The BSS data were collected in agrigultural soils from Northern
Europe. from an area of about 1,800,000 km2.
769 samples on an iregular grid were taken in two different
layers, the top layer (0-20cm) and the bottom layer.
This dataset contains the bottom layer of the BSS data.
It has 46 variables, including x and y coordinates.
