For the purposes of Article 63(2) 3^rd subparagraph of Regulation (EC) No 1782/2003, Member States shall establish the set-aside rate by using the data available related to the land concerned.

The number of hectares corresponding to the set-aside entitlements allocated in the first year of application of the single payment scheme shall not vary by a margin of more than 5 % of the average number of hectares set aside in the reference period.

Where the margin referred to in the first subparagraph is exceeded, the number of hectares shall be adjusted by 1 August of the first year of application of the single payment scheme at the latest. However, the set-aside obligation related to the new set-aside payment entitlements shall apply to the farmer concerned only starting from the following year.
