An ingredient in a mixture of fertilisers, or a single fertiliser which contains more that one of the chemical elements on which the subdivision is based, is classified only in the first of the appropriate places. 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.
Information relative to the form in which the fertilizer is presented, e.g. granulation, coating, etc. is always given in addition to the chemical composition of the fertilizers.
Any ingredient in a mixture, which is considered to present information of interest for search, is also classified using a combination of classification symbols. If a document concerns embodiments comprising mixtures whose elements are covered individually by different subclasses, groups or subgroups, the document is classified with a Combination-set.
The following rules apply:
- The first element of the Combination-set corresponds to the first relevant (sub)group mentioned in the classification scheme independently of the importance or relevance of the element in the whole fertilizer mixture;
- the following element or elements of the Combination_set are added sequentially in the order in which they appear in the classification scheme to the first element using a ",".
In this place, the following terms or expressions are used with the meaning indicated:
Fertiliser (fertiliser material) | Natural or artificial substance containing the chemical elements that improve growth and productiveness of plants. |
In patent documents, the following words/expressions are often used as synonyms:
- "fertiliser" and "plant nutrient "
- "Amendment", "Plant food", "Agricultural chemical" and "Fertiliser"
In patent documents, the following words/expressions are often used with the meaning indicated:
"enrichment" | "fertiliser" |
"soil amendment" | " composition capable of modifying the chemical (pH) or physical (structure) condition of soils for agricultural purposes". |
This place covers:
Fertilisers made from whole animal corpses; from parts of animals which can not be more specifically classified in the subgroups of this group, such as non differentiated processes for treating fish or meat or animal derived materials; fertilisers from general materials such as proteinaceous materials and animal material not further specified.
This place does not cover:
Fertilisers from animal excrements |
Mixtures of these fertilizers with other fertilizers belonging individually to other groups of the classification will be given a Combination-set as explained under the Note for class C05.
This place covers:
Fertilisers from animal excrements, manure, liquid manure, etc.
This place does not cover:
Fertilisers from waste water, sludge or similar masses | |
Processing liquids by a fermentation step | |
Treating manure |
Documents relating to a manure composition or process for its preparation in combination with an apparatus for obtaining thereof are classified as the Combination-set (C05F 3/00, C05F 3/06 ).
Mixtures of these fertilizers with other fertilizers belonging individually to other groups of the classification will be given a Combination-set as explained in the Note under C05.
This place covers:
Apparatus for the manufacture of fertilisers from excrements of animal or human origin.
Closets for human excrements are classified under A47K 11/00.
Treatment of animal manure is classified under A01C 3/00.
This place does not cover:
Apparatus for composting excrement |
- Apparatus to manufacture fertilisers are classified primarily in the corresponding groups of the C05 field.
- All information contained in a document, claims but also examples or other part of the description can be classified if they are considered to contain relevant information in the field.
- Group C05F 3/06 covers all apparatus for the manufacture of fertilisers from excrements of animal or human origin.
- Since the group has no further subdivisions all documents relating to these sorts of apparatus should be classified in this group.
- If the structure of the apparatus contains technical details relevant for classification in other fields, extra symbols in other relevant fields might be given. This group is non-limiting, i.e. it is possible to have documents classified here and in other relevant groups.
As an example, a bio-mass processing system wherein one or more mixers, mixes a bed of bio-mass material such as manure in a defined length and width portion of the bed, in a dryer, is classified in C05F 3/06 but also in F26B 9/00 (machines or apparatus for drying solid materials) and F26B 23/00 (heating arrangements).
This place covers:
This group covers processes for producing fertilizers from waste water, sewage sludge, sea slime, ooze or similar masses, and the corresponding products
Attention is drawn to the following places, which may be of interest for search:
Methods or installations for de-watering, drying or incineration of sewage sludge |
This place covers:
Fertilisers from wastes from human settlements, garbage, waste paper etc.

This place does not cover:
Fertilisers from town/sewage sludge |
Mixtures of these fertilizers with other fertilizers belonging individually to other groups of the classification will be given a Combination-set as explained under Note for class C05.
Fertilisers from town refuse treated by a fermentation process should always be given a classification in C05F 17/00.
This place covers:
Composted material per se obtained from household waste or any other source where no pertinent class exists in C05F 17/00.
This place does not cover:
Preparation of fertilizers from household or town refuse characterised by the composting step |
When a fertiliser mixture contains mature compost as one of its components, the subgroup C05F 9/04 should be given in combination to the groups corresponding to other components of the fertiliser in order to indicate the presence of compost material in the mixture.
This place covers:
Fertilisers from organic products, natural or synthetic, not covered by any of the previous classes.
Some examples of materials belonging to this class are wood products such as bark or sawdust, fibrous materials, polymers, seaweeds.
