§ 73.6. Slowly available plant nutrients.
(a) No fertilizer label may bear a statement that implies the presence of a slowly available plant nutrient unless the nutrient is identified on the label.
(b) If a fertilizer label implies that nitrogen is slowly available, for example, organic nitrogen, the guaranteed analysis shall indicate the percentage of water-insoluble nitrogen in the material.
(c) If the label states the amount of organic nitrogen present in a phrase such as 25% of the nitrogen from ureaformaldehyde (Ureaform), the water-insoluble nitrogen guarantee may be not less than 60% of the nitrogen so designated.
(d) If the water-insoluble nitrogen is less than 15% of the total nitrogen, the label may not bear designations such as organic, ureaform or similar terms.
(e) The phrases coated-slow release fertilizer and coated-slow releast are acceptable descriptive terms for products for which a testing program has substantiated the claim. Water-insoluble nitrogen shall be guaranteed at 15% of the total nitrogen level for slow release materials.
(f) The Association of Official Analytical Chemists Test Method as prescribed in Methods of Analysis shall be used to substantiate the presence of slow release materials. It is permissible to eliminate grinding during sample preparation.
The provisions of this § 73.6 adopted July 28, 1972, effective July 29, 1972, 2 Pa.B. 1435; amended February 9, 1979, effective February 10, 1979, 9 Pa.B. 498. Immediately preceding text appears at serial page (6734).
§ 73.7. Percentage.
The term percentages, by symbol or word if used on a fertilizer label, shall be deemed to represent only the amount of individual plant nutrients or other factors in relation to the total product by weight.
§ 73.8. Investigational allowances or tolerances.
(a) A commercial fertilizer shall be deemed deficient if the analysis of any nutrient is below the guarantee by an amount exceeding the values in the following schedule:

Notes of Decisions
It was not necessary for the Department to establish where a particular fertilizer deficiency actually occurred but only to establish by substantial evidence that the fertilizer manufactured was deficient in its guaranteed nutrient components. Willard Agri-Service, Inc. v. Department of Agriculture, 554 A.2d 596 (Pa. Cmwlth. 1989).
The procedures adopted by the Association of Official Analytical Chemists (AOAC) and utilized by the Department for obtaining samples, sample preparation and analysis were adequate. Willard Agri-Service, Inc. v. Department of Agriculture, 554 A.2d 596 (Pa. Cmwlth. 1989).
