Seed Test Price lists are sent out when anticipated seed processing is booked. We use independent Licensed Seed Laboratories that are the most cost-effective, appropriate, and reliable for the individual crop you wish to have tested.

The results are sent to Goldingham Contracts, so that we can discuss them with you, and then make an appropriate arrangement to clean and treat your seed when it is convenient for you.
