Soils are subject to varying degrees of direct or indirect human disturbance, constituting a
major global change driver. Factoring out natural from direct and indirect human influence is …

Although it is well established that soils are the dominating source for atmospheric nitrous
oxide (N2O), we are still struggling to fully understand the complexity of the underlying …

Land-management options for greenhouse gas removal (GGR) include afforestation or
reforestation (AR), wetland restoration, soil carbon sequestration (SCS), biochar, terrestrial …

Gaseous ammonia (NH 3) is the most abundant alkaline gas in the atmosphere. In addition,
it is a major component of total reactive nitrogen. The largest source of NH 3 emissions is …

This study provides evidence of substantial increases in atmospheric ammonia (NH3)
concentrations (14 year) over several of the worlds major agricultural regions, using recently …

Atmospheric concentrations of the powerful greenhouse gas nitrous oxide (N 2 O) have

On 13 October 1908, Fritz Haber filed his patent on the “synthesis of ammonia from its
elements” for which he was later awarded the 1918 Nobel Prize in Chemistry. A hundred …

Humans continue to transform the global nitrogen cycle at a record pace, reflecting an
increased combustion of fossil fuels, growing demand for nitrogen in agriculture and …

Soils play a pivotal role in major global biogeochemical cycles (carbon, nutrient, and water),
while hosting the largest diversity of organisms on land. Because of this, soils deliver …
