What contributes to soil erosion?

Excessive rainfall significantly contributes to soil erosion as it can lead to the oversaturation of soil. When rain falls heavily and rapidly, it can displace soil particles, especially if the ground is already wet. This displaced soil can then be transported by water runoff to other areas. Additionally, heavy rain can create puddles and streams on the land surface, further enhancing the movement of soil and leading to rill and gully erosion.

In contrast, healthy plant roots act as a stabilizing force in the soil, helping to hold it in place and reduce erosion. Soil amendments are often used to improve soil structure and fertility, which can also mitigate the effects of erosion when applied correctly. Regular plowing, while it can disturb soil structure, is a land management practice that can be conducted in a way that minimizes erosion, especially if measures such as contour plowing or cover cropping are implemented. Overall, excessive rainfall stands out as a significant natural factor leading to soil erosion.
