Central Swedish lowland

[6] The region forms a belt of fertile soils suitable for agriculture that interrupts the forested and till-coated lands to the north and south.

[6][7] The soil types of the Central Swedish lowland include fine grained sediments, like clays, as patent materials.

This is because the whole region is below the highest coastline (Swedish: Högsta kustlinjen) since deglaciation, allowing for marine and lacustrine sedimentation before post-glacial rebound bought the lowland above sea level.

[8] Before the expansion of agriculture fertile soils were occupied by contiguous broad-leaved tree forest where maples, oaks, ashes, small-leaved lime and common hazel grew.

[B] The groundwater of the coast of the Central Swedish lowlands have high amounts of chloride as result of the presence of fossil sea water.
