Humus-rich refers to soil that has a significant amount of humus, which is decomposed plant organic matter. This type of soil is not just fertile but also has a distinct composition.
Composition of Humus-Rich Soil
Humus-rich soil is specifically characterized by the following components:
- Sand: Provides aeration and drainage.
- Clay: Helps retain moisture and nutrients.
- Humus: At least a tenth of its composition comes from humus, the decomposed organic matter.
| Component | Role |
|---|---|
| Sand | Aeration and Drainage |
| Clay | Moisture and Nutrient Retention |
| Humus | Organic Matter and Fertility |
Characteristics of Humus-Rich Soil
- Location: Commonly found in forests and undergrowth environments.
- Acidity: It tends to be acidic, similar to peat soil. This means it has a lower pH value.
- Fertility: Due to its high humus content, it is naturally very fertile, making it good for plant growth.
Examples of Humus-Rich Soil Environments
- Forest Floors: Where decaying leaves and plant matter accumulate.
- Woodlands: Areas with plenty of undergrowth contribute to the humus layer.
In short, humus-rich soil is a valuable resource for growing plants due to its composition and fertility. Its high humus content, combined with sand and clay, creates a balanced environment that promotes healthy plant growth.
