What is humus primarily derived from?

Humus is primarily derived from dead plants and animals as they decompose. The breakdown of organic matter from these sources results in a dark, nutrient-rich component of soil that is crucial for soil fertility and health. As organic materials such as leaves, roots, and animal remains undergo decomposition, they are transformed into humus through the action of microorganisms, fungi, and various biological processes. This accumulation of decomposed organic matter enriches the soil with essential nutrients, improves soil structure, enhances water retention, and supports the growth of plants. Recognizing this process is fundamental to understanding soil health and the role of organic matter in ecosystems.
