Soil Sampling Methodology

Measuring soil organic carbon is central to quantifying the climate benefits of regenerative grazing. This soil sampling methodology is a practical guide for measuring soil organic carbon as required by Duke Carbon Offset Initiative’s Regenerative Grazing Protocol. Striking a balance between accessible and rigorous, this methodology is designed to reduce time and cost burdens associated with traditional approaches. 

The document below provides basic information about designing a soil sampling plan, taking and analyzing samples, and quantifying soil organic carbon. It also includes several resources for learning more about soil sampling. ​
