Guiding methodologies for soil sampling, processing and analyses to support rigorous soil carbon accounting

Scaling soil C solutions as a climate mitigation strategy relies on our ability to accurately quantify how land management affects soil organic C (SOC) stock changes, but quantification approaches vary.

Drs. M. Francesca Cotrufo, Megan Machmuller, and Jane Zelikova and research associate Rebecca Even are assessing how different soil field sampling and laboratory processing procedures affect the precision, accuracy, and cost of soil C stock measurements.
