How Does Soil Trap Carbon?

Researchers have made use of experiments and computational modeling to study interactions between carbon molecules and clay minerals in the soil. They found that electrostatic charges, structural features of carbon molecules, surrounding metal nutrients in soil and competition among molecules all play major roles in the soil’s ability or inability to trap carbon.
