(2). Each guarantee shall be expressed as a minimum guaranteed percentage by weight of the fertilizer.
ATCP 40.10 Note
Note: All of the materials identified in sub. (2), except cobalt and sodium, are plant nutrients. Cobalt and sodium are “enhancing elements." See ATCP 40.02 (7).

3. That a fertilizer contains an enhancing element other than cobalt or sodium, unless that enhancing element is guaranteed as a soil or plant additive ingredient under sub.
(10).
ATCP 40.10 Note
Note: A fertilizer that claims enhancing elements, other than cobalt and sodium, is considered a “fertilizer-additive combination." See ATCP 40.02 (9).
