What does soil roughening achieve?

Soil roughening is a technique used to enhance the stability of soil and minimize erosion by altering the soil surface. By mechanically creating a rougher surface, soil roughening increases the surface area for water infiltration and can trap sediment and water, thereby reducing the velocity of water flow over the soil. This can help to stabilize the soil during and after rainfall events, assisting in erosion control.

While increasing soil drainage can be an indirect benefit of proper soil surface treatment, the primary objective of soil roughening is to modify the soil surface texture directly. It's focused specifically on the mechanical alteration of the surface details. The rough texture provides better conditions for water infiltration and can also foster the establishment of vegetation, but these aspects are secondary to the act of roughening itself.
