Soil surface layers that are distinct from the rest of the bulk soil
Soil crusts are soil surface layers that are distinct from the rest of the bulk soil, often hardened with a platy surface. Depending on the manner of formation, soil crusts can be biological or physical. Biological soil crusts are formed by communities of microorganisms that live on the soil surface whereas physical crusts are formed by physical impact such as that of raindrops.
Biological soilcrusts are communities of living organisms on the soil surface in arid and semi-arid ecosystems. They are found throughout the world with...
