    Measure-and-remeasure as an economically feasible approach to crediting soil organic carbon at scale by Eric Potash, Mark A Bradford, Emily E Oldfield, Kaiyu Guan

    Published 2025-01-01
    “…We analyze multi-field measure-and-remeasure SOC projects with two key features: first, practice assignment is randomized to compare the effect of a treatment (e.g. no tillage) to a control (e.g. conventional tillage); second, a random subset of fields is sampled (two stage cluster sampling) to cost-effectively measure SOC changes. We use statistical modeling to characterize the estimated treatment effect, accounting for within-field and between-field variability in SOC change, as well as measurement error. …”
