Role and function of humus
Humus is a complex organic substance resulting from the breakdown of plant material in a process called humification. This process can occur naturally in soil or the production of compost. Humus is extremely important to the fertility of soils in both a physical and chemical sense.
- Humus contains many useful nutrients s for healthy soil. One of the most important is nitrogen .
- Nitrogen is a key nutrient for most plants. Agriculture depends on nitrogen and other nutrients found in humus.
- When humus is in soil, the soil will crumble.
- Air and water move easily through the loose soil, and oxygen can reach the roots of plants.
