For 5 C, 15 C and 25 C incubation temperatures, the macro-
aggregate dry mass concentration ranged from 233 to 606 g kg1
soil, from 91 to 637 g kg1 soil, and from 100 to 383 g kg1 soil
(Fig. 2), respectively, with the highest value from the slurry or
biochar + slurry treatment and the lowest from the biochar
treatment. The macro-aggregate associated C concentrations had
a similar distribution among the treatments as the macro-
aggregate dry mass concentrations. The macro-aggregates separated
from the biochar treatments accounted for 5–22% of bulk soil
C (Table 1). Those separated from the control and from the slurry or
manure treatments accounted for 14–34% and for 25–66% of bulk
soil C, respectively.
