Description

C05D covers inorganic fertilizers that fall outside the scope of other C05 subclasses (such as nitrogen, phosphate, or potassium-based fertilizers with specific compositions), including formulations and manufacturing processes for these residual fertilizer types. This subclass specifically encompasses fertilizers that generate carbon dioxide as a functional component or byproduct, such as urea-based products and certain mineral amendments that release CO₂ during application or storage. The classification addresses both standalone inorganic fertilizer compositions not adequately covered elsewhere and combined fertilizer products designed to provide agronomic benefits through CO₂ generation. Manufacturing methods, handling, and formulation techniques for these specialized inorganic fertilizers are also included within this subclass.

Scope Notes

Glossary: fertiliser (fertiliser material) natural or artificial substance containing the chemical elements that improve growth and productiveness of plants. inorganic compound inorganic compounds (taken from the glossary of terms for subclasses , and ) a compound devoid of a carbon atom and containing a non-metallic element or a compound containing a carbon atom, and satisfying one of the following criteria: The compound cannot have a carbon atom having direct bonding to another carbon atom, or the compound cannot have direct bonding between a carbon atom and a halogen or hydrogen atom, or the compound cannot have direct bonding between a carbon and a nitrogen atom by a single or double bond. The following are exceptions to the above and are to be considered as inorganic compounds: compounds consisting of only carbon atoms, (e.g. fullerenes), cyanogen, cyanogen halides, cyanamide, phosgene, thiophosgene, hydrocyanic acid, isocyanic acid, isothiocyanic acid, fulminic acid, unsubstituted carbamic acid, and salts of the previously mentioned acids and which contain the same limitations as to a carbon atom.
