Abstract

Based on experimental data from wheeling experiments, a web-based model for the simulationof stress and the evaluation of the soil compaction risk under agricultural machinery namedTerranimo® has been developed. Terranimo® incorporates a model for prediction of contactarea, shape and stress distribution in the tyre-soil interface from wheel load and readily-availabletyre parameters and the topsoil strength. In Terranimo® pedotransfer functions are usedto estimate soil strength from clay content and matric potential. Principally, by limiting theimposed stress to below soil strength, the risk of soil compaction and undesirable changes ofsoil structure - and hence soil functions - can be minimized.
