Fish emulsion has played an important part in farm production, and with the results farmers have experienced, the use of fish emulsion is on the rise. It is an important ingredient in today’s farm fertilizer.

Our farms give our country what we need to live happy, healthy lives, not to mention the work that it provides. Today’s economy is struggling and it would be disastrous to have to rely on another country for our everyday sustenance. As long as our farmers are using fish emulsion for their farm fertilizer, our produce and grains will stay in our own back yards no “made in China” stamped on our tomatoes.

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.

A small amount of phosphoric acid is added to the fish emulsion to lower the pH. Lowering the pH makes the liquid fertilizer more acidic, which prevents it from decaying and fermenting into gas. Before phosphoric acid was added in the manufacturing process, containers of fish emulsion were known to burst from fermentation. Because the amount of added phosphoric acid is so small (less than one percent by weight), the product is still considered organic.
