Abstract New cultivation systems should be easy to disinfect and not susceptible to pests and diseases. There are, therefore, three system disinfection methods tested. Of these, soil steaming was the quickest, cheapest and most effective in the shallow substraatbed. Soil resetting follows in second place owing to the higher cost and relatively longer treatment time. In the deep soilbeds, soil resetting is most effective. The cost is higher and the treatment time is longer than for soil steaming or culture cooking. Cultural Cooking is difficult to implement in the deep soilbed, but results in a good control of Verticillium in the shallow and the deep beds. An improvement of the level of suppressiveness against trips may be achieved with aid of mulch layer or breeding tanks for predatory mites. Applying the mulch layer improved the establishment of predatory mites. The breeding tanks caused a sharp increase. However, both methods do not lead to fewer trips. For resistance to Pythium is a large pore volume, the capacity of the substrate to carry bacteria and a high acidity (pH> 7) important. The sand that is now used in the shallow substrate bed is conducive for Pythium. The economic analysis shows that for chrysanthemum, freesia and lisianthus, the sand and soil beds may have an acceptable cost up to three percent.
