Soil carbon sequestration efforts to date have been significantly hampered by the complexity and cost of measuring SOC authoritatively and affordably. Yard Stick's mission is to fix that problem. By reducing the cost of statistically-significant and agronomically-legitimate SOC measurement by 90%+, we can dramatically expand the opportunities for evidence-based regenerative practices to simultaneously improve ecosystem health, increase farmer/rancher livelihoods, and combat climate change. Yard Stick is an instant in-situ soil organic carbon and bulk density measurement technology designed primarily for field evaluation of soil carbon stocks and changes. Our offering combines technologies that are already published and well-validated by the founding scientific team, including NIR soil spectroscopy, stratified sampling protocol design algorithms, resistance-based in situ bulk density measurement, and an integrating data platform which establishes chain of custody for SOC data - a key requirement as regenerative agriculture and soil carbon efforts mature.
