Nitrogen deposition and the release of carbon dioxide from different soils 2005 (English)Independent thesis Advanced level (degree of Master (One Year))Student thesis

Abstract [en]

In order to test if it was possible to induce nitrogen saturation and increased CO2 release in different soils a series of experiments was carried out. Soil samples were incubated for two days with different additions of N and then analysed for CO2 and N2O. The aim of these experiments was to find the point where the internal soil CO2 sink is broken down and the emission of CO2 increases. This situation was found in soil samples from Hainich, the other samples showed either decreased CO2 release (an internal CO2 sink is favoured) or no changes in CO2 release even with high N-supply. A transect from the forest edge receiving high N-deposition, to the closed forest in Gällared in South Sweden was included, but no significant differences in either CO2 release or soil inorganic nitrogen were found. This was probably due to the fact that winter conditions were still prevailing. The inorganic nitrogen in soils after the incubations was found to be significant smaller than before the incubations.
