Chemical composition of the humus layer, mineral soil and soil solution of 200 forest stands in the Netherlands in 1995

A nationwide assessment of the chemical composition of the soil solid phase and the soil solution in the humus layer and two mineral layers (0-10 cm and 10-30 cm) was made for 200 forest stands in the year 1995. The stands were part of the national forest inventory on vitality, included seven tree species and were all located on non-calcareous sandy soils. The soils are nearly all characterized by high nitrogen and metal contents in the humus layer ans low pH and base saturation values in the minerallayer, indicating the occurrence of eutrophication, acidification and heavy metal pollution.
