Decomposition, nitrogen mobilization, nitrogen fixation and the importance of lakeside foams in fellfield soils of the Garwood Valley
Entry ID: K052_1991_1992_NZ_1

[ Update this Record ]

Summary
Abstract: Nitrogen, a necessary nutrient for plants and microbes, is frequently limiting in soils. Nitrogen fixation and decomposition, both ways plants and microbes obtain nitrogen, are very slow processes in Antarctica and probably not ecologically important. However, little work has been reported on this subject in Antarctica, and therefore this study's aim was to determine the extent of and factors and ... View entire text
