This Protocol provides the requirements and procedures for the calculation of net carbon dioxide equivalent (CO₂e) removal from the atmosphere via enhanced weathering (EW) in agricultural settings. Agricultural EW is considered a subcategory of EW approaches. Silicate weathering naturally sequesters approximately 0.1-0.3 Gt of CO₂ per year1 ,2 ,3 and is thus a critical feedback mechanism in global climate regulation on geologic timescales. In this process, atmospheric CO₂ dissolved in surface water reacts with silicate rocks and is converted to dissolved inorganic carbon or carbonate minerals, both of which constitute stable sinks for CO₂ on geologic timescales4 ,5. Natural weathering can be accelerated by applying crushed silicate rock to agricultural land, where the increased reactive surface area of the rock and damp conditions in the soil lead to elevated reaction rates. Alkaline species produced through weathering reactions allow for the increased storage of CO₂ in the aqueous pha
