Fertilizers are necessary for crop production, but not all fertilizers can be used. Some fertilizers used in crops not only do not increase the income, but also cause pollution and affect the health of consumers. Experts reminded that the following fertilizers should be used cautiously on crops.
1. Organic fertilizer (waste fertilizer) made from organic raw materials such as municipal, hospital, industrial waste, and harmful sludge.
2. Unfertilized human excrement.
3. Unsoiled cake fat.
4. Superphosphate or other phosphate fertilizer (waste phosphoric acid fertilizer) produced from spent acid.
5. Foliar fertilizers containing hormones or hormones.
6. Chlorine-containing fertilizers (ammonium chloride, potassium chloride, chlorine-containing compound fertilizers) are prohibited from being used on chlorine-repellent crops.
7. Fertilizers containing nitrate nitrogen (including ammonium nitrate, potassium nitrate compound fertilizer and nitrate-containing compound fertilizer) are prohibited from being used on vegetables.
