Compound Fertiliser

A manufactured, primarily chemically combined, fertiliser, which are probably the commonest type used on turfgrass surfaces.

According to the Fertilisers Regulations 1991 it can mean by blending as well.
It will include a minimum of two nutrients, for example, Nitrogen and Phosphorus.

Traditionally, especially prior to the later 1970s, this term also meant a complete fertiliser which supplied all three main nutrients of N P K and which could be produced from the physical mixing of fertilisers. Up until this period the supply of manufactured compound fertilisers was not as extensive as in more modern times.
