Description
C05G covers fertilizer compositions that combine multiple fertilizer types classified under different C05 subclasses, as well as fertilizer formulations with non-nutritive additives such as binders, anti-caking agents, colorants, or soil conditioners. This subclass also encompasses fertilizers defined primarily by their physical form (granules, pellets, coated products, suspensions, gels) rather than their chemical composition alone. The classification captures complex, multi-component fertilizer products that do not fit neatly into single-fertilizer-type categories defined by other C05 subclasses.
