What are the different classifications of Fish Fertilizer?
There are generally three types of fish fertilizers on the market. Natural Organic fish emulsion (Bio-Agro), amended fish emulsion, and enzymatic fish fertilizer. How natural organic fish emulsion is made has already been described above. Amended fish emulsion is produced the same way, but it has more than 1% synthetic materials, usually urea, added. A good example of this is Atlas Fish Fertilizer, sold only in the USA and Canada. Enzymatic fish fertilizer usually has an N-P-K of somewhere around 2-5-3 (vs. 5-1-1 or 5-2-2 for fish emulsions). A good way to tell which means of manufacturing was used is by referring to the N-P-K balance. Anything other than a range between 5-2-2 to 4-1-1 means the fish fertilizer isn’t made from natural organic fish emulsion. The enzymatic method has fish scraps being placed in a stainless steel vat, and enzymes are added to cause it to deteriorate. Then the remaining stik water has the oil skimmed off, and is reduced down to a 40-50% solid solution. At
