Bodemkundig onderzoek in een aantal percelen langs de gasleiding in Meeden (Gr.)
In het najaar van 1965 heeft de N.V. Nederlandse Aardolie Maatschappij een gasleiding gelegd, o.m. door het dorp Meeden. Op de percelen is voor het leggen bronbemaling toegepast. De grondeigenaren stellen, dat door deze bronbemaling mogelijk schade is toegebracht aan hun landerijen
Vegetation and soil in a Drenthian brook valley (The Netherlands)
The soil spectra, based on the higher levels of soil classification according to De Bakker & Schelling (1966), are not attuned to semi‐natural vegetations in the study area, consisting of meadows. Only very general relations between soil‐ and vegetation spectra were found. It appeared that ground water fluctuation ranges were discriminating factors, the soil profile being especially related to water movements. Impermeable layers are very important in otherwise homogenous soil units. Ripening processes in different grades, recent or in the past, caused irreversible alterations and influenced the ground water regime. The picture of the relationship between soil and vegetation is often confused by former agricultural use affecting both the soil profile and the plant communities
