Fish meal: is made from dried fish waste. Oils that become rancid are removed, preservatives are added and the material is spray dried. The nutrient analysis of fish meal is around  N : P : K  =  10 - 12 : 6 : 2 making it a good choice to use with leafy plants.

The next 2 fish fertilizers have sulphuric and phosphoric acids added to stabilise the material. This makes up some of the fertilizer value - probably less than 1% P in Fish Emulsion.

Fish Emulsion: made from gutted fish waste which is dried to kill micro-organisms.

Nutrient analysis is around  N : P : K  =  5 : 2 : 2  It is readily soluble and used for folia spraying. This is especially useful in the colder earlier months when manures and slow release organic fertilizers may be breaking down too slowly.
