Information for farmers is primarily provided on the website of Skal in Dutch language. Dutch organic farmers may use products from the Dutch inputs list. If they use a product not listed there, they have to prove during inspection that the use of the product is allowed, otherwise it will be treated by Skal as a non-conformity.
Farmers may search for approved inputs in the product search section. Information on this website is displayed in English. The Dutch version can be found on the Skal website.
