Neue Hypothesen zur Bodenbildung auf Quartärablagerungen der Nordostschweiz

[摘要] Our investigations on soils of the northeastern part of Switzerland lead to the foUowing conclusions:
1) Quaternary soils of different age can generally be separated by using the pH-values of the B-honzon. The validity ofthis method is restricted to topographic positions wherethere have been neither accumulation- nor erosion-processes.
2) There seem to be more textural inhomogeneities of theparent-material than previously supposed. Thus, soil development is often misinterpreted.
3) Special attention must be drawn to soil erosion on gravellymatenal. Otherwise, agricultural use of these soils canlead to irreparable damage within a Short time becausethe weathering rate in gravels is low. In contrast, soil erosion in forested areas may lead to a slight amelioration asthese soils are strongly acid and thus have a very lowbase-saturation.
