Which factor does NOT influence soil erodibility?

Soil erodibility refers to the susceptibility of soil to erosion, which can be influenced by various factors such as soil texture, topography, and the percentage of organic matter. Each of these factors plays a significant role in how easily soil can be dislodged and transported by wind or water.

Soil texture is critical because it determines the size and composition of soil particles, affecting the soil's ability to retain moisture and its overall stability. For example, sandy soils are generally more prone to erosion compared to clay soils due to their larger particles and lower cohesion.

Topography, which refers to the terrain and landscape features of an area, also affects erosion. Steeper slopes generally result in higher rates of runoff and greater potential for soil erosion, whereas flat land tends to have lower erosion rates because water moves more slowly.

The percentage of organic matter in the soil is another important factor as it enhances soil structure, increases moisture retention, and improves soil cohesion. Higher organic content can lead to better aggregation of soil particles, making them less prone to be washed or blown away.

In contrast, plant species diversity may support soil health and ecosystem resilience but does not directly influence the soil's inherent properties regarding erodibility. While diverse plant species can contribute to soil
