The Muencheberg Soil Quality Rating (SQR) was developed by the Leibniz Centre for Agricultural Landscape Research (ZALF). SQR describes the suitability of sites under agricultural land use and helps to estimate the yield potential of sites at a global scale. This method was especially adapted for application with soil maps by the Federal Institute of Geosciences and Resources BGR and is published in the documentation of Ad-hoc-AG Boden (representing the soil experts of the geological services of the German federal states). The map shows the SQR for cropland in Germany based on the landuse stratified soilmap of Germany at scale 1:1,000,000. Climate (DWD), Relief (BKG) and landuse data (CLC2006) are used as input data in addition to the soil map. SQR consists of a series of pedotransfer rules. First, eight basic soil properties are weighted and combined to describe the soil (substrate, rooting depth, etc.). Next, hazard indicators are derived (drought risk, soil depth above solid rock). These indicators are critical for farming and limit the overall soil quality. Only those hazard indicators were selected for SQR which have the greatest effect on potential grain yield. The final SQR-score ranges from about 0 to 102 points.
