PRESCRIBED DESCRIPTIONS OF MATERIAL, MEANINGS OF NAMES, PARTICULARS AND INFORMATION TO BE CONTAINED IN THE STATUTORY STATEMENT AND LIMITS OF VARIATION

    Limits of variation
        1.    The limits of variation prescribed in this Schedule shall be the permitted deviations of the measured from the declared content of a nutrient, secondary nutrient or trace element, or of the measured from the declared neutralising value, or of the measured from the declared amount of material passing through a specified sieve.
        2.    Save as prescribed in paragraphs 6, 7 and 8, the limits of variation shall be those set out in the fifth column of the following table.
        3.    In Section B and Group 2 of Section C of the following table the negative limits of variation specified individually for N, P2O5 and K2O are those permitted for each nutrient taken separately and the limits of variation for the total nutrient content of a fertiliser shall be the sum of the negative deviations from the declared content.
        4.    No limits of variation shall be permitted in respect of the minimum and maximum contents specified in the third column of the following table, save those prescribed in paragraph 6.
        5.    Where no maximum limit is specified in the third column of the following table, no limits of variation are prescribed as respects an excess of nutrient, neutralising value or amount of material passing through a specified sieve above the declared value or amount, save those prescribed in paragraph 7(b).
        6.    In the case of materials in Groups 1 to 4 of Section B and Group 2 of Section C of the following table which, not being designated as EEC fertilisers, are sold or offered for sale, and where the declared content of one or more of the nutrients falls below the following levels:

      (i)  in the case of nitrogen (N) — 2.5% in an NPK fluid fertiliser solution and 3.5% for all other fertilisers and

      (a)  except as provided in sub-paragraph (b) of this paragraph, the limit of variation shall be one-tenth of the overall content of the nutrient concerned, with a maximum of 2 % by weight:
    Provided that the overall content of that nutrient remains within:

      (ii)  the limits of variation specified in the fifth or, where appropriate, the sixth column of the said table.

      (b)  in the case of materials in Group 1(c) of Section A and Groups 1, 2, 3, 5 and 6 of Section B and Groups 1(d), 2, 3 and 4 of Section C of the following table which, not being designated as EEC fertilisers, are sold or offered for sale, the limits of variation of ureic nitrogen when declared at 10 % and above shall be plus or minus 1.5 % by weight and when declared below 10% shall be plus or minus 1.0% by weight.
        8.    The limits of variation for trace elements and secondary nutrients other than where prescribed in Sections D and E of the following table shall be:

      (i)  trace elements — up to one-fifth of the declared value for a trace element content not exceeding 2% and 0.4% in absolute terms for a content of more than 2%;

      (ii)  secondary nutrients in the oxide form — up to a quarter of the declared value for a secondary nutrient content not exceeding 3.6% and 0.9% in absolute terms for a content of more than 3.6%. This is equivalent to the following maxima for the elemental forms—
