Characteristics of Humus
The major characteristics of humus are:
- Color: Humus gives soil its dark color (black or brown) due to the presence of high organic matter content.
- Odor: Unlike fresh organic matter, humus is typically odorless or has a mild earth or soil smell.
- Texture: Humus is crumbly or spongy texture, which improves soil structure and facilitates root growth.
- Moisture Retention: Humus has sponge-like structure which helps to retain moisture in the soil, reducing water runoff and promoting drought resistance.
- Indicator of Healthy Soil: The presence of humus is often indicative of well-aerated, fertile soil with good biological activity.
What Is Humus?
Humus is a critical factor of soil, playing a role in its fertility. Humus forms as a result of the decomposition of plant, animal and other organic matter. It is rich in nutrients and serves as a vital reservoir of organic carbon in soil ecosystems. In this article, we will cover Humus in detail.
