soil sealing

Term source

Status of the World’s Soil Resources, FAO/ITPS, 2015 (http://www.fao.org/3/a-bc607e.pdf).

Definition

The permanent covering of the soil surface with impermeable artificial materials such as asphalt and concrete. It is generally related to urban development and infrastructure construction, which in most cases leads to the absolute loss of the soil resource and of most of its ecosystem services.

Remarks

The rapid drop in infiltration rate of most bare soils during rainstorms is due mainly to the formation of surface seal. [...] Surface sealing, as well as most other crust formations, results from three processes: physical disintegration of soil aggregates and their compaction, caused by the impact of raindrops; chemical dispersion of the clay particles. The low electrical conductivity of the rainwater as well as the organo-chemical bonds between the primary particles of the surface aggregates, dictate the rate and degree of dispersion; an interface suction force which arranges suspended clay particles into a continuous dense layer. Such almost impermeable layers form right on the surface of the soil or in the immediate subsurface washed-in layer.
