Organic growers are more careful about what and where their liquid organic fertilizers come from. Hence, this article discusses how liquid fish emulsions are made. First of, they are mostly made from the Menhaden fish which is not considered a human food source. However this fish is used for making oil and animal feeds. The waste from the production of this fish into oil or animal feed is the ingredient used for making liquid fish fertilizers.

The process of making liquid fertilizer starts with cooking the fish and pressing out the oils and liquids. The solids are made into fishmeal, animal feed, and other products. The oil, which is literally worth its weight in gold, is skimmed off. The liquid is boiled down until it thickens, making fish emulsion.

To prevent decay and gas fermentation, a minute quantity of phosphoric acid is mixed with the fish emulsion. However, this mixture is still considered organic since the preservative is below 1%.

Standard composition of organic fish emulsion fertilizers is about 5% Nitrogen, 2% Phosphorous, and 2% Potassium. It also contains micronutrients that are vital for promoting plant growth.

Adventurous gardeners make their own liquid fertilizer from fish. It’s a smelly, messy process, but it could be economical for gardeners with a ready supply of fish waste.

Liquid organic fish emulsions are an exception to other organic fertilizers because they release nutrients to the plant immediately. Hence, liquid fish emulsions are used for transplanting seedlings because it makes them more viable. To use as fertilizer, the liquid fish emulsion is diluted in water and sprayed on plants or used to water the soil.

Instructions must be followed in using fish emulsions as fertilizers because over-application can burn the roots of the plant. And be prepared for the strong odor but it wanes in a day or so. Since it is organic, the fertilizer must be used at once it has been diluted and it cannot be exposed to heat.

Production of liquid fish emulsions fertilizers is environmentally sound from start to finish. Only fish parts that are unused or are considered as waste by fish and feed processing companies are used. Thus, the use of fish emulsions organic fertilizers thus decrease toxins in our food and helps make zero waste possible.
