Dissolved organic matter (DOM) in soils plays an important role in the biogeochemistry of
carbon, nitrogen, and phosphorus, in pedogenesis, and in the transport of pollutants in soils …

We reviewed the experimental evidence for long-term carbon (C) sequestration in soils as
consequence of specific forest management strategies. Utilization of terrestrial C sinks …

This report is the first complete assessment of the science of climate change since Working
Group I (WGI) of the IPCC produced its second report Climate Change 1995: The Science of …

Human production of food and energy is the dominant continental process that breaks the
triple bond in molecular nitrogen (N2) and creates reactive nitrogen (Nr) species. Circulation …

Nitrogen emissions to the at-mosphere due to human activity remain elevated in in-
dustrialized regions of the world and are accelerating in many develo** regions (Galloway …

The concentration of CO2 in the atmosphere has risen from close to 280 parts per million
(ppm) in 1800, at first slowly and then progressively faster to a value of 367 ppm in 1999 …

Global flows of reactive nitrogen (N) have increased significantly over the last century in
response to agricultural intensification and elevated levels of atmospheric deposition …

Dissolved organic carbon (DOC) concentrations in 22 UK upland waters have increased by
an average of 91% during the last 15 years. Increases have also occurred elsewhere in the …

The impact on nitrogen (N) and phosphorus (P) cycles of human activity is a growing
concern and has several causes and consequences (MacDonald et al., 2011; Peñuelas et …

Average nitrogen (N) deposition across Europe has declined since the 1990s. This resulted
in decreased N inputs to forest ecosystems especially in Central and Western Europe where …
