    • 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 ...

    • Biological nitrification inhibition by Brachiaria grasses mitigates soil nitrous oxide emissions from bovine urine patches 

      Byrnes, Ryan C.; Nùñez, Jonathan; Arenas, Laura; Rao, Idupulapati; Trujillo, Catalina; Alvarez, Carolina; Arango, Jacobo; Rasche, Frank; Chirinda, Ngonidzashe (Elsevier, 2017)
      High nitrogen (N) concentration in bovine urine, which generally exceeds plant N uptake rates, results in the formation of hotspots of N loss when bovine urine is deposited on grazed pasture soils. High spatial variability ...
