Estimating fine root longevity in a temperate Norway spruce forest using three independent methods
Functional Plant Biology
The importance of root systems for C cycling depends crucially on fine root longevity. We investigated mean values for fine root longevity with root diameter, root C/N ratio and soil depth using radiocarbon (14C) analyses in a temperate Norway spruce [Picea abies (L.) Karst.] forest. In addition, we applied sequential soil coring and minirhizotron observations to estimate fine root longevity in the organic layer of the same stand. The mean radiocarbon age of C in fine roots increased with depthdoi:10.1071/fp08195 pmid:32688623 fatcat:b7p6tyzm2rf5tgjdiwtfepk33q
