Production and consumption processes in soils contribute to the global cycles of many trace
gases (CH4, CO, OCS, H2, N2O, and NO) that are relevant for atmospheric chemistry and …

Terrestrial ecosystems with their main elements soil and plants may act, in principle, as both
source and sink for atmospheric nitric oxide (NO). The net exchange between ecosystems …

Regulation of trace N-gas production via nitrification and denitrification occurs at two
levels:(a) control of the rates of these processes and (b) control of the relative proportions of …

This review examines the interactions between soil physical factors and the biological
processes responsible for the production and consumption in soils of greenhouse gases …

Research to identify sources of nitrous oxide (N 2 O) in soils has indicated that most, if not
all, of the N 2 O evolved from soils is produced by biological processes and that little, if any …

Emission Of NOx (principally NO) and N2O from soils is reviewed with particular emphasis
placed on the atmospheric and ecological implications of this source. The photochemistry of …

While much is known about control of production of NO and N2O by nitrifying and
denitrifying bacteria at the cellular level, application of this knowledge to field studies has not …

Forests have long been considered as efficient sinks for atmospheric pollutants. The
potential for large rates of deposition is provided by the turbulent structure of air above and …

Nitrogen (N) cycling was analyzed in the Kalahari region of southern Africa, where a strong
precipitation gradient (from 978 to 230 mm mean annual precipitation) is the main variable …

There are many factors that affect denitrification and these have been reviewed by Delwiche
and Bryan (1976), Payne (1981), and Knowles (1982). None of these authors have provided …
