A. Sections 8-77.1 through 8-77.18 of this subarticle shall be

known and may be cited as the "Oklahoma Fertilizer Act".

B. The purpose of the Oklahoma Fertilizer Act is to provide

assurances to the consumer that fertilizer products are properly

identified, and that the quality represented by the manufacturer is

accurate as well as for regulation of the storage, use, and

application of fertilizer to protect the consumer and the

environment.

C. The Legislature hereby occupies and preempts the entire

field of legislation in this state touching in any way the

regulation and enforcement of the registration, labeling, sale,

storage, transportation, distribution, notification of use, and

agricultural use of fertilizer to the complete exclusion of any

order, ordinance or regulation by any municipality or other

political subdivision of this state.

D. No political subdivision shall regulate the registration,

packaging, labeling, sale, storage, distribution, agricultural use

or application of fertilizer. No political subdivision shall adopt

or continue in effect local orders, ordinances, or regulations in

this field, except for those relating to nonagricultural use or

application or taxation relating to registration, packaging,

labeling, sale, storage, distribution, use or application of

fertilizers. Local legislation in violation of this section is void

and unenforceable.
