Soil organic matter chemistry changes upon secondary succession in Imperata Grasslands, Indonesia: A pyrolysis–GC/MS study

The chemical composition of soil organic matter (SOM) following secondary succession in Imperata grassland was investigated by Pyrolysis-Gas Chromatography/Mass Spectrometry (GC/MS). We studied 46 samples from different stages of succession using plots that last burned 3 and 9 years previously, secondary forest (≥ 15 years), primary forest and Acacia mangium plantation (9 years). During regeneration of Imperata grasslands the chemical...
