The amount of inorganic-N remaining in soils after the three simulated heavy rain events. The amounts of (a) -N and (b) -N were shown in separate figures. The error bars indicate standard deviations (). The small letters on each bar indicate significant difference within each aggregate size. The capital letters indicate significant difference within each treatment to show the effect of aggregate size on each urine treatment.
