The cover crop treatment for each tillage system in Table 2, column 7 did offset the SOC stock loses from CP
systems and resulted in gains for the NT, CP, and MP systems of +1.21 Mg∙C∙ha−1

, respectively. The NT system with cover crops and
without cover crops sequestered the most SOC when compared to the pre-treatment 2000 baseline SOC stock.
