First, identify from the packaging: 1. Check the mark. According to relevant national regulations, chemical fertilizer packaging bags must be marked with the product name, nutrient content, grade, trademark, net weight, standard code, factory name, site, production license number, etc.; if the above-mentioned mark is not complete or incomplete, it may be false. Fertilizer or poor fertilizer. 2, check the bag seal. Special attention should be paid to chemical fertilizers that have obvious sealing and sealing marks on the bags. This fertilizer may be adulterated.
The second is to identify from the shape and color: 1, urea: white or light yellow, granular, acicular or prismatic crystals. 2, ammonium sulfate: white crystals. 3, Ammonium bicarbonate: White or other variegated powder or granular crystals, individual manufacturers produce large particles of flat spherical ammonium bicarbonate. 4, ammonium chloride: white or light yellow crystals. 5. Ammonium nitrate: White powder or white, light yellow ball city particles. 6, ammonia: For colorless or dark liquid. 7, lime nitrogen: grayish black powder. 8, superphosphate: gray or light skin powder. 9, heavy calcium phosphate: dark gray, gray particles or powder. 10, calcium magnesium phosphate: grayish brown or dark green powder. 11. Calcium, Magnesium, Phosphorus and Potassium: Grayish brown or dark green powder. 12. Phosphorite powder: Gray, brown or yellow fine rain powder. 13, Nitrophosphate: gray particles. 14, potassium sulfate; white crystals or powder. 15. Potassium chloride: white or light red particles. 16, monoammonium phosphate: gray or dark gray particles. 17. Diammonium phosphate: white or light yellow particles.
The third is to identify from the smell: the liquid with strong pungent ammonia taste is ammonia water; the fine particles with obvious pungent ammonia taste is ammonium bicarbonate. The fine powder with sour taste is heavy calcium phosphate, and the lime with special smell is lime nitrogen.
