Soil buffering capacity definition
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. http://nmsp.cals.cornell.edu/publications/factsheets/factsheet29.pdf
