Crumb Fertiliser

A fine gritty and ground material, which may be organic, such as Hoof and Horn, or Bonemeal; or inorganic such as a manufactured fertiliser. A typical size for an organic crumb fertiliser is 3mm to 4mm, going down to dust within the material. Crumb fertilisers can be added to a surface without the need for a carrier to bulk up the product, unlike powdered fertilisers. This term may also be referred to as Fertiliser Crumb.
