An integrated assessment of the potential of different management practices for mitigating
specific components of the total GHG budget (N 2 O and CH 4 emissions and C …

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 …

The internal soil nitrogen (N) cycle supplies N to plants and microorganisms but may induce
N pollution in the environment. Understanding the variability of gross N cycling rates …

Soil gross nitrification (GN) is a critical process in the global nitrogen (N) cycle that results in
the formation of nitrate through microbial oxidation of ammonium or organic N, and can both …

Using 15 N stable isotope as a tracer to quantify N transformation rates in isotope-
enrichment experiments improves understanding of the N cycle in various ecosystems …

Microbial nitrogen (N) immobilization, which typically results in soil N retention but based on
the balance of gross N immobilization over gross N production, affects the fate of the …

For the past 3.8 billion years, the geochemistry of the Earth's surface-its atmosphere, waters
and exposed crust-has been determined by the presence of biota. Photosynthetic organisms …

Until recently, the common view of the terrestrial nitrogen cycle had been driven by two core
assumptions—plants use only inorganic N and they compete poorly against soil microbes …

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 …

This chapter outlines the methodologies and the concepts used to assess soil internal
nitrogen (N)‐cycle processes. It discusses laboratory and field methods for determining …
