Fine-root turnover rates of European forests revisited: an analysis of data from sequential coring and ingrowth cores
Original language description
Forest trees directly contribute to carbon cycling in forest soils through the turnover of their fine roots. In this study we aimed to calculate root turnover rates of common European forest tree species and to compare them with most frequently publishedvalues. We compiled available European data and applied various turnover rate calculation methods to the resulting database. We used Decision Matrix and Maximum-Minimum formula as suggested in the literature. Mean turnover rates obtained by the combination of sequential coring and Decision Matrix were 0.86 yr(-1) for Fagus sylvatica and 0.88 yr(-1) for Picea abies when maximum biomass data were used for the calculation, and 1.11 yr(-1) for both species when mean biomass data were used. Using mean biomass rather than maximum resulted in about 30 % higher values of root turnover. Using the Decision Matrix to calculate turnover rate doubled the rates when compared to the Maximum-Minimum formula. The Decision Matrix, however, makes use of
