The Fertilizing Materials Inspection Program is an industry-funded program that ensures consumers receive fertilizing materials that are safe and effective and meet the quality and quantity guaranteed by the manufacturer. Inspectors and investigators located throughout the state conduct routine sampling and inspections; respond to consumer complaints; and enforce the laws and regulations that govern the manufacturing and distribution of fertilizing materials. Registration Specialists carefully review product labels for misleading claims and compliance with existing labeling requirements. (Fertilizing Materials Licensing, Registration & Labeling Guide)
