How to distinguish the true and false of chemical fertilizer
Identify from the packaging: first, check the mark. Chemical fertilizer bags must be marked with product name, nutrient content, grade, trademark, net weight, standard code, factory name, factory address, production license number, etc. If the above signs are not or incomplete, it may be fake fertilizer or inferior fertilizer. The second is to check the sealing of the package. Special attention should be paid to chemical fertilizers with obvious opening marks on the sealing of the bags, which means that it is possible to adulterate.
Identification from the smell: the liquid with strong pungent ammonia smell is ammonia; the fine particle with obvious pungent ammonia smell is ammonium bicarbonate; the sour fine powder is heavy superphosphate; and the special fishy smell is lime nitrogen. If calcium superphosphate has a very pungent and strange sour taste, it means that waste sulfuric acid is likely to be used in the production process. This chemical fertilizer is very toxic and can easily damage or burn crops, especially the rice seedling pond.
If losses are caused by accidentally buying fake and shoddy agricultural materials, farmers can safeguard their legitimate rights and interests through consultation, complaint and prosecution in the people's court. (finishing)
