Fertilizers need to be purchased in advance for the urgent use of the production season. However, if the fertilizers are bought and returned home, if they are not properly kept, they will cause loss of nutrients, reduce fertilizer efficiency, or cause agglomeration of fertilizers, which will cause difficulty in application. So how do you store fertilizer? Specifically, we must do a good job of "five preventions." 1. Anti-humidity: Any chemical fertilizer should be stored in a cool and dry room, otherwise it will cause hygroscopic deliquescence, reduce fertilizer efficiency, and also cause agglomeration of fertilizer and inconvenience of application. If the superphosphate is not stored at the same time, it not only causes hygroscopic agglomeration, but also causes the phosphate fertilizer to reduce its effectiveness. Second, anti-fertilizer mixing: different types of fertilizers should be stacked separately, do not mix and bulk, in order to prevent the interaction of different types of fertilizers, causing chemical changes, loss of nutrients, especially alkaline fertilizers should not be with ammonium nitrogen and superphosphate Calcium is mixed together. At the same time, be careful not to wear labels on the fertilizer bags to avoid mixing and misuse. Third, fire prevention and water. Nitrite fertilizers with combustibility, such as potassium nitrate and sodium nitrate, should not be stored together with flammable materials such as sawdust and sulfur. Can't smoke and ignite in the room where the fertilizer is stored to prevent fire. Most of the fertilizer is soluble. Therefore, the room where the fertilizer is stored should be protected from leakage so as to prevent the fertilizer from getting wet. Fourth, antisepsis and poison: Some fertilizers are corrosive or toxic. If lime nitrogen is toxic to humans and animals, it should be in the upper hand when handling and applying it. It is best to wear masks and goggles. Another example is superphosphate, which contains a certain amount of free acid and is corrosive. It cannot be stored in bags or ironware. It should generally be placed in a dry place or stored in tile jars and wooden barrels. 5. Anti-air contact: Containers for storing fertilizers should be covered and sealed. Chemical fertilizers packaged in plastic bags should be used with the open packs to prevent nitrogen from escaping after contact with air. China Agricultural Network Editor
