1, urea and ammonium bicarbonate mixed. Fertilizer bag is loaded with urea, below the installed ammonium bicarbonate. It is characterized by the above urea hand pressure or pushing flow performance, the following does not flow, or even agglomerate, and can smell the pungent ammonia smell.
2, urea and ammonium nitrate Kun installed. The urea granules are larger, translucent, loose, non-reflective and damp, while the ammonium nitrate particles are smaller, the surface is shiny, and there is a clear sense of light and humidity.
Second, phosphate fertilizer. The counterfeit calcium superphosphate in the market mainly includes phosphogypsum, waste cement slag, etc. The identification method is:
1. Appearance: Calcium superphosphate is dark gray or white gray, light gray ash granules, sour taste; Phosphogypsum grayish white hexagonal granular crystal or crystalline powder, no sour taste; waste cement clinker is gray powder granular, dull, No sour taste, there are more hard particles.
2, feel: superphosphate texture, feel the hair but not frivolous; phosphogypsum light texture, feel hair, dry texture of waste cement than heavy calcium phosphate, feel not greasy, no cotton, not dry , there is a hard cement residue.
3, water-soluble. Superphosphate is partially soluble in water. If it is found in the identification that there are obvious impurities such as soil blocks, stones, and coal particles in the superphosphate, it is inferior superphosphate. If it is found that the acidity is too rich and the moisture is high, it is unqualified and not ripened. Calcium phosphate.
