1.
An NP fertiliser free from Thomas slag, calcined phosphate, aluminium-calcium phosphate, partially solubilised rock phosphate and soft ground rock phosphate must be declared in accordance with solubilities (1), (2) or (3):
when the water-soluble P2O5 does not amount to 2 %, solubility (2) only shall be declared;
when the water-soluble P2O5 is at least 2 %, solubility (3) shall be declared, and the water-soluble P2O5 content must be indicated [solubility (1)].
The P2O5 content soluble in mineral acids only must not exceed 2 %.
For this type 1, the test sample for determining solubilities (2) and (3) shall be 1 g.
2 (a)
A NP fertiliser containing soft ground rock phosphate or partially solubilised rock phosphate must be free from Thomas slag, calcined phosphate and aluminium-calcium phosphate.
It shall be declared in accordance with solubilities (1), (3) and (4).
This type of fertiliser must contain:
at least 2 % P2O5 soluble in mineral acids only [solubility (4)];
at least 5 % P2O5 soluble in water and neutral ammonium citrate [solubility (3];
at least 2,5 % water soluble P2O5 [solubility (1)].
This type of fertiliser must be marketed under the designation ‘NP fertiliser containing soft ground rock phosphate’ or ‘NP fertiliser containing partially solubilised rock phosphate’.
For this type 2(a), the test sample for determining solubility (3) shall be 3 g.
Particle size of the basic phosphatic ingredients:
Thomas slagat least 75 % able to pass through a sieve with a mesh of 0,160 mm
Aluminium-calcium phosphateat least 90 % able to pass through a sieve with a mesh of 0,160 mm
Calcined phosphateat least 75 % able to pass through a sieve with a mesh of 0,160 mm
Soft ground rock phosphateat least 90 % able to pass through a sieve with a mesh of 0,063 mm
Partially solubilised rock phosphateat least 90 % able to pass through a sieve with a mesh of 0,160 mm
2 (b)
A NP fertiliser containing aluminium-calcium phosphate, must be free from Thomas slag, calcined phosphate, soft ground rock phosphate and partially solubilised rock phosphate.
It shall be declared in accordance with solubilities (1) and (7), the latter applying after deduction of the solubility in water.
This type of fertiliser must contain:
at least 2 % water-soluble P2O5 [solubility (1)];
at least 5 % P2O5 according to solubility (7).
This type of fertiliser must be marketed under the designation ‘NP fertiliser containing aluminium-calcium phosphate’.
3.
In the case of NP fertilisers containing only one of the following types of phosphatic fertiliser: Thomas slag, calcined phosphate, aluminium-calcium phosphate, soft ground rock phosphate, the type designation must be followed by an indication of the phosphate ingredient.
The declaration of the solubility of the P2O5 must be given in accordance with the following solubilities:
for fertilisers based on Thomas slag: solubility (6b);
for fertilisers based on calcined phosphate: solubility (5);
for fertilisers based on aluminium-calcium phosphate: solubility (7);
for fertilisers based on soft ground rock phosphate: solubility (8).
B.2.2.
Type designation:

Data on method of production:
Product obtained chemically without addition of organic nutrients of animal or vegetable origin and containing crotonylidene diurea or isobutylidene diurea or urea formaldehyde
Minimum content of nutrients (percentage by weight):
Total: 18 % (N + P2O5);
For each of the nutrients:
5 % N.
At least ¼ of the declared content of total nitrogen must derive from nitrogen form (5) or (6) or (7).
At least 3/5 of the declared nitrogen content (7) must be soluble in hot water,
5 % P2O5.
