Carbon dioxide in the soil is higher than in the atmosphere because of ongoing respiration in the ground. This is because microorganisms in the soil respire organic matter, releasing carbon dioxide as a byproduct. This process is ongoing and contributes to the higher concentration of carbon dioxide in the soil compared to the atmosphere.
