Note(s)

  1. An ingredient in a mixture of fertilisers, or a single fertiliser which contains more than one of the chemical elements on which the subdivision into sub-classes is based, is classified only in the first of the appropriate sub-classes. Thus, a nitrophosphate or an ammoniated superphosphate is classified in C05B but not in C05C, magnesium phosphate is classified in C05B but not in C05D, and calcium cyanamide in C05C but not in C05D.
  2. In this class it is desirable to add, in conformity with paragraph 61 of the Guide, after the double oblique stroke the symbols relating to complementary information concerning individual constituents of an invention unit which is already classified as such. This complementary information concerns the indication of ingredients of a mixture of different fertilisers or of fertilisers with non-fertilisers.
 C05B
PHOSPHATIC FERTILISERS

 C05C
NITROGENOUS FERTILISERS

 C05D
INORGANIC FERTILISERS NOT COVERED BY SUB-CLASSES C05B, C05C; FERTILISERS PRODUCING CARBON DIOXIDE

 C05F
ORGANIC FERTILISERS NOT COVERED BY SUB-CLASSES C05B, C05C, e.g. FERTILISERS FROM WASTE OR REFUSE

 C05G
MIXTURES OF FERTILISERS BELONGING INDIVIDUALLY TO DIFFERENT SUB-CLASSES OF CLASS C05; MIXTURES OF ONE OR MORE FERTILISERS WITH MATERIALS NOT HAVING A SPECIFICALLY FERTILISING ACTIVITY, e.g. PESTICIDES, SOIL CONDITIONERS, WETTING AGENTS (organic fertilisers containing added bacterial cultures, mycelia, or the like C05F 11/08; organic fertilisers containing plant vitamins or hormones C05F 11/10)
