• Forests stock ~ 861 Gt C

• Carbon sink ~ 2.4 Gt C per

year

• Soil respiration ~ 70 Gt C

per year

Why do we care about forest soil?

Preliminary Results

• Soil respiration was higher after the fumigation started.

• Soil respiration higher in fumigated plots for all different collar treatments.

• 1st year fumigation was higher than 2nd year fumigation.
