In this review we explore the biotic transformations of nitrogenous compounds that occur
during denitrification, and the factors that influence denitrifier populations and enzyme …

Methane emission by soils results from antagonistic but correlated microbial activities.
Methane is produced in the anaerobic zones of submerged soils by methanogens and is …

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 …

Soils are the main sources of the greenhouse gas nitrous oxide (N2O). The N2O emission at
the soil surface is the result of production and consumption processes. So far, research has …

Agriculture is the human enterprise that is most vulnerable to climate change. Tropical
agriculture, particularly subsistence agriculture is particularly vulnerable, as smallholder …

The oxidation of methane by methane-oxidising microorganisms is an important link in the
global methane budget. Oxic soils are a net sink while wetland soils are a net source of …

Soil compaction and soil moisture are important factors influencing denitrification and N2O
emission from fertilized soils. We analyzed the combined effects of these factors on the …

Bioenergy from crops is expected to make a considerable contribution to climate change
mitigation. However, bioenergy is not necessarily carbon neutral because emissions of CO …

It is anticipated that organic farming systems provide benefits concerning soil conservation
and climate protection. A literature search on measured soil-derived greenhouse gas …

Tillage practices and weather affect the release of greenhouse gases but there have been
few integrated studies of the quantities released or the mechanisms involved. No-tillage may …
