Figure 7: Cumulative NH4-N (mg NH4-N per manure storage unit) leached from manure of the rainy season storage experiment. Error bars represent standard error of the mean values. The continuous line represents best-fit regression equations for cumulative NH4-N (mg) leached from manure during the dry season experiment. represents the number of days in storage. The solid line represents all treatments. represents the cumulative NH4-N (mg) leached from the manure. All treatments: , .
