Which texture of soil is described as having the lowest productivity and being very susceptible to wind erosion?

Coarse textured soils are characterized by larger particle sizes, such as sand and gravel. Due to their structure, these soils have a lower ability to retain moisture and nutrients compared to finer textured soils, leading to reduced fertility and lower overall productivity. In agricultural contexts, this means that crops grown in coarse soils often struggle to thrive due to insufficient water and nutrient availability.

Furthermore, the larger particles in coarse textured soils allow for increased air movement and make it easier for wind to disturb the soil. This makes them particularly susceptible to wind erosion, especially in arid or semi-arid regions where vegetation cover may be sparse. Soil erosion can lead to further degradation of soil quality, compounding the challenges already faced by these soil types in terms of productivity.

In contrast, moderate coarse, medium, and fine textured soils generally have better moisture retention and nutrient-holding capacities, providing more favorable conditions for plant growth and making them less prone to wind erosion.
