Abstract

[Extract] Dear Editors-in-Chief, We read with interest the paper by Su et al. (2025) describing a soil incubation study. The paper provides useful data on the effect of wollastonite addition on CO2 emission/capture and soil properties. However, one of the main conclusions appears to directly contradict the data, perpetuating the unsupported notion that a significant amount of CO2 is captured during weathering of crushed silicate rock mixed into acidic soil.
