Temperature sensitivity of decomposition of labile fraction of organic matter of soils with different vegetation coverage
In my PhD research I will deal with the differences in the decomposition of labile fractions (DOM, POM) of soils with different vegetation coverage and if there is differences in the CO2 emission. This will be done by calculating the SOM normalized cumulative CO2 efflux (to eliminate the effect of different organic matter content). Also, What is the reason of differences in CO2 emission. Maybe differences in the chemical structure of DOM and POM fractions of soils from different vegetation coverage.
Check and analyse the difference in temperature sensitivity of decomposition of the labile fractions calculating Q10 for the labile fractions of all soils identically..
And if we find any discrepancy among the Q10 of soil labile fractions, whether this can be caused by the differences in the chemical structure of the labile fractions?
The instruments I will use are:
- UV-Vis spectroscopy (SUVA)
- fluorescence (PARAFAC)
- FT-IR (relative absorbances of the characteristic peaks)
- 2D correlation FT-IR spectroscopy (revealing the changes in the IR spectra with time)
