Enhanced silicate rock weathering (ERW) on cropland soils can increase crop yield and promote carbon dioxide sequestration. Applying silicate rock powder to flooded rice paddies can promote weathering, but the effects of ERW on rice production and CO₂ removal rates in the field remain unclear. The authors investigated the effects of adding wollastonite (CaSiO₃) powder (5 t ha⁻¹) to rice paddy plots on soil properties, rice yield, rice grain quality, grain arsenic, grain cadmium, and soil CO₂ sequestration in Liaoning Province, Northeast China.
