The soil type most vulnerable to wind erosion is fine-textured soil, specifically silt loam and sandy loam.

Here's why:

* Fine particles: Silt and sand particles are much lighter than clay particles, making them easier to pick up and transport by wind.

* Lack of aggregation: Fine-textured soils often have poor aggregation, meaning the particles are loosely bound together. This makes them more susceptible to wind erosion.

* Dry conditions: Dry soils are more vulnerable to wind erosion because the lack of moisture reduces the soil's cohesiveness.

While other soil types can be affected by wind erosion, fine-textured soils are particularly susceptible due to their physical properties.
