Soil electrical conductivity can help track how much carbon dioxide is being removed from the atmosphere by a process called enhanced weathering. By using sensors to measure the electrical conductivity and water content of soil, researchers can see how adding certain substances to the soil affects its ability to absorb CO2. In some types of soil, the presence of organic material can make it harder to detect these changes. It's important to understand how the soil's ability to exchange cations and buffer pH levels can impact the effectiveness of enhanced weathering in capturing CO2. This information is crucial for accurately monitoring and verifying the success of carbon dioxide removal efforts in soils.
