The nitrogen (N)-use efficiency of agricultural plants is notoriously poor. Globally, about 50%
of the N fertilizer applied to crop** systems is not absorbed by plants, but lost to the …

Calcareous soils are widely spread in arid and semi-arid regions and cover almost one-third
of the world's land surface area. This chapter gives an overview of the distribution and …

Crop** systems have fertilized soils for decades with undetermined consequences for the
productivity and functioning of terrestrial ecosystems. One of the critical unknowns is the role …

Ammonia (NH 3) volatilization is a major pathway of nitrogen (N) loss in agricultural systems
worldwide, and is conducive to low fertilizer N use efficiency, environmental and health …

Agriculture affects climate change and contributes directly and indirectly to greenhouse gas
(GHG) emissions. However, no reports have fully quantified the GHG emissions from …

The existence of gas‐phase ammonia (NH3) in the atmosphere and its interaction with other
trace chemical species could have a substantial impact on tropospheric chemistry and …

Recent 15 nitrogen (N) tracing studies have shown that unlabeled N 2 O emissions (UNEs)
following 15 N fertilizer application tend to be higher than those from zero-N controls, which …

Rice (Oryza sativa L.) is a staple food for three billion people and paddy fields contribute
greatly to greenhouse gases (GHG) emission and environmental nitrogen losses. Rice …

In this study, a 15 N tracing incubation experiment and an in situ monitoring study were
combined to investigate the effects of different N fertilizer regimes on the mechanisms of soil …

It is urgently necessary to reduce environmental harm while simultaneously ensuring food
security from agriculture in China. Fertilizer deep placement, especially urea deep …
