5.2.2 Guarantees or claims for the above-listed plant nutrients are the only ones which will be accepted except that fertilizer guarantees may include other nutrients, recognized by AAPFCO. Proposed labels and directions for use of the fertilizer must be furnished with the application for registration upon request.

5.3 Slowly Released Plant Nutrients

5.3.1 No fertilizer label shall bear a statement that connotes or implies that certain plant nutrients contained in a fertilizer are released slowly over a period of time, unless the slow release components are identified and guaranteed at a level of at least 15% of the total guarantee for that nutrient(s).
