See shape and color such as urea is white or light yellow, granular, acicular or prismatic crystals; ammonium bicarbonate is white or other variegated powder or granular crystals, some manufacturers produce large particles of flat spherical ammonium bicarbonate Ammonium sulfate is white crystals; Ammonium chloride is white or light yellow crystals; Superphosphate is off-white or light-skin powder; Calcium magnesium phosphate fertilizer is grayish brown or dark green powder; Potassium sulfate is white crystals or powder; Potassium chloride is White or light red particles; monoammonium phosphate is off-white or dark gray particles; diammonium phosphate is white or light yellow particles.
The liquid smelling strong pungent ammonia is ammonia; the fine pungent ammonia odor is ammonium bicarbonate; the fine powder with sour taste is heavy superphosphate; and the lime with special odor is lime nitrogen. If superphosphate has a very pungent and sour taste, it is likely that waste sulfuric acid is used during the production process. This poor quality fertilizer is very toxic and can easily damage or burn the crop.
Add water to dissolve and discriminate 1 gram of chemical fertilizer. Add water to the vessel to shake it up completely. All dissolved is nitrogen fertilizer or potash fertilizer. Dissolve in water but residue is superphosphate. Dissolve in water without residue or residue is very little. Water soluble but with a large ammonia smell is ammonium bicarbonate.

The last thing to be reminded is that although some fertilizers are true, but nutrient content is very low, such as superphosphate, the effective phosphorus content is less than 8% (the minimum standard should be up to 12%), then it belongs to inferior fertilizer and has little effect on crops. In this case, some samples (about 500 grams) can be collected and sent to the relevant local agriculture, chemical or standard departments for identification.
