[ID: 189] Nitrogen deposition and soil respiration
Nitrogen deposition can enhance the boreal forest carbon sink but the amount of carbon stored in the soil per unit of nitrogen deposition is likely to depend on competition for nitrogen between different sinks in the soil. In this project we use the Åheden long-term nitrogen addition experiment and a root trenching treatment to study the impact of a gradient of simulated nitrogen deposition rates on the emissions of carbon from respiration in the tree root zone, as well as from free living heterotrophic organisms.
