A robust hygiene protocol for the crop changeover requires a well-conceived plan, precise scheduling and ample time. Cleaning and disinfecting the greenhouse and the operational areas is crucial. Growers can seek advice from a consultant who is famil ...

Pcfruit stelde een technische fiche samen met een stappenplan voor het opzetten van een Johnson-Su compost. Er wordt beschreven welk materiaal je nodig hebt en hoe je te werk gaat. Deze fiche werd opgemaakt binnen het demonstratieproject Regeneratiev ...

De resultaten van Bemest op z’n Best zijn recent gepresenteerd. Twaalf kansrijke innovaties zijn uitvoerig onderzocht. Een baanbrekende nieuwe manier van bemesten zat er niet tussen, wel vier technieken die ver genoeg zijn om in de praktijk te testen ...

For the first time, all the relevant research on green light has been analysed. Partially replacing red/blue or white LEDs with green increases water use efficiency at leaf level by 15%. This finding is leading to further research. Other effects incl ...

The growing Fusarium problem is the result of a complex web of factors. According to experts, there are still many unanswered questions. The solutions will need to take an integrated approach, based on stricter hygiene protocols, good climate control ...

Hydrophilic glass coatings and film ensure higher light transmission when the greenhouse roof is wet due to condensation in the winter months, according to recent research. Some treatments also allow more light through in dry conditions. The degree o ...

Growing resistant varieties reduces the need for chemical crop protection. All plants possess basic defences against harmful fungi, but targeted control of a specific pathogen requires more, namely recognition of characteristic fungal proteins. Effec ...

Alternative sources of C02 will be needed in the years ahead. Capturing it from outdoor air is one possibility, although the technologies available have been developed outside the greenhouse horticulture sector. WUR will be trialling various systems ...

The Remote Precision Growing project is exploring how greenhouses can be managed more intelligently using sensors and KPls. Rather than relying on a single sensor unit for the entire greenhouse, the research team is steering the crop based on smaller ...

Dirk Mermans is the first grower in the Benelux region to install low-e glass in his new greenhouse in Wommelgem, Belgium. The effect of the glass is currently being scientifically studied, but the ornamental grower is already noticing the difference ...
