High ammonia (NH 3) emissions from fertilized soil in China have led to various concerns
regarding environmental safety and public health. In response to China's blue skies …

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 …

Biochar can inhibit soil acidification by decreasing the H+ input from nitrification and
improving soil pH buffering capacity (pHBC). However, biochar is a complex material and …

Although crop residue return increases upland soil emissions of nitrous oxide (N 2 O), a
potent greenhouse gas, the mechanisms responsible for the increase remain unclear. Here …

Conservation tillage practices are widely proposed as an effective management approach to
guarantee soil productivity and sustainability by manipulating nutrient status, especially …

Nitrogen loss from cultivated soils threatens the economic and environmental sustainability
of agriculture. Nitrate (NO3−) derived from nitrification of nitrogen fertilizer and ammonified …

In Mediterranean regions, the accumulation of nitrogenous substrates in soil during summer
fallow period has been linked to pulses of N 2 O emissions upon soil rewetting. Although the …

Abstract Nitrogen (N) immobilization (Nim, including microbial N assimilation) and plant N
uptake (PNU) are the two most important pathways of N retention in soils. The ratio of Nim to …

Abstract Ammonia (NH 3) volatilization, a critical pathway of nitrogen (N) loss in
agroecosystems, is closely regulated by ammonium (NH 4+-N) availability and associated …

Liming is widely used to ameliorate acidic soils. However, few studies have addressed the
effects of different lime application rates on soil microbial communities. Specifically, the …
