The draining and fertilization of peatlands for agriculture is globally an important source of the greenhouse gas nitrous oxide (N2O). Hitherto, the contribution of major sources to the N2O emission—that is, fertilization and nitrogen (N) release from peat decomposition—has not yet been decipher...
Forest ecosystems may provide strong sources of nitrous oxide (N2O), which is important for atmospheric chemical and radiative properties. Nonetheless, our understanding of controls on forest N2O emissions is insufficient to narrow current flux estimates, which still are associated with great ...
Yield-scaled emissionsDrip-fertigated systems are widely used for crop production in arid regions to improve water and nutrient use efficiency. However, the effect of fertilizer nitrogen (N) sources on nitrous oxide (N 2 O) emissions from such systems is not well understood. A field experiment...

Increasing salt–affected agricultural land due to low precipitation, high surface evaporation, irrigation with saline water, and poor cultural practices has triggered the interest to understand the influence of salt on nitrous oxide (N2O) and carbon dioxide (CO2) emissions from soil. Three soils wit...

As human impacts on the global nitrogen cycle grew rapidly from the industrial revolution onwards, human-induced nitrous oxide emissions also increased. Today, so-called ‘natural sources’ still account for 60 per cent of worldwide emissions each year, but the human-induced component is becoming ...
Intensive measurement of nitrous oxide emissions from a corn–soybean–wheat rotation under two contrasting management systems over 5 years No-tillage (NT), a practice that has been shown to increase carbon sequestration in soils, has resulted in contradictory effects on nitrous oxide (N 2 O) e...

Polluted rural creek systems are a potential primary source of nitrous oxide (N2O). However, to date, the N2O emission pathways of rural creek systems have yet to be investigated. In particular, the correlations between N2O emissions and ammonia-oxidizing archaea (AOA), ammoniating bacteria (AOB...
