The sample of the fertilizer is heated or burned, and the true and false of the fertilizer can be further identified from the color of the flame, the melting condition, the smell of the smoke, and the residue.
Nitrogen fertilizer: ammonium bicarbonate, direct decomposition, a large amount of white smoke, strong ammonia smell, no residue; ammonium chloride, direct decomposition or sublimation, a large amount of white smoke, strong ammonia and sour taste, no residue; urea It can melt quickly, emit white smoke, burn in charcoal fire, or take a piece of glass to contact white smoke. It can be seen with a layer of white crystal on the glass sheet; ammonium nitrate, does not burn, melts and appears boiled, emerges Smoke with ammonia smell; calcium nitrate, melting and burning, emitting light, leaving white lime.
Phosphate fertilizer: superphosphate, calcium magnesium phosphate, phosphate rock powder, etc. have no change on red charcoal; bone powder quickly turns black on red charcoal, releasing burnt smell.
Potassium fertilizer: potassium sulfate, potassium chloride, potassium magnesium sulfate, etc. have no change on the red charcoal, making a squeaking sound.
Compound fertilizer: The combustion of compound fertilizer is closely related to its constituent materials. When there is ammonia nitrogen or amido nitrogen in the raw material, it will emit strong ammonia smell and a large amount of residue; ammonium phosphate fertilizer can melt on red charcoal. Smoke and ammonia smell.
Boron fertilizer: On red charcoal, it will become dry and will not go out.
