WebJan 23, 2024 · Each soil has a buffering capacity, which is the ability of the soil to neutralize acids. An alkaline soil, for example, has a high buffering capacity, because it can absorb high amounts of acidic precipitation without a pH change. Alkaline soil is less harmed by acid rain than sensitive soils with low buffering capacities are.

"WebLiquid water may soak into the soil in a process called infiltration. The water will move into the spaces between the solid particles of the soil, and gravitational pull will cause the water to soak deeper into the soil until it is fully absorbed. If precipitation exceeds the infiltration capacity of the soil, surface runoff will occur. " - Soil buffering capacity definition
