To gain a better understanding of belowground drivers in order to develop the capacity to predict and model the coupling of carbon and nutrient cycling during forest growth, and their feedbacks to the atmosphere.
- Determine total BCA in four of the tree species where BCA is calculated as:
BCA = Rsoil – Litterfall + net root biomass increment + DSOM, where Rsoil (soil respiration) and root growth are measured in situ.
- Determine Arbuscular Mycorrhizal Fungi (AMF) biomass, colonization in fine roots, and community composition.
- Evaluate microbial processes, such as enzyme production and decay rates, and functional genes.
- Quantify soil carbon and nutrient dynamics.
- Quantify carbon and nutrient uptake by the vegetation.
