- •
POX-C, MBC, and CWEOC were higher in undisturbed forests and pastures than in agriculture.
- •
Agricultural land uses had relatively higher proportion of non-labile C than original forest and pasture counterparts.
- •
Losses of up to 30% of the preexisting SOC stocks and 60% of total N stocks occurred in cropland soils.
- •
Carbon pool index was more sensitive than lability index to reflect the influence of land use changes on C dynamics.
- •
Labile organic carbon pools were more sensitive to land use changes than TOC contents of the soils.
