A comprehensive data set demonstrating the spatial variability of soil properties at field scale

The data set contains information about soil properties at 80 grid points of a 20 ha large agricultural used field in North Rhine-Westphalia. Each grid point was mapped and sampled up to the soil depth of 90 cm. Over a period of four years (1999 to 2002) soil analysis was conducted considering soil moisture and mineral nitrogen content before sowing and after harvest. Basic information about agricultural management, soil texture, soil organic carbon and annual yield are included.
