Effect of ISPAD Anaerobic Digestion on Ammonia Volatilization from Soil Applied Swine Manure
Figure 2
Cumulative NH3 volatilized during 47 hours following the land application of untreated swine manure from the open tank (a) and anaerobically treated swine manure ISPAD (b). The NH3 volatilization was measured using the laboratory wind tunnels. The data points are the average of and the error bars represent ± one standard deviation.
