Nitrification, a microbial process, is a key component and integral part of the nitrogen (N)
cycle. Soil N is in a constant state of flux, moving and changing chemical forms. During …

The supply of nitrogen commonly limits plant production in boreal forests and also affects
species composition and ecosystem functions other than plant growth. These interrelations …

Forestry reshapes ecosystems with respect to tree age structure, soil properties and
vegetation composition. These changes are likely to be paralleled by shifts in microbial …

We compiled regional and continental data on inorganic nitrogen (N) in seepage and
surface water from temperate forests. Currently, N concentrations in forest waters are usually …

Temperate forests are increasingly subject to natural disturbance by stand replacing
windthrows or bark-beetle attacks. Forests are commonly salvage logged after disturbance …

Human activity has had the single largest influence on the global nitrogen (N) cycle by
introducing unprecedented amounts of reactive-N into ecosystems. A major portion of this …

A bstract The structure, biomass, and activity of the microbial community in the humus layer
of boreal coniferous forest stands of different fertility were studied. The Scots pine dominated …

This paper summarizes results from fertilization research carried out in Scots pine (Pinus
sylvestris L.) and Norway spruce [Picea abies (L.) Karst.] stands growing on mineral soil in …

Nitrogen (N) availability plays multiple roles in the boreal landscape, as a limiting nutrient to
forest growth, determinant of terrestrial biodiversity, and agent of eutrophication in aquatic …

Background Agriculture is the single largest geo-engineering initiative that humans have
initiated on planet Earth, largely through the introduction of unprecedented amounts of …
