Storage and storage of chemical fertilizers in winter and spring
Every winter farmers store fertilizers left in the year or purchased for the next spring. Some people do not understand the nature of chemical fertilizers. They neglect scientific management and stack them at random. This not only reduces fertilizer efficiency, but also causes danger. All kinds of fertilizers have different characteristics, some acidic or alkaline, some corrosive or toxic, some easily hygroscopic agglomeration, some volatile and lost, there are flammable and explosive. Especially after entering the spring, the warehouse will increase moderately. According to the different characteristics of various fertilizers, proper storage methods must be adopted to avoid deterioration or reduce fertilizer efficiency. Different kinds of chemical fertilizers should be put in a single storehouse in the warehouse, placed on a label, marked with the name and chemical composition, must not be mixed and stacked. Ammonium sulphate, ammonium hydrogen nitrate, ammonium chloride, and ammonia, etc., in the case of ammonium nitrogen fertilizer, when it is met with basic fertilizers such as ash, lime, and lime nitrogen, it is likely to cause nitrogen volatilization and reduce fertilizer efficiency; nitrate-nitrogen fertilizer such as ammonium nitrate and sodium nitrate, etc. The mixing of superphosphate causes the fertilizer to deliquesce, causing the nitrate nitrogen to gradually decompose and become run off by the gas, causing undue loss. The chemical fertilizer should be stored in a dry place in the warehouse, waterproof and moisture-proof. Fertilizers are generally easily soluble in water, and are prone to agglomeration or loss of liquids after being exposed to moisture or water, severely affecting fertilizer efficiency. Ammonium nitrate, ammonium bicarbonate and other fertilizers have strong hygroscopicity and are easily deliquescent; fertilizers such as ammonium sulfate, ammonium chloride, and urea will form a lump after absorbing moisture, which will not only reduce fertilizer efficiency, but also cause troubles in application. When storing, be careful not to damage the packaging bag, do not pile outdoors, let it wind, snow cover, and sun. It is also necessary to use wooden boards for indoor use. It is 0.3 meters above the ground. The same fertilizer should not be piled too high. Fertilizers should be stored at low temperature and away from light. Nitrogen fertilizers are afraid of heat. Nitrogen will turn into ammonia gas when running out, reducing its effectiveness. In particular, ammonium nitrate is also flammable and explosive. Never mix it with gasoline, alcohol, sulfur, or other flammable materials in a warehouse to avoid accidents. Anesthesia Medical Co., Ltd. , https://www.jssinoanesthesia.com
