Enhanced Rock Weathering (ERW) involves the application of crushed silicate-rich minerals to agricultural soils as a promising Carbon Dioxide Removal (CDR) strategy, with potential benefits for soil health and crop productivity. Effective Monitoring, Reporting, and Verification (MRV) techniques are essential for carbon credit validation and scalability of ERW. Current MRV methods, such as in-field soil porewater extraction, represent a potential barrier for scaling-up ERW because the accuracy, sensitivity, and consistency of this technique is limited by soil moisture availability. Here the authors test a new technique for quantifying ERW called the SATuration Centrifugation (SAT-C) technique, which could prove to be a more accurate, sensitive, and consistent means of quantifying ERW.
