(i) Expert knowledge based and reliable - scientific approach should be implemented as much as possible without restriciting the user-friendliness. Finally a reliable evaluation for any environmental question is not possible without expert knowledge.
(ii) Easy to use and applicable therefore an electronic version is available.
(iii) Flexibility the adaptations to e.g. different environment, planning practices, methods for soil description and legislations are realised.
(iv) Cost efficiently the B-level is developed to allow soil evaluation without sufficient resources for soil mapping
(v) Upgradeability - specific modules could be added (e.g. specification to land use or to the soil strategy of the European Union).
(vi) Educative introducing chapters are given to inform planners without much experience in soil evaluation.
The TUSEC-manual refers to particularities of urban soils as disturbance, layering, compaction, artefacts, high content of coarse material and high content of organic matter. Clear progress was achieved in points of accuracy of the evaluation for typical urban soils but also for a wide range of natural soils. Nevertheless the restrictions and potentials of such easy-to-use-methods has to be analysed.
