Literatuuronderzoek chrysantenteelt zonder stomen: Kan een monocultuur in een stabiel microbieel evenwicht blijven?

Chrysanthemum are grown in a soil-based cultivation with 4-6 cultivation cycles per year. The build-up of diseases and pests in the soil is considerable. It is now common to steam the soil at least once a year. The related energy consumption is 4-6 m3 gas per m2 per year. The build-up of diseases is associated with hygiene, the cuttings, the press pots on which chrysanthemum cuttings are grown, the transition from propagation to cultivation medium, irrigation cycles and tilling root residues and press pots into the soil after cultivation. Major diseases and pests are Pythium, Fusarium, nematodes and Thrips. This literature study describes what is known about cultivation circumstances promoting diseases and pests. The aim was to assess the feasibility of a chrysanthemum crop without steaming based on adaptations of the current cultivation method.
