Fertiliser records
If you run an agricultural business in the Netherlands, you must keep an administration with regard to your manure policy. Depending on the area of your business and the quantity of manure that you supply or produce, you must keep track of data about the production, supply, disposal and use of fertilisers. How you do this is up to you. It is important that you retain documents which support your records. These documents must be retained for a period of at least 5 years.
