The study looked at soil changes in areas affected by an earthquake. They compared soil in areas with destroyed vegetation to areas with undestroyed vegetation. They found that soil in the damaged areas had smaller particles and higher fractal dimensions. Clay content was higher in damaged areas, while organic matter and nitrogen were lower. Soil recovery was better at lower slopes. The study showed that soil fractal dimension is related to particle size and clay content. Overall, restoring vegetation in damaged areas helps improve soil quality over time.
