Soil holds the largest portion of active carbon on earth, at an estimated equivalent of around three times the total amount of carbon stored in the atmosphere. Not only is carbon critical to soil function and productivity, but it is also a main component of overall healthy soil conditions that affects both animal and crop life. In this activity, simulate the production of carbon dioxide due to microorganisms in soil.
