Ammonium chloride fertilizer is suitable for crops such as wheat, rice, corn, rapeseed, etc. It has the effect of enhancing fiber toughness and tensile strength, and improving quality, especially for cotton and hemp crops. However, due to the nature of ammonium chloride and its improper application, it often brings some adverse effects to the soil and crops.
Experts suggest that farmers should pay attention to the following points when purchasing, using, and storing ammonium chloride products:
1、 Purchase
When purchasing, the first thing to judge from the appearance is that pure ammonium chloride is a white or slightly yellow square or octahedral small crystal, with a salty and cool taste. It is heated, sublimated or decomposed, and looks very similar to table salt on the surface, easily soluble in water. In addition, when purchasing, products with large scale, good quality and reputation, and standardized packaging and labeling should also be selected.
2、 Using
The application methods of agricultural ammonium chloride mainly include the following:
1. Used as a base fertilizer. After applying ammonium chloride as a base fertilizer, it should be watered in a timely manner to leach the chloride ions from the fertilizer to the lower soil layer and reduce the adverse effects on crops.
2. Used as topdressing. When used as top dressing, the dosage per acre is generally around 10-17.5 kilograms, but the principle of small amounts and multiple times should be followed.
3. Not suitable for use as seed fertilizer and seedling fertilizer. Because ammonium chloride generates water-soluble chlorides in the soil, it affects seed germination and seedling growth.
4. It cannot be used for chlorine free crops such as tobacco, sugarcane, sugar beets, tea trees, potatoes, etc. Crops such as watermelon and grapes are also not easy to use for a long time.
5. It cannot be used on saline alkali soil with unfavorable drainage to prevent aggravation of soil salt damage.
6. Ammonium chloride is suitable for paddy fields, but not for arid and rainy areas.
3、 Storage and transportation
Agricultural ammonium chloride should be kept dry during storage and transportation, avoiding rain, moisture, direct sunlight, and being stored together with alkaline and acidic substances.
