Abstract
Spruce has a higher aboveground production than pine and birch in southern Sweden and this was reflected in larger fine root biomass as well as higher fine root biomass production. The annual tree fine root biomass production (humus and 0-30 cm in mineral soil) was 73, 78 and 284 g m(-2) in pine, birch and spruce stands, respectively. Thicker fine roots tended to live longer. The majority of the fine roots were thinner than 0.5 mm in diameter, with a turnover rate (KM) of 0.4 year(-1). When comparing all fine roots, i.e. all roots 0-2 mm, pine had the highest longevity, 1120 days, compared with 900 days for spruce and 922 days for birch (KM). (C) 2013 Elsevier B.V.
