concentration was greater in C2 than in C0 under DT, and greater in
C2 and C1 than in C0 under ST. The SOC concentration was greater
under ST than under DT in both C1 and C2. The MWD was
C2 > C1 and C0 under DT and C2 > C1 > C0 under ST. The MWD was
weakly correlated with SOC concentration (R= 0.65,P= 0.077)
