Which type of soil is generally resistant to erosion?

Clay soil is generally considered resistant to erosion due to its fine particles and strong cohesion. The small particle size of clay allows the soil to pack tightly together, which increases its stability and reduces the potential for being washed away by water or blown away by wind. Additionally, the plasticity of clay enables it to hold moisture, which can further contribute to its ability to resist erosion.

In contrast, sandy soil consists of larger, more granular particles that do not cling together as well, making it more susceptible to being washed or blown away. Silty soil, although having finer particles than sand, can remain vulnerable to erosion, especially when wet, as it can become easily displaced. Organic soil, which contains a high amount of decomposed plant material, can be rich in nutrients but may similarly lack the structural integrity needed to effectively combat erosion. Therefore, clay soil stands out as the most resistant to erosion among the types listed.
