According to the provided reference, sandy soil can be classified according to its loam content.
Loam, which consists of particles deposited by wind, ranges in size from 0-50 μm. The proportion of this loam content within the sand determines the specific classification of the sandy soil.
Sandy Soil Classification by Loam Content
The classification outlined in the reference is based on distinct ranges of loam percentage:
- Low-Loam Sand: Contains a very small amount of loam.
- Loamy Sandy Soil: Has a notable presence of loam, influencing its characteristics.
- Loamy Soil: Contains a significant proportion of loam, often considered a balanced soil type (though this specific definition goes beyond 'sandy soil' per the table ranges).
Here's a breakdown of the classifications based on their loam content, as specified:
| Classification Name | Loam Content (%) |
|---|---|
| Low-loam sand | 0 - 10 |
| Loamy sandy soil | 10 - 50 |
| Loamy soil | Over 50 |
This method provides a way to differentiate sandy soils based on the finer particles (loam) mixed within the sand grains, impacting properties like water retention and nutrient availability.
