Towards Soil-based solution for Climate change  - Scientific European
A new study examined interactions between biomolecules and clay minerals in the soil and shed light on factors that influence trapping of plant-based carbon in the soil. It was found that charge on biomolecules and clay minerals, structure of biomolecules, natural metal constituents in the soil and pairing between biomolecules play key roles in sequestration of carbon in the soil. While presence of positively charged metal ions in the soils favoured carbon trapping, the electrostatic pairing between biomolecules inhibited adsorption of biomolecules to the clay minerals. The findings could be helpful in predicting soil chemistries most effective in trapping carbon in soil which in turn, could pave way for soil-based solutions for reducing carbon in atmosphere and for global warming and climate change.
