SDCL § 38-19-28: Recommendation of grades of fertilizers for use in state--Publication of recommended lists.

The secretary of agriculture and natural resources may in his discretion hold public hearing open to all interested parties and with the aid of available and impartial data promulgate a list of grades of mixed fertilizers recommended as adapted to the agricultural needs of the state. Immediately after such hearing or as nearly as practicable thereafter it shall be the duty of the secretary with the cooperation of the agricultural experiment station and the extension service to give wide publicity to such list of adapted grades of mixed fertilizers so the consumers may profit by this information and avoid loss of time and money by the use of fertilizers not adapted to their soil needs.
