Biogeochemical simulation models are important tools for describing and quantifying the
contribution of agricultural systems to C sequestration and GHG source/sink status. The …

Forest ecosystems with low soil nitrogen (N) availability are characterized by direct
competition for this growth‐limiting resource between several players, ie various …

Future climate change is predicted to influence soil moisture regime, a key factor regulating
soil nitrogen (N) cycling. To elucidate how soil moisture affects gross N transformation in a …

The dramatic increase in anthropogenic reactive nitrogen (Nr) from agricultural activities
negatively affects the environment. An additional challenge is to ensure food security while …

Nitrogen management in soils has been considered as key to the sustainable use of
terrestrial ecosystems and a protection of major ecosystem services. However, the …

Identifying tipping points in the relationship between aridity and gross nitrogen (N) cycling
rates could show critical vulnerabilities of terrestrial ecosystems to climate change. Yet, the …

Nitrogen (N) fertilization affects both ammonia (NH 3) and greenhouse gas (GHG) emissions
that have implications in air quality and global warming potential. Different cropping systems …

Legume-based cropping systems have the potential to internally regulate N cycling due to
the suppressive effect of soil N availability on biological nitrogen fixation. We used a …

This study focuses on the microbial N cycle in the acid soil of a beech forest that falls in the
upper range of the N saturation continuum. Our objectives were:(1) to quantify microbial N …

The accurate measurement of the soil organic carbon (SOC) stock in Australian grazing
lands is important due to the major role that SOC plays in soil productivity and the potential …
