The commissioner shall accept guarantees only for the additional secondary and micro plant nutrients listed in this subpart. These additional plant nutrients in a particular fertilizer may be guaranteed if they meet the following minimum content requirements:
Plant Nutrient | Minimum Percent Allowed |
Calcium (Ca) | 1.00 |
Magnesium (Mg) | 0.50 |
Sulfur (S) | 1.00 |
Boron (B) | 0.02 |
Chlorine (Cl) | 0.10 |
Cobalt (Co) | 0.0005 |

Sodium (Na) | 0.10 |
Zinc (Zn) | 0.05 |
If any of the plant nutrients in subpart 2 are guaranteed, the procedures in items A to F must be followed for labels and labeling.
If the minimum requirement stated in subpart 2 is not met for a particular plant nutrient, labels and labeling for the fertilizer may not contain any statement regarding that particular plant nutrient.
When a plant nutrient guarantee is broken down into the component forms, the percentage for each component must be shown before the name of the form. Descriptive terms may be used to identify both the total nutrient and its components. Zero guarantees are not acceptable as noted in part 1510.0413, however, they are allowed in the nutrient breakdown guarantees.
Total Nitrogen (N) | ____% |
____% Ammoniacal Nitrogen | |
____% Nitrate Nitrogen | |
Magnesium (Mg) | ____% |
____% Water Soluble Magnesium (Mg) | |
Sulfur (S) | ____% |
____% Free Sulfur (S) | |
____% Combined Sulfur (S) | |
Iron (Fe) | ____% |
____% Chelated Iron (Fe) |
Plant nutrients, when mentioned in any form or manner on any label or labeling, must be listed and guaranteed.
Additional information that is not listed in subparts 1, item C; 2; and 5 may not appear in the guaranteed analysis statement, but may appear on the label if placed below and separate from the guaranteed analysis statement.
