Total OC mass in the surface 60 cm of the Durant soil, averaged across treatments, was 95.7 t ha−1 compared to 56.7 t ha−1 in the Teller soil. In the Durant soil, OC decreased as SR increased, with the non grazed exclosure having the greatest amount of soil OC. In contrast, the Teller soil had similar amounts of OC in the soil profile with all grazing treatments, but less without grazing. Total soil nitrogen followed similar trend as the soil OC. Soil properties should be considered to accurately assess the potential of grazing land to sequester carbon. ER -
