Upon filing with the State Board of Agriculture and Industries of an application by any nonprofit association of wheat, corn, grain sorghum, and oats producers, the said board shall within 30 days thereafter meet and consider the application. If it is shown by the applicant to the satisfaction of the board that the applicant is fairly and substantially representative of the wheat, corn, grain sorghum, and oats producers of this state, and shall otherwise find and determine that such application and the program proposed therein are in conformity with the provisions and purposes of this article, then, and in such an event, the board shall certify such association as the duly delegated and authorized group or organization and shall likewise certify that such organization is duly authorized to conduct among the wheat, corn, grain sorghum, and oat producers of this state a referendum for the purpose set forth in its application which shall be consistent with the purposes of this article. In the event there is more than one pending application at any time, the board must decide between the pending applications based on the program proposed, the number and geographical distribution of wheat, corn, grain sorghum, and oat producer members in the applicant organization, the size, stability, potential effectiveness and fiscal soundness of the applicant organization and any organizations with which it is affiliated, the existence and effectiveness of affiliated county organizations in the applicant organization and its affiliates, and the sentiment of wheat, corn, grain sorghum, and oat producers as ascertained by petitions, hearings, and otherwise as may be determined by the board. No application shall be considered if an organization holds currently valid certification.
