Summary
The data set contains data about soil hydrological properties of North East and Central German soils. Included are measured data of the soil water retention curve and the unsaturated hydraulic conductivity function. Information to geo reference, soil type and horizon are given. Additional soil physical data like particle size distribution, dry bulk density, organic matter content and other variables are presented and its measurement is methodically described. The data base includes original measurement results of 497 mineral soil samples from 77 sites. The mineral soils cover a wide range of texture classes and dry bulk densities.
