The overall aim of this project is to scrutinize the effect of edge proximity on N cycling and N sequestration in temperate forest ecosystems. The specific aims are to investigate (i) whether and to what extent gaseous N emissions and the N pools and sequestration in the forest floor and mineral soil are affected by edge proximity, (ii) which forest floor and soil processes and factors are principally involved in the probably altered N cycling in the forest floor and the mineral soil, and (iii) how altered N cycling and N sequestration at edges relates to C sequestration
