A granular fertiliser including gelatine (for controlling the breakdown of the fertiliser) may comprise individual granules, each granule having an outer coating of gelatine. The fertiliser may include one or more additives (e.g. a weed-killer) and may be provided with a supplementary outer coating (e.g. of bentonite) and if required a hardening agent (e.g. gypsum) and an outer finishing layer (e.g. talc or vermiculite). |
