The Koekoekspolder is situated to the north of IJsselmuiden. It is a varied horticultural region where a host of crops are produced. The central location means we have a large market in the west of the country, but Germany is also an important market. We use our two greenhouses to grow cucumbers. Efficient use of energy is one of our priorities so our greenhouses are powered by a special combined heat and power system. We also use natural predators such as parasitic wasps and predatory mites to control pests and diseases. Biological crop control is a clean approach that has benefits all round.
