiones de N2O, CH4 y CO2 en mallines de Patagonia Norte 

      Enriquez, Andrea Soledad; Vangeli, Sebastián; Posse Beaulieu, Gabriela (Asociación Argentina de la Ciencia del Suelo, 2020-10-13)

    • Fertilización nitrogenada y emisiones de oxido nitroso en cultivo de maíz 

      Alvarez, Carolina; Alvarez, Carina; Alves, Bruno J.R.; Costantini, Alejandro Oscar (Asociación Argentina Ciencias del Suelo, 2023-04-01)
      El óxido nitroso (N20) es un gas de efecto invernadero (GEI) y la agricultura es la principal fuente antropogénica de este gas. El estudio evaluó las emisiones de N2O a partir del uso de diferentes tipos (urea y UAN) y ...

    • 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 emission after the addition of organic residues on soil surface 

      Gregorutti, Viviana Carolina; Caviglia, Octavio (Elsevier, 2017)
      The addition of organic amendments with a low Carbon:Nitrogen (C:N) ratio to restore degraded soils may increase the emission of greenhouse gases and affect the storage of these elements in the topsoil. Our objectives were ...

    • Nitrous oxide emissions in corn (Zea mays L) as affected by timing, method of application and source of dairy manure.
