However, due to the nature of ammonium chloride and if it is not applied properly, it often causes some adverse effects on the soil and crops. Therefore, the application of ammonium chloride should pay attention to the following "four inappropriate." First, it should not be applied on acidic soils.

Third, it is not suitable for fertilizer and Putian fertilizer. When ammonium chloride is applied to the soil, it will produce a variety of high-concentration chloride solutions that, when severe, will affect seed germination and seedling growth. Fourth, should not be applied to bogey crops. Ammonium chloride contains a lot of chlorine, if applied to sweet potatoes, potatoes, sugar beets, grapes, melons and other starch and sugar crops, will reduce the starch and sugar content; for tobacco, will reduce the combustibility of tobacco, affect quality; It is also sensitive to chloride ions, and it is prone to poisoning and affecting quality.
