These little fertilizer knowledge suggest that farmers should find out
Urea Urea is suitable for all kinds of soils and *** crops. It is suitable for application as base fertilizer and topdressing, but not as seed fertilizer.
Nitrogen, phosphorus and potassium compound fertilizers are suitable for base fertilizer and early topdressing.
Calcium-magnesium-phosphate fertilizers are weakly alkaline and can be used as base fertilizers, but they are generally not suitable for application as top dressing and are suitable for acidic soils.
Superphosphate is a weakly acidic fertilizer and can be used as a base fertilizer, seed fertilizer and top dressing. It is suitable for neutral or acidic soils. Generally, it should be used with organic fertilizers. When top dressing, use its filtrate and spray it outside the roots. Shi.
Ammonium nitrate is a weakly acidic fertilizer and can be used as top dressing, but cannot be used as base fertilizer or seed fertilizer. Early spring crops are not suitable for application, do not mix with organic fertilizers and retort. It is often used for dryland crops, but the effect is relatively poor when applied to paddy fields.
Ammonium chloride is a physiologically acidic fertilizer that can be used as a base fertilizer and top dressing, but cannot be used as a seed fertilizer. It is suitable for calcareous soil or partly acid soil, but not suitable for saline soil and tobacco, grapes, potatoes and other chlorine-free crops.
Nitrogen and potassium compound fertilizers should not be used as top dressing for crops that prefer potassium and avoid chlorine, and they are not suitable for application in paddy fields.
Potassium sulfate is a physiologically acidic fertilizer that can be used as a base fertilizer and top dressing. Potassium sulfate is suitable for all kinds of crops, especially those that avoid potassium chloride and potassium. It should be applied appropriately and concentratedly.
Potassium dihydrogen phosphate is currently mostly used for seed soaking and extra-root topdressing, and the effect is good.
Nitrogen and phosphorus compound fertilizers are suitable for use as base fertilizers. If they are used as top dressing, they should be applied early.
Potassium chloride is a physiologically acidic fertilizer that is suitable for use as a base fertilizer. If it is applied in acid soil, it should be used in conjunction with organic fertilizer or lime. Note that it is not suitable for saline-alkali soils, and it is not suitable for chlorine-free crops.

1. It is mainly used for waste water treatment for textile, printing, dyeing, paper-making, mining, ink, and so on.
2. It can be used for color removal treatment for high-colority waste water from dyestuffs plants. It is suitable to treat waste water with activated, acidic and disperse dyestuffs.
Application Method
1.The product shall be diluted with 10-40 times water and then dosed into the waste water directly. After being mixed for several minutes, it can be precipitated or air-floated to become clear water.
2. The pH value of the waste water should be adjusted to 6-10 for better result.
3. When the colority and CODcr are relatively high, it can be used with the help of polyaluminum chloride, but not mixed together. In this way, the treatment cost can be lower. Whether polyaluminum chloride is used earlier or afterwards depends on the flocculation test and the treatment process.
