• can be used as a geoengineering tool that has the potential to rapidly sequester significant amounts of atmospheric CO2 through enhanced inorganic carbon accumulation in agricultural soils;
• when used as a pH modifier in place of agricultural lime, avoids the creation of 26-44 wt% of CO2 released by the lime;
• provides plant available silicon which enhances crop resistance to biotic and abiotic stresses and improves crop yields.
