A label, in a readable and conspicuous form, shall appear on the face or display side of any soil amendment and shall consist of:
(1) Net weight;
(2) Brand name;
(3) Analysis, including any soil amending ingredient and other ingredients and the percentage of each. In lieu of a guarantee expressed as a percentage, a product that claims the presence of a microbe or microbes shall guarantee the microbe or microbes as follows:
(a) Minimum number of each claimed viable organism at the genus and species level in colony forming units (CFU), spores, or propagules per gram or milliliter (cm3);
(b) Expiration date; and
(c) Storage and handling instructions;
(4) Purpose of the product;
(5) Directions for application; and
(6) Name and address of the registrant.
The secretary of agriculture and natural resources may establish rules, pursuant to chapter 1-26, to allow labeling by volume rather than weight pursuant to subdivision (1) of this section.
