SCHEDULE 2METHODS OF ANALYSIS
PART I
4a.DETERMINATION OF THE TOTAL NITROGEN IN CALCIUM CYANAMIDE—IN THE ABSENCE OF NITRATE
EXPRESSION OF THE RESULT8
Express the result as the percentage of 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.
