The shrink–swell capacity of soils refers to the extent certain clay minerals will expand when wet and retract when dry. Soil with a high shrink–swell capacity is problematic and is known as shrink–swell soil, or expansive soil . [ 1 ]
Expansive clay is a clay soil that is prone to large volume changes (swelling and shrinking) that are directly related to changes in water content. [1] Soils with a high content of expansive minerals can form deep cracks in drier seasons or years; such soils are called vertisols.
Properties that are influenced by soil texture include porosity, permeability, infiltration, shrink-swell rate, water-holding capacity, and susceptibility to erosion. In the illustrated USDA textural classification triangle, the only soil in which neither sand, silt nor clay predominates is called loam.
After recording their first John Peel session Swell Maps went into WMRS studio to record their first album A Trip to Marineville, which was released in 1979. [6] They recorded a second album, Swell Maps in "Jane From Occupied Europe", in 1980. The band toured Belgium, the Netherlands and Italy before splitting up in April 1980.
The Legend for this map, published in 1974 under the leadership of Rudi Dudal, became the FAO soil classification. Many ideas from national soil classification systems were brought together in this worldwide-applicable system, among them the idea of diagnostic horizons as established in the '7th approximation to the USDA soil taxonomy' from 1960.
Jane from Occupied Europe (stylised as ...In "Jane from Occupied Europe") is the second and final album by English post-punk band Swell Maps. It was released in 1980 by Rather Records and Rough Trade Records. In 1989, the album was reissued with eight bonus tracks by Mute Records.
