The answer is always mandatory. If the farmer uses only certified seed, it should be specified in table D.3 of the AGNAS form together with the information on all agricultural parcels of land owned by him.
Instead of filling in the form, a farmer can send a letter or an e-mail containing his full name, the address, the area of agricultural land possessed and the following statement:
„During … (season, year) I did not use the harvested material as sowing material (FSS)” or „During … (season, year) I used only certified seed”.
Please do not send photocopies of the invoices. It is not a sufficient response to the requests (the fact that a farmer sowed certified seed does not mean that he did not use the harvested material as well).
