Verra has published an innovative digital soil mapping (DSM) tool that facilitates the robust and verifiable quantification of greenhouse gas emission reductions and carbon dioxide removals in agricultural land management (ALM) carbon projects. VT0014 Estimating organic carbon stocks using digital soil mapping, version 1.0 provides guidance for the development, calibration, and validation of data-driven modeling methods to estimate soil organic carbon (SOC) stocks in a spatially explicit manner, including model uncertainty estimations. Because the tool is based on robust, up-to-date science and novel technologies, such as remote sensing, it enables ALM projects to generate high-integrity carbon credits.
Compared with traditional soil sampling methods, digital soil mapping allows for broader spatial coverage, improved spatial resolution and precision, and increased cost-effectiveness.
