(1)  Slowly available nutrients.

(a)  No fertilizer label shall bear a statement that connotes or infers the presence of a slowly available plant nutrient, unless the nutrient or nutrients are identified.

(b)  When a fertilizer label infers or connotes that the nitrogen is slowly available through use of organic, organic nitrogen, ureaform, long lasting or similar terms, the guar-anteed analysis must indicate the percentage of water insoluble nitrogen in the material.

(c)  To supplement (b)  , it should be established that if a label states the amount of organic nitrogen present in a phrase, such as "25% or the nitrogen from ureaformaldehyde (ureaform)  ," then the water insoluble nitrogen guarantee must not be less than 60% of the nitrogen so designated.

     Example:   10-6-4 Rose Food

                         25% of Nitrogen if Organic

10(Total N Guaranteed)  x .25 (% N Claimed as Organic)  x .60= 1.5% WIN

(d)  When the water insoluble nitrogen is less than 15% of the total nitrogen, the label shall bear no references to any designations, such as stated in (b)  .

(e)  The term "Coated-Slow Release Fertilizer", or "Coated-Slow Release" may be accepted as descriptive of products.

(f)  Further, the above phrases (e)  be allowed for any products that can show a testing program substantiating the claim. (Testing under guidance of experiment station personnel, or a recognized reputable researcher, etc.)  . Water insoluble nitrogen must be guaranteed at the 15% of total nitrogen level as in organic materials.

(g)  Products claiming to be "Coated" or "Slow Release" will be tested without grinding by the most appropriate procedure available to substantiate the claim.
