Preface: Each State in the United States, Puerto Rico and Canada has its own fertilizer regulatory program. The Association of American Plant Food Control Officials (AAPFCO) strives to gain uniformity among each of these entities without compromising the needs of the consumers, protection of the environment or fair competition among the industry.
Membership: AAPFCO is an organization of fertilizer control officials from each state in the United States, from Canada and from Puerto Rico who are actively engaged in the administration of fertilizer laws and regulations; and, research workers employed by these governments who are engaged in any investigation concerning mixed fertilizers, fertilizer materials, their effect, and/or their component parts.
