Soil carbon refers to the organic matter present in the soil, including microbes such as bacteria and fungi, as well as decomposed plant and animal material. Nearly all soil carbon originates from living or recently living organisms, or from materials derived from them. Soil carbon plays a crucial role in soil health, influencing structure, water retention, and drainage. Effective soil carbon management focuses on promoting biological activity within the soil and implementing practices that minimize carbon loss as organic matter breaks down.
