In the 72-plot factorial design, ERW-amended broadleaf plots stored 27% more aboveground tree carbon by 2024 than unamended plots, whereas ERW effects on spruce carbon sequestration were not statistically significant. Soil inoculum effects varied among species and diminished through time.",

  "searched": "Read the primary Communications Sustainability field-trial paper and an independent 2026 EGU ecosystem-flux abstract from the same site/network. Checked site, plot and tree denominators, four-year 2021–2024 window, species/forest-type scope, aboveground versus whole-ecosystem carbon accounting, treatment interactions, and time-course. The 27% result is broadleaf plot-level aboveground tree carbon relative to unamended plots; it does not establish a net ecosystem carbon-removal benefit, and inoculum effects were species- and time-dependent."
