MANUFACTURE OF FERTILISERS

|  | C05 |
Note(s) 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 Fulltext... Hierarchy... Expanded...C05B but not in Fulltext... Hierarchy... Expanded...C05C, magnesium phosphate is classified in Fulltext... Hierarchy... Expanded...C05B but not in Fulltext... Hierarchy... Expanded...C05D, and calcium cyanamide in Fulltext... Hierarchy... Expanded...C05C but not in Fulltext... Hierarchy... Expanded...C05D. 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.
