Composition of elements in soil samples around the Baltic Sea

Description

This data originates from a geological survey on the composition in agricultural soils from 10 countries surrounding the Baltic Sea. Top soil (0-25 cm) and bottom soil (50-75 cm) samples from 768 sites were analysed. This data frame contains the measurements corresponding to the total concentration of four elements in the top soil samples.
