“Agricultural liming materials” are agricultural minerals composed of calcium or magnesium compounds, or both, which are capable of neutralizing soil acidity and which are distributed in this state for that purpose.

“Agricultural mineral” means any substance with nitrogen (N), available phosphoric acid (P2O5), and soluble potash (K2O), singly or in combination, in amounts less than 5 percent which is distributed for farm use, or any substance only containing recognized essential secondary nutrients or micronutrients in amounts equal or greater than minimum amounts specified by the director, by regulation, and distributed in this state as a source of these nutrients for the purpose of promoting plant growth. It shall include gypsum, liming materials, manure, wood fly ash, sewage sludge not qualifying as commercial fertilizer, and captured dilute solutions.

“Ammonium nitrate” means solid ammonium nitrate that is chiefly the ammonium salt of nitric acid, contains not less than 33 percent of nitrogen, one-half of which is in the ammonium form and one-half of which is in the nitrate form, and is produced, imported, stored, offered for sale, sold, offered for distribution, received, or intended for use as a plant nutrient.

“Beneficial substance” means any substance or compound, other than primary plant nutrients, secondary plant nutrients, and micronutrients, and excluding pesticides, that can be demonstrated by scientific research to be beneficial to one or more species of plants, soil, or media. A beneficial substance includes, but is not limited to, plant biostimulants.

“Biochar” means materials derived from thermochemical conversion of biomass in an oxygen-limited environment containing at least 60 percent carbon.

“Biotics” means all materials for which claims are made relating to organisms, enzymes, or organism by-products.

“Board” means the Fertilizer Inspection Advisory Board.

“Brand” means any term, design, or trademark used in connection with a fertilizing material product.

“Bulk material” means fertilizing materials distributed in nonpackaged form or in a container containing more than 50 kilograms or 110 pounds.

“Business location” means any place where fertilizing materials are sold or stored for later sale, except storage of package materials on premises operated exclusively as a public warehouse.

“Captured dilute solutions” means solutions that contain low levels of plant nutrients as a result of equipment rinsing and runoff.

“Chelates” means compounds, usually organic, which can combine with a metal ion and form a ring structure between a portion of the chelating agent molecule and the metal.

“Chelated plant nutrients” means compounds of metallic secondary nutrients and micronutrients with organic chelating agents which have the property of being available under pH conditions in which the nutrients normally form insoluble compounds.

“Commercial fertilizer” means any substance which contains 5 percent or more of nitrogen (N), available phosphoric acid (P2O5), or soluble potash (K2O), singly or collectively, which is distributed in this state for promoting or stimulating plant growth. “Commercial fertilizer” includes both agricultural and specialty fertilizers. “Specialty fertilizers” may contain less than 5 percent nitrogen (N), available phosphoric acid (P2O5), or soluble potash (K2O), singly or collectively.

“Common carrier” means a company licensed with the Public Utilities Commission that hauls for hire.

“Complex” means bonding which includes both of the following:

“Compost” means a biologically stable material derived from the composting process.

“Composting” means the biological decomposition of organic matter which inhibits pathogens, viable weed seeds, and odors. “Composting” may be accomplished by mixing and piling in a way as to promote aerobic or anaerobic decay, or both.

“Derivation statement” means the sources of all guaranteed primary nutrients or secondary nutrients, or both, and micronutrients.

“Discontinued manufacturing” means a beneficial substance, packaged agricultural mineral, organic input material, and specialty fertilizer that is no longer manufactured, but is still offered for sale.
