Soil development of an anthropogenic filling with affects to soil properties.

The aim of this work is to determine the changes created by a covering anthropogenic in an area in the south of Bremerhaven, the port of Bremen, Germany. In 1973 it was started the construction of a highway connecting commercial purposes which required, however, the excavation of soil material that then had to be repositioned. The study area sees a field previously used for farming purposes, as a place designated to overlap: the Ahnthammsmoor lost its function and was upset in all the surface. The filler material necessarily involves physical changes (high, degree of compaction and level of ground water), chemical (addition of new organic material), ecosystemic (for the disruption of flora and fauna) and economic (loss of existing functionality ). The problem was then faced with environmental and soil investigation, going to recreate the scenario above the motorway construction and characterize the new 'artificial environment'.
