The following is an example of an acceptable breakdown of nitrogen for a fish emulsion fertilizer:
Total Nitrogen (N) | 5% |
0.0% Nitrate Nitrogen | |
0.0% Urea Nitrogen | |
0.5% Ammoniacal Nitrogen | |
0.5% Water Insoluble Nitrogen | |
4.0% Other Water Soluble Nitrogen |
In the example given above, water insoluble nitrogen is guaranteed but no claims or statements, such as slow acting or slow release, can be used since it is less than 15 percent of the total nitrogen.
