Fertilizers Regulations

15 The guaranteed analysis of a fertilizer or a supplement shall include

• (a) in respect of each fertilizer, the minimum amount of total nitrogen, available phosphoric acid and soluble potash expressed in per cent,

• (b) in respect of each mixed fertilizer, other than customer-formula fertilizers and fertilizers represented for daily feeding and not for further dilution, the minimum amount of total nitrogen, available phosphoric acid and soluble potash expressed in per cent in whole numbers only,

• (c) in respect of each fertilizer, the minimum amount of calcium, magnesium and sulphur expressed in per cent on the elemental basis,

• (d) in respect of each fertilizer, the amount of each lesser plant nutrient, other than calcium, magnesium and sulphur, expressed in per cent on the elemental basis,

• (e) in respect of each tobacco fertilizer, the minimum amount of nitrate nitrogen, ammoniacal nitrogen and organic nitrogen expressed in per cent,

• (f) in respect of each tobacco fertilizer, the minimum and maximum amounts of chloride expressed in per cent on the elemental basis,

• (g) in respect of each mixed fertilizer containing at least 25 per cent of the nitrogen contained therein in water-insoluble form of plant or animal origin or other source of slowly available nitrogen, the minimum amount of water-insoluble nitrogen expressed in per cent,

• (h) in respect of an untreated organic or inorganic phosphatic fertilizer, the minimum amount of total phosphoric acid expressed in per cent,

• (i) where applicable, in respect of each supplement to which the analysis refers,

  • (i) the minimum amount of the active ingredient expressed in per cent,

  • (ii) the genus and, where known, the species of the active microorganism, and

  • (iii) the minimum number of active viable cells per gram of product of the genus and, where known, the species of the active microorganism in the product,

• (j) in respect of each fertilizer containing a pesticide, the amount of the active ingredient of the pesticide expressed in per cent,

• (j.1) in respect of agricultural liming materials whose calcium and magnesium compounds are capable of neutralizing soil acidity,

  • (i) the minimum amount of calcium and magnesium expressed in per cent on the elemental basis,

  • (ii) the minimum neutralizing value expressed in per cent of the acid neutralizing capacity of calcium carbonate, and

  • (iii) the per cent passing through a sieve having openings that are square and are each 0.149 mm (100 mesh TYLER screen) and 1.68 mm (10 mesh TYLER screen) in width,

• (j.2) in respect of acidifying materials capable of increasing hydrogen ion concentration of a growing medium, the minimum acidifying value expressed in per cent of the basic neutralizing capacity of hydrochloric acid,

where such ingredients are intentionally incorporated in that fertilizer or represented to be contained therein, and

• (k) in respect of natural rock phosphate basic slag, a mixture of natural rock phosphate and basic slag, hoof and horn meal and bone meal, the per cent passing through a sieve having openings that are square and are each 0.149 mm (100 mesh TYLER screen) in width;

• (l) in respect of each fertilizer, the maximum amount, expressed in per cent of leather, hoof, horn, hair, wool waste, garbage or any similar organic material unless the fertilizer or its constituents have been treated in a manner to make the phosphorus available and the potash soluble; and

• (m) in respect of manure, compost, humus or leaf mould, the minimum amount of organic matter expressed in per cent and the maximum amount of moisture expressed in per cent.
