Critical biomass harvesting indicator for whole-tree extraction does not reflect the sensitivity of Swedish forest soils

There is a growing societal demand to increase the use of forest biomass for substitution of fossil fuels. The production of this biomass must be sustainable and an indicator for critical biomass harvesting (CBH) has been suggested in order to sustain forest soil fertility and mitigate soil acidific...
