  • (12)"Fertilizer material" means a fertilizer that contains:
    • (a)quantities of no more than one of the primary plant nutrients, nitrogen (N), phosphate (P2O5), Potash (K2O);
    • (b)85% plant nutrients in the form of a single chemical compound; or
    • (c)plant or animal residues or by-products, or a natural material deposit that is processed so that its primary plant nutrients have not been materially changed, except through purification and concentration.
  • (13)"Grade" means the percentage of total nitrogen, available phosphate and soluble potash stated in the same terms, order, and percentages as in the guaranteed analysis.
  • (14)
    • (a)"Guaranteed analysis" means the minimum percentage by weight of plant nutrients claimed in the following order and form:
      • Total Nitrogen (N) ____ percent
      • Available Phosphate (P2O5) ____ percent
      • Soluble Potash (K2O) ____ percent
    • (b)For unacidulated mineral phosphatic material and basic slag, bone, tankage, and other organic phosphate or degree of fineness may also be guaranteed.
    • (c)
      • (i)Guarantees for plant nutrients other than nitrogen, phosphorus, and potassium may be permitted or required by rule of the department.
