The National Rural Network has provided clarifications on eco-scheme 4 regarding biennial rotations. Arable crops are divided into three groups, with multi-year crops fulfilling the commitment if they remain on the same parcel for two years. Secondary crops from June 1 to November 30 must also be implemented for at least two years. Additionally, the use of pesticides is not allowed on leguminous and forage crops, while the use of integrated defense techniques or organic production is permitted on renewal crops. Checks will be based on the company register of cultivation operations, and the management of crop residues is allowed for non-livestock farms adopting conservative soil management techniques.
