M. Francesca Cotrufo, professor Department of Soil and Crop Sciences, Colorado State University, presents “A Coherent Measurement-Modeling Approach to Assess Soil Organic Matter Accrual in Agricultural Land.” Soil organic matter (SOM) provides many ecosystem services. I will present our latest framework to conceptualize SOM structure, formation, and persistence, and a coherent measurement-modeling approach we implemented and use. I will provide examples of applications of our approach to quantify and forecast SOM changes under regenerative agriculture.
