* High Sand Content:
* Lack of Cohesion: Sand particles are large and don't bind together well, making the soil loose and easily dislodged by wind or water.
* Poor Water Infiltration: Sand doesn't hold water well, allowing rainwater to run off quickly and carry away soil particles.
* High Clay Content:
* Expansion and Contraction: Clay particles swell when wet and shrink when dry, creating cracks and fissures that make the soil vulnerable to erosion.
* Poor Drainage: Clay soils are dense and compact, hindering water infiltration and leading to runoff.
In contrast, soils with a balanced mixture of sand, silt, and clay (loam) are generally more resistant to erosion. This is because the different particle sizes create a more cohesive structure, improving water infiltration and reducing runoff.
