2.2.1.3 Inorganic macronutrient fertilisers PFC 1(C)(I)

1 The pol­lut­ants in in­or­gan­ic mac­ronu­tri­ent fer­til­isers may not ex­ceed the fol­low­ing lim­it val­ues:

Pol­lut­ant

Lim­it val­ues in mil­li­grams per kilo­gram of dry mat­ter

Lim­it val­ues in mil­li­grams per kilo­gram of phos­phor­us (P)

Ar­sen­ic (As)

40

Cad­mi­um (Cd) in fer­til­isers with a phos­phor­us con­tent (P) of 1 % or less

3

Cad­mi­um (Cd) in fer­til­isers with a phos­phor­us con­tent (P) of over 1 %

50

Chro­mi­um (Cr)

2000

Hexa­valent chro­mi­um (Cr VI)

2

Cop­per (Cu)

600

Mer­cury (Hg)

1

Nick­el (Ni)

100

Lead (Pb)

120

Va­na­dium (V)

4000

Zinc (Zn)

1500

Per­chlor­ate (ClO4-)

50

The lim­it val­ues for cop­per (Cu) and zinc (Zn) do not ap­ply if these ele­ments have been de­lib­er­ately ad­ded to the in­or­gan­ic mac­ronu­tri­ent fer­til­iser to rem­edy a trace nu­tri­ent de­fi­ciency in the soil and this is de­clared in ac­cord­ance with the la­belling re­quire­ments.

2 The Bi­ur­et (C2H5N3O2) con­tent in or­gan­ic-min­er­al fer­til­isers must not ex­ceed 12g/kg of dry mat­ter.

3 In sol­id in­or­gan­ic simple or com­pound mac­ronu­tri­ent am­moni­um ni­trate-fer­til­isers with a high ni­tro­gen con­tent (PFC 1(C)(I)(a)(i)(A) and PFC 1(C)(I)(a)(ii)(A)), the cop­per (Cu) con­tent may not ex­ceed 10 mg/kg and the chlor­ine (Cl) con­tent 200 mg/kg.
