Ectomycorrhizal (EM) fungi are very common in forest soils, but their role as a food resource for fungivorous soil animals is poorly known. We used two tree-girdling experiments in Picea abies forests and one experiment in a Pinus sylvestris forest,

Liming can counteract acidification in forest soils, but the effects on soil C and N pools and fluxes over long periods are less well understood. Replicated plots in an acidic and N-rich 40-year-old Norway spruce (Picea abies) forest in SW Sweden (Ha

Different forage grass models are used to simulate forage yield and nutritive attributes, but these models are seldom compared, particularly those for timothy (Phleum pratense L.), a widely grown forage grass species in agricultural regions with a co

The use of forest-derived biomass has steadily increased in Finland and Sweden during the past decades leading to more intensive forest management practices in the region, such as whole-tree harvesting, both above- and belowground. Stump harvesting r

Clear-cutting and subsequent site preparation is a common forest management practice in the Nordic countries. Slash and stumps have been suggested to replace fossil fuels in district heating plants. Stump/root removal from clear-cuts will reduce the

Climate change, unpredictable dry spells and human population growth are expected to increase the frequency of forest fires. Forest fires induce damage on soil ecosystems and seriously compromise their functionality and provision of ecosystem service

Stump harvesting is defined as an intensification of forest management in comparison with stem‐only harvesting and removal of tops and branches. It increases soil mixing and the proportion of bare soil. In contrast to earlier hypotheses, stump harv

Clear-cutting often results in a dramatic change in the soil nitrogen (N) balance. This study analysed the fate of inorganic soil N over four years (1992–1995) in a new clear-cut containing three replicate blocks. Treatments comprised control (0),
