AI Technical Summary
Global warming and climate change exacerbate soil respiration, leading to increased CO2 emissions from soil, which is a significant carbon reservoir. Current methods for carbon sequestration in soils are inadequate to meet the scale and duration required to mitigate climate change.
A method involving the administration of a formulation comprising microorganisms, such as Bacillus subtilis, to silicate minerals in soil. The microorganisms enhance silicate weathering, converting CO2 into bicarbonate and locking it away in carbonate minerals, thereby sequestering carbon.
This approach significantly increases carbon sequestration rates, potentially reaching gigatonne scale CO2 removal annually, and enhances soil fertility by increasing base cations like calcium and magnesium.
