Today there are around 2000 members, and its headquarters have been in Göttingen since 2012 (before that in Oldenburg). The bi-annual meeting of the DBG is the most important platform of German-speaking areas for the exchange of new findings in soil science.
The outcrops of the Trossingen Formation are characterized by so-called “hummocky” meadows. It forms very heavy soils (minute soil), which can be recognized by typical tree growth (crooked and leaning trees), and is prone to frequent landslides after rainfall. [3] Tuberous marl landscapes can often only be used for orchards. [2]
The surface geology of Germany has evolved to its current configuration due to regional differences in the action and appearance of external and internal forces during the last c. 20 million years. Germany can be divided into three physiographic regions: the Central European Depression, the Central European Blocks and the Alps.
Friedrich Albert Fallou (1794–1877) was the German founder of modern soil science. [1] While working as a lawyer and tax assessor, [2] [3] Fallou established himself as an independent scientist, a recognized authority [4] in the natural history of farm and forest soil. In 1862 he advanced the idea that soil was separate in nature from geology.
Soil Profile on Chalk at Seven Sisters Country Park, England. Pedology (from Greek: πέδον, pedon, "soil"; and λόγος, logos, "study") is a discipline within soil science which focuses on understanding and characterizing soil formation, evolution, and the theoretical frameworks for modeling soil bodies, often in the context of the natural environment.

A stonelayer, or soil stonelayer, or stone line, is a three-dimensional subsurface layer, or soil horizon, dominated by coarse particles (>2mm), that generally follows (mimics) the surface topography (Sharpe 1938).
American soil scientist Hans Jenny published in 1941 [128] a state equation for the factors influencing soil formation: S = f(cl, o, r, p, t, ...) S soil formation; cl (sometimes c) climate; o organisms (soil microbiology, soil mesofauna, soil biology) r relief; p parent material; t time; This is often remembered with the mnemonic Clorpt.
A represents soil; B represents laterite, a regolith; C represents saprolite, a less-weathered regolith; beneath C is bedrock. Saprolite is a chemically weathered rock. Saprolites form in the lower zones of soil profiles and represent deep weathering of the bedrock surface. In most outcrops, its color comes from ferric compounds.
