# The Fertilisers Regulations (Northern Ireland) 1992, Paragraph 8: Limits of variation


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—
0.64% maximum for Ca
0.55% maximum for Mg
0.67% maximum for Na
0.36% maximum for S.
