Effect of slowly cycling P on ecosystem C and N accumulation

Feedback form is now closed.
In terrestrial systems the nitrogen (N) cycle is more open than the phosphorus (P) cycle. New N inputs can accumulate over decades to centuries, and be lost from the system when N is in excess of biological demand. In contrast, new plant available P often comes from slowly cycling soil pools already present within the system. In this way, long term rates of ecosystem C and N accumulation may be constrained by stocks of slowly cycling P at the landscape scale. Evidence for this is emerging from forested LTER sites in the Eastern United States. This workshop seeks participants to pull together landscape and regional datasets of ecosystem N and C stocks (soil and vegetation) across the LTER network, to assess their relationship to stocks of slowly cycling soil P. Prior to the ASM we will work with participants to summarize site-level correlations between these variables, and spend the session discussing results. The goal of this workshop is a synthesis paper and future working groups.
