| Popis: | In the Netherlands, the government and horticultural industry have agreed to lower the emission of nutrients to the environment. To reduce the emission of fertilizers in pot orchid cultivation research into the effects of reusing drainwater (recirculation) in Phalaenopsis was conducted at Wageningen UR Greenhouse Horticulture. The first treatment aimed to lower the emission to the standard of 2018. In the second treatment the emissions were lowered even more to meet the more stringent standards after 2018. Both treatments were compared with a third treatment without reuse of drain water. Sodium and zinc content increased in both recirculation treatments. The reuse of drainage water has shown no adverse effects on plant growth or disease incidence. In all treatments, virtually no plants were lost. |
