Fig. 1. (a) Cumulative evolved CO2, and (b) apparent percentage of black liquor derived C evolved as influenced by black liquor application rates. I: LSD0.05 bars: significant differences among treatments at each sampling date at p 0.05; and NS: no significant differences among treatment at each sampling date.
