NOVELTY - A fertilizer composition comprises a graphene support and a fertilizer material. USE - Fertilizer composition e.g. co-granulated fertilizer composition is used as slow release fertilizer composition for providing micronutrients to plant and for fertilizing agricultural crops (all claimed). ADVANTAGE - The fertilizer composition improves impact strength and abrasion resistance of plants, thus has more resistance to physical degradation during transport and handling. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) method (M1) of providing micronutrients to a plant, which involves applying the fertilizer composition; (2) method (M2) of fertilizing plants, which involves preparing the fertilizer composition and applying the fertilizer composition to an agricultural crop, where the graphene support is coated with the fertilizer material; and (3) production of fertilizer composition, which involves providing graphene support structures containing several functional groups, providing the fertilizer material in a salt form such that the graphene support structures are at least partially coated with the fertilizer material, and heating the partially coated graphene support structures to form a coating of the fertilizer material on the graphene support structures.
