Division 2 A solid organo-mineral fertiliser shall contain at least one of the following declared primary nutrients: nitrogen (N), phosphorus pentoxide (P2O5) or potassium oxide (K2O).

Where a solid organo-mineral fertiliser contains only one declared primary nutrient, that nutrient content shall be at least the following:

1. (a)

   2,5 % by mass of total nitrogen (N), out of which 1 % by mass shall be organic nitrogen (N_org),

2. (b)

   2 % by mass of total phosphorus pentoxide (P₂O₅), or

3. (c)

   2 % by mass of total potassium oxide (K₂O).

Where a solid organo-mineral fertiliser contains more than one declared primary nutrient, those nutrient contents shall be at least the following:

1. (a)

   2 % by mass of total nitrogen (N), out of which 0,5 % by mass shall be organic nitrogen (N_org),

2. (b)

   2 % by mass of total phosphorus pentoxide (P₂O₅), or

3. (c)

   2 % by mass of total potassium oxide (K₂O).

The sum of those nutrient contents shall be at least 8 % by mass.
