Overview

Randomized trial investigates carbon inputs in plantation forests, suggesting species and depth matter for soil health.

Key Points

  • The aim is to understand how tree species and stand density influence root exudate carbon inputs and soil organic carbon pools across different soil depths.
  • Investigated black locust and Chinese pine at five stand-density levels on the Loess Plateau.
  • Quantified root exudation rates and fluxes, along with soil organic carbon fractions.
  • Analyzed the relationships between root exudation and soil organic carbon across different depths.
  • Black locust showed higher root exudation rates in the topsoil (0–30 cm) compared to Chinese pine.
  • Root exudation fluxes for Chinese pine were greater across a 0–100 cm depth gradient than for black locust (6.48–12.24 vs. 4.76–10.58 g C·m−3·year−1).
  • Increasing stand density decreased root exudation rates and soil organic carbon primarily in the topsoil.
