Ingrowth cores

Jhon: thanks for your question. We frequently encounter this issue in the Andes plots. Yes, you should consider the two layers separately (and also the A and B horizons on the mineral soil). When you install a root-free core, put in the appropriate soil in layers to match the natural horizons of the soil. When you count roots, it is interesting to count how many are in each horizon though this is not essential.
