What are the uses of ammonium chloride? How to apply ammonium chloride well? Please also understand the netizens to help introduce Ammonium chloride belongs to moderate acid fertilizer, nitrogen content is about 25%, appearance is white or light yellow fine crystal or small particles, hygroscopicity is small, easy to dissolve in water, crops are easy to absorb and other characteristics, can be used as base fertilizer and topdressing for crops, but should not be used as seed fertilizer. Therefore, the application method and precautions of ammonium chloride are sorted out in detail below for netizens 'reference. Application method of ammonium chloride: 1. Ammonium chloride is used as base fertilizer: After ammonium chloride is applied as base fertilizer, it is best to water it in time to leach chloride ions from the fertilizer to the lower soil layer and reduce adverse effects on crops. Subtropical rainy areas with a small amount of base fertilizer can not be watered. 2. Ammonium chloride is used as topdressing: Ammonium chloride is most suitable for topdressing rice. It works better than ammonium sulfate with the same amount of nitrogen. But ammonium chloride as topdressing to master the principle of a small number of times. Ammonium chloride should not be used as seed fertilizer and seedling fertilizer: Because ammonium chloride in the soil will produce water-soluble chloride, affecting seed germination and seedling growth. IV. Application of ammonium chloride needs to be covered with soil: With ammonium chloride as base fertilizer to apply 10 cm deep, and cover soil, so beneficial to soil adsorption fertilizer, improve nitrogen utilization rate. ammonium chloride application precautions: Note 1. In dry and rainless areas, it is best not to apply ammonium chloride or use ammonium chloride as little as possible to prevent aggravation of soil salt damage. Note 2, ammonium chloride contains chlorine in 66.3%, chlorine brought into the soil is a necessary nutrient element for crops, but if excessive, it will have a certain impact on crops, so it is forbidden to apply ammonium chloride on chlorine-free crops, such as tobacco, tea tree, grape, potato, watermelon, sugar beet, etc., and control the use of ammonium chloride during the seedling stage of crops. Note that ammonium chloride should not be used as seed fertilizer, and ammonium chloride should not be used as seed dressing fertilizer, because there is a large amount of chloride ions near the seed that are harmful to the seed and will affect the germination of the seed. Note 4, ammonium chloride is a physiological acid fertilizer, should avoid mixing with alkaline fertilizer; ammonium chloride is generally used in neutral soil and alkaline soil, acid soil should be carefully applied, in the application of ammonium chloride conditions can be combined with organic fertilizer application. Note that ammonium chloride should not be continuously applied in large quantities on the same field, and should be combined with other nitrogen fertilizers. What's lime nitrogen?
