Chemical changes to nonaggregated particulate soil organic matter following grassland-to-woodland transition in a subtropical savanna

Encroachment of thorn woodlands into grasslands of southern Texas has resulted in greater aboveground and belowground biomass and greater soil organic carbon (SOC) stocks. Our previous studies showed that a large percentage of the SOC accrued under invading woody clusters was not stabilized within p...
