Organic carbon (OC) is the primary energy source for microorganisms in soil. OC triggers nutrient availability for plant growth and plays a critical role in ecosystems. The total organic carbon (TOC) in soil affects color, nutrient capacity (cation and anion exchange capacity-CEC), nutrient stability and turnover, water relationships, aeration, cultivation, plant growth, and health. In the winter seasons, snow cover insulates and protects soil from deep frost. Deep frost can injure plant roots, alter the activity of the soil decomposer community, and cause problems with the TOC composition of the soil. Some abiotic factors, including global climate change and snow management processes by humans, can alter the snowpack and influence the dissolution and mineralization of TOC.
