Illinois Statutes Chapter 505. Agriculture § 120/20. Labeling

(a) On and after July 1, 1992, the following information shall appear on the face or display side in a readable and conspicuous form on every soil amendment product container or shall accompany each bulk order of a soil amendment product distributed in this State and shall be considered the label:

(b) The Director may require proof of claims made or usefulness or value of any soil amendment product. The Director may rely on experimental data, evaluations, or advice from sources such as the Agricultural Experiment Station and other professionally trained scientists for the required proof.

(c) No soil amending ingredient may be listed or guaranteed on the label without the permission of the Director. The Director shall allow ingredients to be listed if satisfactory proof of value and usefulness is provided that substantiates the usefulness and value of the ingredient and supports the claims made. When a soil amending ingredient is allowed to be listed or guaranteed, it must be determinable by laboratory methods and is subject to inspection and official sample analysis.

(d) The Director shall require the listing on the label of all substances included as other ingredients in each soil amendment product.

(e) The Director may allow labeling by volume rather than by weight.

(f) If the Director finds that a registered soil amendment product contains plant nutrient ingredients, regardless of amount, he or she may require the label to so state.
