The term "percentage" by symbol or word, when used on a fertilizer label shall represent only the amount of individual plant nutrients in relation to the total product by weight.

(Effective August 9, 1979)

Sec. 22-111j-3. Labels

Latest version.

(a) When requested by the Commissioner of Agriculture, each manufacturer or distributor shall furnish, with his application for registration, all proposed labels for fertilizer and any directions for the use of such fertilizer.

(c) Any fertilizer which contains a minimum of 0.03% of boron in water soluble form shall carry the word "warning" or "caution" which shall be conspicuously displayed on such label. Such label shall list the crop or crops for which said fertilizer shall be used and shall state that the use of such fertilizer on any non-recommended crop may cause serious injury to such crop or crops.

(d) Any fertilizer which contains a minimum of 0.001% molybdenum shall carry the word "warning" or "caution" which shall be conspicuously displayed on such label.

Sec. 22-111j-5. Investigational allowances

Latest version.

(a) A commercial fertilizer, or any individual element contained therein, shall be deemed deficient if the analysis of nutrient is below the guarantee by an amount exceeding the values in the schedule below. Such guaranteed analysis shall be conducted in accordance with the recommended Association of Official Analytical Chemists (A.O.A.C.) procedures for obtaining samples and sample preparation. Such procedures are described in Official Methods of Analysis of the Association of Official Analytical Chemists, 11th edition, 1970, and in succeeding issues of the Journal of the Association of Official Analytical Chemists. Replicate data shall be evaluated by following the instructions listed in the Journal of the Association of Official Analytical Chemists, vol. 59, no. 5, pg. 935, table 19, October 1966.

Guarantee Percent	Nitrogen Percent	Available Phosphoric Acid, Percent	Potash Percent
04	0.49	0.67	0.41
05	0.51	0.67	0.43
06	0.52	0.67	0.47
07	0.54	0.68	0.53
08	0.55	0.68	0.60
09	0.57	0.68	0.65
10	0.58	0.69	0.70
12	0.61	0.69	0.79

28	0.83	0.74	1.33
30	0.86	0.75	1.39
32	0.88	0.76	1.44

(b) Secondary and minor elements shall be deemed deficient if any element is below the guarantee by an amount exceeding the values in the table below. The maximum allowable deviation of the values listed in such tables shall be one unit (1%).

Element	Allowable Deficiency
Calcium	0.2 unit + 5% of guarantee
Magnesium	0.2 unit + 5% of guarantee
Sulfur	0.2 unit + 5% of guarantee
Boron	0.003 unit + 15% of guarantee
Cobalt	0.0001 unit + 30% of guarantee
Molybdenum	0.0001 unit + 30% of guarantee
Chlorine	0.005 unit + 10% of guarantee
Copper	0.005 unit + 10% of guarantee
Iron	0.005 unit + 10% of guarantee
Manganese	0.005 unit + 10% of guarantee
Sodium	0.005 unit + 10% of guarantee
Zinc	0.005 unit + 10% of guarantee

(c) Method of determining investigational allowances. A minimum of two (2) values shall be averaged in order to determine that the minimum guarantee has been met. If more than two (2) values are obtained, all significant values shall be averaged. Each value may be "rounded" to one decimal place for easy recording, but each value shall be carried to two (2) decimal places in order to apply such established averages to the preceding table. If the requisite guarantee is not listed in such table, the necessary appropriate value shall be calculated by interpolation.

(d) Sampling. Wherever applicable, all sampling equipment used and procedures employed shal be those adopted by the Association of Official Analytical Chemists.
