In the Netherlands most crops grown in greenhouses reuse drain water. However, in the cultivation of amaryllis
cut flowers (Hippeastrum) little drainage water is being reused so far because of strong suspicions of inhibitory
substances in the drainage water. To reduce the emission of nutrients to the environment an experiment was
started on request of the amaryllis growers. In a greenhouse experiment drainage water of amaryllis was treated
with advanced oxidation and reused. This was compared with the reuse of drainage water treated with an UV
disinfector and a control treatment without the reuse of drainage water. In three years of cultivation, there was
no difference in production and no adverse effects were seen in crop growth. This research was funded by the
Dutch amaryllis growers, the ‘Topsector Tuinbouw en Uitgangsmaterialen’, the Product Board for Horticulture, the
project ‘Samenwerken aan Vaardigheden’ and Koppert.
