    • 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 ...

    • 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 ...

    • 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 ...
