- Abstract:
- Estimates of the effect of N enrichment on current global C sequestration vary from 0.25-2.0 PgC/yr. The large range reflects uncertainty about the fate of deposited N, interactions with C dynamics and environmental responses. To lessen uncertainty we shall evaluate the performance of 5 contrasting forest-soil models which couple the C, N and water cycles. Evaluation includes reviews of the current state of knowledge of key N transfer processes and the application of formal model analysis techniques. Improved, validated models will be used to scale up to biome and global scales, giving improved estimates of C sequestration due to N deposition, with associated errors and identification of sources of uncertainty.
