Q. What is fish emulsion?
A. Fish emulsion is an organic condensed liquid derived from fish solids and fresh fish remains. It retains many of the micro- and macro-nutrients present in live fish and, as such, is used as an all-purpose, low-dosage fertilizer for most types of plants. It is usually found in a 4-1-1 or 5-1-1 ratio of nitrogen to phosphorus to potassium. Because of its low nutrient composition, it can be used along with other fertilizers, if necessary.
