Silicon is not traditionally considered a limiting cofactor for plant growth, but researchers are finding that despite ample amounts of silicon in most soils, plants supplemented with silicon often …

Enhanced silicate rock weathering (ERW) on cropland soils can increase crop yield and promote carbon dioxide (CO2) 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.
