On Saturday, September 9, 2023, AOAC INTERNATIONAL will turn 139 years old. The Association of Agricultural Chemists officially became an organization on September 9, 1884, during the annual American Association for the Advancement of Science conference in Philadelphia, PA.

The objectives presented in the first Constitution of the Association were, “to secure, as far as possible, uniformity in legislation with regard to the regulations of the sale of commercial fertilizers in the different states and uniformity and accuracy in the methods and results of fertilizer analysis.”

The first three standing committees were established for phosphoric acid, potash, and nitrogen. Their duties were, “to test methods, to distribute samples to members of the Association and others who may signify their desire to participate in the work, and to present a written report at each annual meeting embodying the progress made during the year in analytical methods bearing on their respective topics and the results done under their direction.”
