Fig. 6. Methane fluxes from the Nashua manure experiment site. Methane fluxes were measured the day before injected swine manure application (A) and immediately following swine manure application both between injection slots (B) and directly over injection slots (C). The small circles indicate the hourly CH4 fluxes of four individual chambers in each plot, and the large circles are chamber means in each plot. The horizontal lines indicate CH4 flux detection sensitivities.
