the addition
of 30 g biochar kg1 soil resulted in significantly lower macro-
aggregate yields at 25 C incubation temperature compared to 5 C
after four weeks with an opposite effect observed for the CO2
emission rates. Independent from the incubation temperature and
time, the concentrations of macro-aggregates and the macro-
aggregate associated C (in % of the bulk soil C) detected for the
biochar treatments were smaller than the respective values of all
other treatments including the control.
