FTIR spectroscopy can predict organic matter quality in regenerating cutover peatlands.

Abstract : Vegetational changes during the restoration of cutover peatlands leave a legacy in terms of the organic matter quality of the newly formed peat. Current efforts to restore peatlands at a large scale therefore require low cost, and high throughout, techniques to monitor the evolution of organic matter. In this study, we assessed the Fourier Transform Infrared (FTIR) spectra of the organic matter in peat samples at various stages of peatland regeneration from five European countries. Using predictive partial least squares analyses, we were able to reconstruct both peat C:N ratio and carbohydrate signatures, but not the micromorphological composit ion of vegetation remains, from the FTIR datasets. Despite utilising different size fractions, both carbohydrate (< 200 μm fraction) and FTIR (bulk soil) analyses report on the composition of plant cell wall constituents in the peat and therefore essentially reveal the composition of the parent vegetational material. This suggests that FTIR analysis of peat may be used successfully for evaluation of the present and future organic matter composition of peat in monitoring of restoration efforts.
