Methane (CH4) and nitrous oxide (N2O) daily emission from grazing cattle dung patches
It was evaluated the impact of supplementing grazing steers with corn grain, which may affect the quality of faeces and thus the greenhouse gas emissions from dung pats. Data shows daily fluxes of methane (CH4) and nitrous oxide (N2O) from dung pats of supplementing grazing beef steers with corn grain, as well as the corresponding dung cumulative emissions and emission factors (EF). Also, contain meteorological data of the measured period. Dung was applied (1kg) on the soil surface inside cylindrical PVC collars. The site was located in Tandil (37°19'07"S, 59°04'42"W) Argentina. Gasses from dung (supplemented or not) patches and soil (control, i.e. without dung) were monitored over 125 days using the static chamber technique during 17 sampling occasions (Priano et al., 2014). Each dung treatment had five replicates whereas control chambers were only two. Total cumulative gas emissions were estimated by integrating the linear interpolation of the daily ﬂuxes over the monitoring period (OriginLab 2018 Software). In turn, emission factors (EF) were calculated as described by IPCC (2019).
