A liquid fertilizer made from fish trade residue is called fish emulsion . This is one of the most ecologically friendly fertilizing options for your plants. A familiar fish emulsion formula is made from the processing residue of menhaden, a small, bony fish from the Atlantic Ocean. Fish emulsion may also be created from other varieties of fishes, such as wild salmon.
Fish waste is cooked to take out the oils and liquids. The solid waste materials are removed and transformed into animal fodder and fish meal. The oil is removed and the liquid filtrate is further processed for liquid fertilizer creation.
The unrefined emulsion is basic, so phosphoric acid is put in to make it more acidic. This process produces an acidic reaction, which serves as a stabilizer for the fish suspension. This important step is vital for the shelf life of the liquid fertilizer.
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.
Although blends differ, fish emulsion liquid fertilizer typically contains about 4 parts N, 2 parts P and 2 parts K. These trace elements are minerals that crops can use.
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 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 straight to the foliage as foliar feed.
But take note, before using this liquid fertilizer, correctly mix it with water to dilute.
Fish emulsion heats up rapidly in storage, so it’s crucial that you keep this at room temperature. Also, remember to mix only a small amount with water as the diluted version can’t be stored any longer.
