Where this section sits in the code
  1. KRS Chapter 250

As used in KRS 250.361 to 250.451, unless the context otherwise requires:

(1) "Fertilizer" means any substance containing one (1) or more recognized plant

nutrients which is used for its plant nutrient content and which is designed for use

or claimed to ha ve value in promoting plant growth, except unmanipulated animal

and vegetable manures, marl, lime, limestone, wood ashes and other products

exempted by regulation by the director.

(2) "Fertilizer material" means a fertilizer which either:

(a) Contains impo rtant quantities of no more than one (1) of the primary plant

nutrients: nitrogen (N), phosphorus (P) and potassium (K); or

(b) Has eighty-five percent (85%) or more of its plant nutrient content present in

the form of a single chemical compound; or

(c) Is derived from a plant or animal residue or by -product or natural material

deposit which has been processed in such a way that its content of plant

nutrients has not been materially changed except by purification and

concentration.

(3) "Mixed fertilizer" me ans a fertilizer containing any combination or mixture of

fertilizer materials.

(4) "Specialty fertilizer" means a fertilizer distributed for nonfarm use.

(5) "Bulk fertilizer" means a fertilizer distributed in a nonpackaged form.

(6) "Brand" means a term, design, or trademark used in connection with one (1) or

several grades of fertilizer but shall not include any numeral that is misleading or

confusing.

(7) "Guaranteed analysis" means, until the director prescribes the alternative form of

"guaranteed anal ysis" in accordance with the provisions of this subsection, the

minimum percentage of plant nutrients claimed in the following order and form:

Total nitrogen (N) ----- percent

Available phosphate (P205) ----- percent

Soluble potash (K20) ----- percent

For unacidulated mineral phosphatic material and basic slag, bone, tankage and

other organic phosphatic materials, the total phosphate or degree of fineness may

also be guaranteed. Guarantees for plant nutrients other than nitrogen, phosphor us

and potassium may be permitted or required by regulation by the director. The

guarantees for such other nutrients shall be expressed in the form of the element.

The source, e.g. oxides, salts, chelates, etc. of such other nutrients may be required

to be stated on the application for registration and may be included on the label.

Other beneficial substances or compounds, determinable by laboratory methods,

also may be guaranteed by permission and advice of the director. When any plant

nutrients or other s ubstances or compounds are guaranteed, they shall be subject to

inspection and analysis in accord with the methods and regulations prescribed by

the director. When the director finds, after public hearing following due notice, that

the requirement for expressing the guaranteed analysis of phosphorus and potassium

in elemental form would not impose an economic hardship on distributors and users

of fertilizer by reason of conflicting labeling requirements among the states, he may

require by regulation thereaf ter that the "guaranteed analysis" shall be in the

following form:

Total nitrogen (N) ----- percent

Available phosphorus (P) ----- percent

Soluble potassium (K) ----- percent

The effective date of the regulation shall be not less than six (6) months fo llowing

the issuance thereof, except that the equivalent of phosphorus and potassium may

also be shown in the form of available phosphate and soluble potash for a period of

two (2) years following the effective date of the regulation. After the effective d ate

of the regulation total nitrogen, available phosphorus, and soluble potassium shall

constitute the grade.

(8) "Grade" means the percentage of total nitrogen, available phosphorus or phosphate,

and soluble potassium or potash stated in whole numbers in the same terms, order,

and percentages as in the guaranteed analysis; except specialty fertilizers may be

guaranteed in fractional units of less than one percent (1%) of total nitrogen,

available phosphorus or phosphate, and soluble potassium or potash and fertilizer

materials, bone meal, manures, and similar materials may be guaranteed in

fractional units.

(9) "Official sample" means any sample of fertilizer taken by the director and

designated as "official" by the director.

(10) "Ton" means a net weight of two thousand (2,000) pounds avoirdupois.

(11) "Primary nutrient" means total nitrogen, available phosphate or phosphorus, and

soluble potash or potassium.

(12) "Percent" or "percentage" means the percentage by weight.

(13) "Person" means individual, partnership, association, firm, or corporation.

(14) "Distribute" means to import, consign, manufacture, produce, compound, mix, or

radio announcements used in promoting the sale of the fertilizer.

(19) "Investigational allowance" means an allowance for variations inherent in the

(20) "Manufacturer" means any person engaged in the business of p reparing, mixing, or

manufacturing fertilizers or the person whose name appears on the label as being

(21) "Manufacturing" means preparing, mixing, or combining fertilizer materials

(22) "Lot" means an identifiable quantity of fertilizer that can be sampled according to

or the amount delivered under a single invoice, and, in the case of bagged fertilizer,

not more than twenty-five (25) tons.

(23) "Blending" means physically mixing or combining two (2) or more fertilizer

materials including the mixing through the simultaneous application of two (2) or

more fertilizer materials by a blender or another person.

(24) "Blender" means any person who is engaged in the business of blending fertilizers.
