Today we spent the first part of the day in camp analyzing soil and doing dendrochronology. We dug up a cubic square meters of soil in order to determine the below-ground biomass of one of our plots. We were particularly interested in the amount of roots present. We took the soil back to camp and used a sieve to separate the soil from the roots. We then weighed the below-ground biomass present. We will repeat this method for several of our plots. We also cut a tree trunk into disc in order to determine the age of the tree by sanding and counting tree rings. We determined the tree to be roughly 44 years old.
