Soil organic carbon (SOC) depletion, primarily driven by land use change, is a global challenge influenced factors such as climate, plant cultivation, and adopted management practices. Poplar plantations (PP), predominantly used for plywood bioenergy production in the Mediterranean, have shown (C) potential capture biomass. However, their contribution to SOC climate change mitigation remains understudied. Thus, this study evaluates of PP enhancing stocks arable soils Northern Italy covering fifteen sites within six farms. under were analyzed, at 0-10 10-30 cm soil depths, using time-for-space substitution method (paired comparison), comparing cropland (CR) PP, spatial survey approach evaluating after thirty years PP. Additionally, conventional was also compared with c (PC), which integrate diverse tree species supporting biodiversity fostering sustainability. Results showed that maintains higher stock than CR management, significant variations observed fifty percent cases. Relative sequestration rates 0.09 0.32 Mg C ha-1 year-1 0‒10 10‒30 depth, respectively. The mean rate 0.75 ha‒1 year‒1 differential methods, initial loss early stages (1‒5 years). PC demonstrated greater rates, indicating its through European policies. Overall, shows has varies sites. Further investigation into fertilization deep-soil tillage needed understand impact on stocks. Moreover, direct engagement farmers revealed supply chain issues, highlighting need sustainability improvement.
