Methodology

After a couple of days of practicing and rotating around different jobs, we finally have a stable method!

Once the core has been taken out of the ground we start a rota in which we all sort out the different components of the core. The different jobs include sorting moss in species, sorting plants in species, leaf area of the plants (only with fresh leave), weighing the inorganic layer and dead leaf litter.

Finally we finish with root sorting in which 4 of us pick out roots from four 7g sub samples, for 15 minutes each and then rotate until we have all picked out roots from each sub sample.
This way it means there is no bias towards the speed and amount if roots picked out by a single person!

Overall all is going well and we have been getting through 2-3 cores a day!
