Abstract
Pyrolysis products derived from lignins, proteins and polysaccharides were identified in all samples. SOM under grassland, arable land and converted grassland released similar pyrolysis products. Three months after the conversion, lignin-derived pyrolysis products were found at lower concentrations in the converted grassland soil. Principal component analysis showed that arable land, grassland and the converted grassland could be distinguished using the score plot of the 2nd and 3rd principal components. The differences induced by grassland conversion are only transitory and 1 year after the conversion, SOM has a similar composition as SOM of the initial grassland soil.
