- •
This paper examines the effects of land abandonment on soil organic carbon.
- •
SOC dynamics have been studied in the bulk soil and in the fractions.
- •
Only afforestation with Pinus nigra accelerates the recovery of SOC in the topsoil.
- •
Aggregation is an important mechanism promoting SOC stocks after afforestation.
- •
Pastureland should be considered in land management due to the importance in SOC stocks.
