Release of greenhouse gases from different soils under laboratory conditions

Abstract

In two laboratory experiments, the release of ammonia, nitrous oxide, carbon dioxide and methane from ten different soils was tested with and without the addition of fermentation residue. Without the addition of fermentation residue, there was only a release of CO₂. With application of fermentation residue all investigated gases were released. In the fertilized soils, high scatter was present in the N₂O, CO₂ and NH₃ release. The closest relationship between the studied soil parameters and the gas release existed between sand content and NH₃ release. After application of fermentation residue the highest release of CO₂ equivalents (sum of all four gases) was found in the loamy sand soils.
