Malm
Category:
geology
“Malm” describes a soft, pale, workable soil.
Field Description
Crumbly, light-coloured earth, often easily cultivated compared to harder chalk.
In White’s Landscape
Malm soils supported agriculture and formed gentler slopes between more resistant geological layers.
Notes
The contrast between malm and “rag” reflects practical land use as much as geology.
