- Abstract:
- Large uncertainties, due to methodological limitations in both measurement and simulation, limit our ability to properly model SOM dynamics at low/freezing temperature in northern soils. The aim of this proposal is to investigate SOM decomposition under low to sub-zero temperatures, and to develop a general relationship for soil modelling under these conditions. Samples from northern/alpine soils will be incubated at a gradient of temperatures between 25~-10 degrees C, and in different moisture regimes. Respired CO2 from chambers will be measured using an IRGA/GC. The response of SOM decomposition to temperature will be used to develop a general pattern of soil processes at freezing temperatures and applied to northern soils. Weighted regression techniques will be used for model development. Uncertainties analysis and comparisons with other models will be conducted.
