The aim of this study was to delineate management zones by using topographical data, and to investigate how these management zones relate to soil parameters and yield. Elevation, as well as soil and yield data, were sampled in the field. Digital elevation models have been created, and the topographical parameters of slope, aspect and drainage area, estimated. Management zones have been delineated by the use of threshold values and filtering. Significant differences between the zones with respect to organic matter, clay content, phosphorus, pH, potassium, magnesium and yield have been found. The results indicate that topographical data can be used delineate agricultural management zones in central Sweden.
