Transcribed Image Text:The image is a soil texture triangle, a diagram commonly used in soil science to classify soil types based on their texture. The triangle is a graphic representation of the proportions of sand, silt, and clay in soil.
### Explanation of the Diagram:
- **Axes**:
- **Bottom Axis (Blue)**: Represents the percentage of sand in the soil, ranging from 0% to 100% from right to left.
- **Left Axis (Red)**: Represents the percentage of clay, ranging from 0% to 100% from bottom to top.
- **Right Axis (Green)**: Represents the percentage of silt, ranging from 0% to 100% from top to bottom.
### Soil Texture Categories:
1. **Clay**: Located at the top of the triangle, indicating high clay content.
2. **Silty Clay**: Found to the upper right, indicating primarily clay with significant silt.
3. **Sandy Clay**: Located to the upper left, where clay is mixed significantly with sand.
4. **Clay Loam**: Centrally located, a balance of clay with loam characteristics.
5. **Silty Clay Loam**: Slightly to the right of center, indicating more clay and silt.
6. **Sandy Clay Loam**: To the left of center, indicating more clay and sand.
7. **Loam**: In the center, representing a balanced mix of sand, silt, and clay.
8. **Silty Loam**: Below and to the right of center, higher in silt.
9. **Sandy Loam**: Below and to the left, higher in sand.
10. **Loamy Sand**: Lower left, predominantly sand with slight loam characteristics.
11. **Silt**: Lower right, predominantly silt.
12. **Sand**: Bottom left, predominantly sand.
The texture of the soil influences its properties, such as water retention, permeability, and fertility, making this diagram a vital tool for agronomists, ecologists, and environmental scientists.
