PART IIU.K. REQUIREMENTS RELATED TO PFCS
PFC 1(C)(I): INORGANIC MACRONUTRIENT FERTILISERU.K.
1.An inorganic macronutrient fertiliser shall be aimed at providing plants or mushrooms with one or more of the following macronutrients:U.K.
(a)
primary macronutrients: nitrogen (N), phosphorus (P) or potassium (K),
(b)
secondary macronutrients: calcium (Ca), magnesium (Mg), sodium (Na) or sulphur (S).
2.Contaminants in an inorganic macronutrient fertiliser must not exceed the following limit values:U.K.
(a) cadmium (Cd)
:
(i)
where an inorganic macronutrient fertiliser has a total phosphorus (P) content of less than 5 % phosphorus pentoxide (P2O5)-equivalent by mass: 3 mg/kg dry matter, or
(ii)
where an inorganic macronutrient fertiliser has a total phosphorus (P) content of 5 % phosphorus pentoxide (P2O5)-equivalent or more by mass (‘phosphate fertiliser’): 60 mg/kg phosphorus pentoxide (P2O5);
(b) hexavalent chromium (Cr VI)
:
2 mg/kg dry matter,
(c) mercury (Hg)
:
1 mg/kg dry matter,
(d) nickel (Ni)
:
100 mg/kg dry matter,
(e) lead (Pb)
:
120 mg/kg dry matter,
(f) arsenic (As)
:
40 mg/kg dry matter,
(g) biuret (C2H5N3O2)
:
12 g/kg dry matter,
(h) perchlorate (ClO4-)
:
50 mg/kg dry matter.
3.The copper (Cu) content in an inorganic macronutrient fertiliser must not exceed 600 mg/kg dry matter, and the zinc (Zn) content in an inorganic macronutrient fertiliser must not exceed 1 500 mg/kg dry matter. However, these limit values shall not apply where copper (Cu) or zinc (Zn) has been intentionally added to an inorganic macronutrient fertiliser for the purpose of correcting a soil micronutrient deficiency and is declared in accordance with Annex III.U.K.
