We wash the soil and soil-borne diseases from the seed potatoes without the use of pesticides.

We usually do the bio washing for the organic growers from Flevoland, but also a number of others outside. The disinfection with ozone gas is a natural method that works well for killing bacteria and fungi on the seed potatoes.


Good for the environment

The water we use to wash the seed potatoes is recycled. After the recycling process, we store the water in large basins to be used again. The sludge that remains is removed.
