Section 2:69-1.2 - Investigational allowances for primary nutrients

(a) A commercial fertilizer shall be deemed to be deficient if the analysis of any nutrient is below the guarantee by an amount exceeding the values in the following schedule, or if the overall Index Value of the fertilizer is below 98 percent. When the deviation from the guarantee is not in excess of the amounts shown, the fertilizer shall be considered as substantially meeting its guarantee. If the deviation is greater than the value shown, but less than twice the value shown, a warning shall be issued. If the deviation exceeds twice the value shown, the fertilizer shall be considered seriously deficient and subject to a penalty. When the Index Value falls between 98 percent and 95 percent a warning shall be issued. If the Index Value falls below 95 percent, the fertilizer shall be considered seriously deficient and subject to a penalty.

For guarantees not listed, calculate the appropriate value by interpolation.

For these investigational allowances to be applicable, the recommended Association of Official Analytical Chemists' procedures for obtaining samples, sample preparation and analysis must be used.

(b) For WIN (Water Insoluble Nitrogen), deviations of ten per cent and 20 per cent respectively shall be used to determine whether a warning or penalty is appropriate.

Example:
3% WIN
Pass	3.0	-	2.7
Warn	2.69	-	2.4
Penalty below			2.4
