Remark:1, sing nutrient is not less than 4.0%, the difference between inspection and nominal value is not more than 1.5%.
2, Index .Fused calcium magnesium phosphate should be signed as citric acid soluble phosphorus on the packing, the percent of water soluble phosphorus/active phosphorus is unnecessary; for N/K fertilizer, the percent of water soluble phosphorus/active phosphorus is unnecessary too.
3, If the assay of chlorine ions is more than 30%, the packing should be sign with the symbol of "Chlorine", the test of Chlorine ion is unnecessary, or we have to test its assay.
