## Chapter 7-15-02 — Micronutrient Guaranteed Analysis

### § 7-15-02-01. Accepted micronutrient minimum concentrations.

Micronutrients when mentioned in any form or manner shall be registered and guaranteed.
Guarantees shall be made on the elemental basis; however, the source of the micronutrient must be
specified. For example, a micronutrient that is a mixture of EDTA and citric acid bound micronutrient
must specify the percentage of total micronutrient in each form. An iron EDDHA micronutrient must
specify the percentage of total iron in ortho-ortho-EDDHA and ortho-para-EDDHA. Except guarantees
for those water soluble nutrients labeled for ready-to-use foliar fertilizers, read-to-use specialty liquid
fertilizers, hydroponic or continuous liquid feed programs and guarantees for potting, garden, and lawn
soils, the minimum percentages which will be accepted for registration are as follows:
Element Minimum Conce., %
Calcium (Ca) 1.0000
Magnesium (Mg) 0.5000
Sulfur (S) 1.0000
Boron (B) 0.0200
Chlorine (Cl) 0.1000
Cobalt (Co) 0.0005
Copper (Cu) 0.0500
Iron (Fe) 0.1000
Manganese (Mn) 0.0500
Molybdenum (Mo) 0.0005
Nickel (Ni) 0.0010
Sodium (Na) 0.1000
Zinc (Zn) 0.0500

### § 7-15-02-02. Warning statements.

A warning or caution statement may be required for any product that contains a micronutrient in
water soluble form when there is evidence that the micronutrient in excess of a certain percentage or
concentration may be harmful to certain crops or human health, or where there are unusual
environmental conditions.
