(a) Geometric mean nitrous oxide emissions from different treatments following urine application (error bars ± one geometric standard error of the mean, *n* = 5); (b) Nontransformed cumulative loss of N_{2}O from urine-treated soils, showing the amount of N emitted as N_{2}O-N as a percent of the total N applied to the plots. Nil urine is also plotted to show control emissions. (Error bars ± one standard error of the mean, *n* = 5).
