Effect of land use change (LUC) on SOM composition in Brazilian soils
Py-GC/MS of NaOH extractable SOM under native vegetation, pasture and sugarcane
Regional differences were mainly evident at 1 m depth and related to BC
LUC mainly affected SOM composition in surface soils (0-0.1 m)
Conversion to sugarcane increased compounds associated to fresh litter on SOM
