The genesis took mainly place during the Wnrm glaciation; the Rhine and Meuse were braided rivers, depositing gravelly and sandy materials. During the degeneration of these rivers, more sandy and loamy deposits originated, the 'Hochfflutlehm', mainly pre-Allerod. From the Meuse valley sands were blown eastwards (Preboreal and Boreal), forming a broad area of inland dunes. In the Boreal the transition to a meandering system took place and Holocene deposits replaced the 'loams'.
The results of the survey allowed propositions on reclamation and improvement of drainage and soils. Suitability for crop production was derived from the soil maps, farmers' experience, yield figures and rental values. The landscape was dated by pollen analysis of peaty layers.
