Promising results from first field trials
In collaboration with Biobest and Boerennatuur Vlaanderen, the first trials started in 2021. These aimed to attract more natural enemies to crop fields by planting targeted flower margins, with funding from the port’s Agricultural Innovation Fund. Trials were conducted on a local farm in Kieldrecht. Onions being a common crop, the introduction of flower margins proved effective in reducing the need for crop protection against thrips. Initial results showed that insecticides could be avoided without compromising pest control or crop yield.
Native flowers and economic analysis across three crops
During the project, specific native flower species are selected for the margins to attract natural enemies in corresponding crops, with consideration for soil types. Trials are conducted in at least three crops: sugar beet, onions, and fennel. A minimum of 2 km of flower margins is planted, each 6 meters wide (totaling 1.2 ha). These margins are closely monitored for species composition, populations of beneficial and pest insects, weed management, and maintenance. Costs and benefits are recorded to conduct a detailed economic cost-benefit analysis. Together with the farmers, Biobest monitors the flower margins and adjacent fields. Monitoring protocols are developed for each crop, which can later be used directly by the farmers themselves.
Linking with the Kiekendief-Project for wider landscape impact
Randenrijk is also connected to the Kiekendief-Project, led by the Flemish Agency for Nature and Forest (ANB). Within this project, 90 hectares of kestrel-friendly crops are established in long-term collaboration with farmers. These include crops beneficial to both kestrels and farmers, forming a six-year rotation of alfalfa, grains, and other agroecological crops. In addition, permanent field margins and small shrubs are planted. Randenrijk facilitates knowledge exchange with the Kiekendief-Project, and one of the margins next to a grain field in that project is also monitored by Biobest.
Advice and demonstrations for farmers in the Wase Polder
Communication plays a key role in the success of this societal project around the Waasland Port. It is essential to actively engage and inform farmers in the Wase Polder about the benefits and practical implementation of FAB. By consolidating and sharing existing knowledge with all stakeholders, farmers are better equipped to make informed decisions about sowing and managing flower margins. Tailored advice will be provided to 15 interested farmers to help them effectively apply FAB practices on their fields. Demonstration events held during the project will serve as platforms to share trial results and inspire farmers to adopt sustainable agricultural methods. Through a transparent and participative communication approach, all stakeholders can contribute to a more sustainable and biodiverse future for the region. Policy recommendations based on the results of the monitoring and cost-benefit analysis will also be shared to help refine agricultural subsidy schemes where needed.
Sharing stories with citizens and regional partners
Beyond farmer involvement, it is also important to inform the broader community through local press, public information sessions, and existing sustainability initiatives. By sharing stories from the landscape and highlighting the role of flower margins and biodiversity, citizens can be inspired and become more involved in the projects around the Waasland Port. These efforts also help enhance the public image of agriculture. For communication aimed at the wider Waasland community, we collaborate with Grenspark Groot Saeftinghe and Maatschappij Linkerscheldeoever.
