The result of the analysis must be expressed as the percentage of total nitrogen (N) contained in the fertiliser as received for analysis.

Variant (a): N% = (50 − A) × 0.7

Variant (b): N% = (50 − A) × 0.7

Variant (c): N% = (35 − A) × 0.875

Where A = millilitres of sodium or potassium hydroxide used for the titration.
