Technical Field

[0002] Soil organic carbon (SOC) is a collective term for humus, plant and animal debris, and microorganisms formed through microbial activity. Based on their availability to microorganisms, SOC is divided into readily degradable, recalcitrant, and inert organic carbon. Easily degradable organic carbon has higher bioavailability and loss rates, while recalcitrant organic carbon has higher residual rates. These carbons generally account for 60% to 80% of soil organic matter, with a significant portion participating in the formation of humus. The soil organic carbon incineration method is a common method for determining soil organic carbon content. Its basic principle is to dry and burn a soil sample at high temperature to oxidize the organic matter into carbon dioxide. The amount of carbon dioxide generated is then measured to indirectly calculate the soil organic carbon content.
