Change of 15N natural abundance (δ15N) in a forest soil receiving elevated N deposition
Description
Natural abundance of 15N (δ15N) has been used to interpret N mineralization in forest ecosystems. Forest litter typically has depleted δ15N values ranging from -8 to 0 per mille and δ15N values of organic N in forest soil profiles become more enriched with depth. This study investigated (1) the change of δ15N and total N with depth, and (2) the relation between the change of δ15N within the 0 to 10, 10 to 20 and 20 to 30 cm intervals of the mineral layer and the N mineralization rates in these layers
