    1. CcHhClclNnNanaOoPpSs without nitrification,
    2. Type designation and composition of the nitrification inhibitor
    3. Description of nitrification inhibitors with which mixtures are allowed
    4. To allow greater access to the agronomic and environmental benefits of nitrification or urease inhibitors, the use of nitrification or urease inhibitors should be allowed for most types of nitrogen fertilisers, and more types of inhibitors should be allowed.
    5. Other types of EC fertiliser may contain nitrogen in a different form for which nitrification inhibitors are not effective.
    6. A list of authorised nitrification and urease inhibitors should therefore be introduced in Annex I to Regulation (EC) No 2003/2003.
    7. New nitrification inhibitors or urease inhibitors may be included in the Tables F1 or F2 respectively after evaluation of the technical files submitted in accordance with guidelines to be elaborated for these compounds.
    8. Fertilisers to which a nitrification inhibitor listed in Table F.1. has been added shall have the words “with nitrification inhibitor ([type designation of nitrification inhibitor])” added to their type designation. Fertilisers to which a urease inhibitor listed in Table F.2. has been added shall have the words “with urease inhibitor ([type designation of urease inhibitor])” added to their type designation. Technical information, as complete as possible, must be provided with each package or bulk consignment by the person responsible for marketing. This information must enable the user in particular to determine the rates and timing of application in relation to the crop being grown. New nitrification inhibitors or urease inhibitors may be included in the Tables F1 or F2 respectively after evaluation of the technical files submitted in accordance with guidelines to be elaborated for these compounds.
    9. In particular geographical or climatic conditions and particularly in cases of low water temperature and of reduced nitrification or where the competent authority can prove that there are no harmful consequences for the balanced development of the fish population, Member States may fix values higher than 1 mg/l.
