What is Soil Texture?
The texture of the soil is dependent on
2- The shape of the particles
3- Gradation of the particles
When the textural classification of soil is concerned, we only take into consideration the particle size distribution. The other two parameters are difficult to incorporate into this classification.
Textural Classification System
The US Bureau of Public Roads recommends triangular classification system for soil which is commonly called as the textural classification system, where the three sides of the equilateral triangle represent the percentage of sand, silt and clay. Where the size of
- Sand = 0.05 – 2mm
- Silt = 0.005 – 0.05mm
- Clay = size < 0.005mm
