Fish emulsion is a liquid fertilizer made from fish residue. This is a liquid organic fertilizer that is good for plants and good for the environment. A common fish emulsion formula is made from the processing residue of menhaden, a small, bony fish from the Atlantic Ocean. Waste byproducts from other fishes, like wild salmon, can also be used to create fish emulsion fertilizers.

Fish waste is boiled to remove the oils and liquids. The solid wastes are removed and transformed into animal fodder and fish meal. The fish oil is taken off, and the liquid residue is cooked further to produce a thick suspension.

The unrefined emulsion is basic, so phosphoric acid is put in to make it more acidic. This process produces an acidic effect, which serves as a stabilizer for the fish emulsion. If not for this procedure, the mixture will rot and ferment. This is a specifically vital part of the liquid fertilizer manufacturing procedure.

Making liquid fertilizer from fish waste is a good alternative for farmers who live next to a sea port or a fish processing zone. It’s reasonably easy to create liquid fertilizer from fish processing waste materials.

There are many blends, but the classic fish emulsion liquid fertilizer comprises about 4 parts N, 2 parts P and 2 parts K. These trace elements are additional nutrients that plants require.

One of the advantages of using liquid fertilizer is the quick absorption of minerals by the crops. This formula can match the fast-release chemical fertilizers in terms of speed and effectiveness. What’s more, the fact that the processing residues of the fish industry are utilized for producing fish emulsion guarantees that this fertilizer is 100% environmentally sound.

If your crops belong to the seasonal or quick growing varieties, you can use this liquid fertilizer as a foliar spray to enhance leaf development and flowering.

But take note, before using this liquid fertilizer, correctly mix it with water to dilute.

While mixing fish emulsion with water is a part of the application procedure, the mixture cannot be kept in storage. As a result, it’s better to plan ahead and use only what you need so you can stock the concentrated suspension longer. Pure liquid emulsion must be kept at room temperature to prevent it from heating up.
