Soil quality is threatened by traffic with modern agricultural machinery. The PredICTor project had as its main deliverable an online decision support tool for assessing the risk of compaction for an intended field traffic situation (Terranimo®). Terranimo® is a web-based computer model primarily designed for farmers, agricultural contractors, consultants, and enforcement authorities, but has scientific applications as well. Terranimo® can help in optimising the use of agricultural machinery in the field and in preventing damage to the soil structure by indicating conditions under which there is a high risk of harmful compaction. The tool exists in two versions that can be accessed at www.terranimo.dk and www.terranimo.ch, respectively. The former version can be run in eight languages and provides access to six national sub-versions with their respective typical default soil types (Denmark, Norway, United Kingdom, France, Belgium-Flanders and Finland). In addition, a sub-version provides typical FAO-defined soil types. Since the summer of 2013, the latter version of Terranimo® has been the official tool in Switzerland for evaluating the soil compaction risk in the scope of the “Soil Protection in Agriculture” implementation guidance of the Federal Office for Agriculture (FOAG) and of the Federal Office for the Environment (FOEN). The potential use of Terranimo® in policy options to mitigate the soil compaction threat was mentioned in a policy brief recently produced at the conclusion of the EU project RECARE (https://www.ecologic.eu/sites/files/publ ication/2018/2730_recare_subsoilcompaction_ web.pdf). The Terranimo® websites have been visited by more than 15,000 users in 2018 (~6,500 and ~9,000 for the .dk and .ch versions, respectively).
