Fish emulsion is a liquid fertilizer made from fish residue. This is a liquid organic fertilizer that is great for plants and good for the ecosystem. A common fish emulsion formulation is made from the processing waste of menhaden, a small, bony fish from the Atlantic Ocean. Waste products from other fishes, like wild salmon, can also be utilized to make fish emulsion fertilizers.
Fish waste is cooked to take out the oils and liquids. The solid waste materials are removed and transformed into animal feed and fish meal. The fish oil is taken off, and the liquid residue is boiled further to generate a thick suspension.
The unprocessed emulsion is basic, so phosphoric acid is put in to make it more acidic. The acidic nature of the ensuing end product prevents the emulsion from fermenting. This important step is crucial for the shelf life of the liquid fertilizer.
Making liquid fertilizer from fish residue is a good choice for farmers who live near a sea port or a fish processing district. It is more or less easy to create liquid fertilizer from fish processing wastes.
There are many formulas, but the typical fish emulsion liquid fertilizer comprises about four to five percent nitrogen (N), two percent phosphorus (P), two percent potassium (K), and trace elements. These trace elements are micronutrients that plants can use.
Because the suspension is liquid, it can be absorbed quickly by crops. This formulation can equal the fast-release chemical fertilizers in terms of speed and efficiency. What’s more, the fact that the processing waste materials of the fish industry are used for creating fish emulsion guarantees that this fertilizer is 100% environmentally sound.
If your gardening style involves transplants and seedlings, a quick acting organic fertilizer such as fish emulsion may be ideal for you. You have the option to apply this fertilizer directly to the foliage as foliar feed.
But take note, prior to using this liquid fertilizer, appropriately mix it with water to dilute.
While mixing fish emulsion with water is a part of the application process, the mixture can’t be stored. Therefore, it’s better to plan ahead and use only what you need so you can store the thick suspension longer. Undiluted liquid emulsion must be kept at room temperature to prevent it from heating up.
