When ammonia water participates in chemical reactions, it is usually considered that the molecules participating in the reaction are NH₃·H₂0 molecules. The ammonia concentration of agricultural ammonia water is generally controlled within the range of 15% to 18% nitrogen content, and the carbonization measurement is better than 100%. Fertilization is simple, and there are many prescriptions, such as furrow application, surface application, application with irrigation water or spray application.
Since ammonia is lighter than water, care should be taken to avoid excessive accumulation in local areas and burn plants when irrigating. Ammonia can be used as base fertilizer or top dressing. The ammonia water concentration commonly used in my country is 15%, 17% and 20% ammonia. The concentration of foreign agricultural ammonia water is slightly higher, generally 25% ammonia (20% nitrogen) products. The reason why ammonia water fertilizer is so widely used.
This is because N element is one of the main fertilizer elements, and ammonium salt is the main form of ammoniated nitrogen fertilizer. Ammonia is toxic because ammonia has a pungent odor that affects the respiratory tract and other toxic reactions, which turn it into ammonia Nitrogen fertilizer is the main absorption method, turning waste into treasure. In addition, ammonia water can absorb carbon dioxide in the air and convert it into the salts needed by plants to promote the growth of plants.
