Abstract
The experimental field, which has been installed by Dr. W. Lüdi on the Schynige Platte in 1930, has been reconstructed and permanently marked. It includes 340 single plots, where different combinations of fertilization and cultivation had been tested up to the fifties. From 1988 to 1990 new data had been recorded. Together with the existing data, they were organized in a data bank. From this data bank, methods for graphic, statistic and other interpretation were developed.
