Only the numbers stating the contents of the major and secondary elements covered by Directive 76/116/EEC shall follow the type designation. Where several trace elements are present they shall be listed in the alphabetical of their chemical symbols: B, Co, Cu, Fe, Mn, Mo, Zn; (c) the guaranteed content in respect of each nutrient and the guaranteed content expressed as forms and/or solubilities where these are specified in the Annexes to Directive 76/116/EEC and, for each trace element present, as required by Article 6; (d) where all or part of the trace element is chemically linked with an organic molecule, the name of that element is then followed by one of the following qualifiers: - 'chelated by . . .' (name of chelating agent or its abbreviation as set out in Chapter E (1) of the Annex), - 'complexed by . . .' (name of complexing agent as set out in Chapter E (2) of the Annex). The trace-element content shall be expressed as a percentage by weight, in whole numbers or where necessary to one decimal place for fertilizers containing only one trace element (Chapter A of the Annex). Where fertilizers contain several trace elements the number of decimal places may, for a given element, be as set out in Chapters B, C and D of the Annex. Trace-element content shall be expressed both in words and by the appropriate chemical symbols. The following shall be entered on the label or accompanying papers, with regard to the products appearing in Chapters A and B of the Annex below the obligatory or optional declarations: 'To be used only where there is a recognized need. Do not exceed the appropriate dose rates.'
