Soils managed with synthetic pesticides and fertilizers hold 28.6% less organic carbon than organic

"In soils under organic management, the SOC [soil organic carbon] stocks averaged 37.4 tonnes C ha-1, in comparison to 26.7 tonnes C ha-1 under non-organic management."

Calculation: 37.4-26.7=10.7/37.4=.286, or 28.6% less SOC.
