Ammonium bicarbonate, ammonium sulfate and other nitrogen fertilizers are not non-volatile at low temperature, but they are slower in volatilization rate and less volatile than summer and autumn high temperature seasons; ammonium nitrate, potassium nitrate, sodium nitrate and other nitrogen fertilizers are stored in kitchens or heating stoves. On the other hand, it is also prone to burning and explosion; the corrosion of superphosphate is not much related to the temperature. Bags, sacks, etc., as long as they come in contact with superphosphate, will be corroded. The contents of the bag such as seeds, salt, soda, etc. It will degenerate. In addition, the nitrogen vapor after the evaporation of vapor encountered in the air, will be converted into a strong corrosive ammonium hydroxide, so that the seeds of embryos lose the germination force, food deterioration, pesticide failure.
In view of the above reasons, the “five preventions†for the storage of chemical fertilizers in the cold season are as follows:
1, anti-volatility. Many nitrogen fertilizers, such as ammonium sulfate, ammonium bicarbonate, ammonium nitrate, etc., due to their extremely unstable nature, are easily decomposed and evaporate during storage and reduce fertilizer efficiency. Therefore, such fertilizers should be stored in airtight plastic bags or other sealed and corrosion-resistant containers.
2, waterproof and moisture. Nitrogen fertilizers tend to agglomerate or lose water after being exposed to moisture or water. During storage and storage, care must be taken to keep the environment dry and prevent breakage of bags.
3, fire prevention. Ammonium nitrate is flammable and flammable. It easily oxidizes at high temperatures and burns or explodes. Therefore, beware of fire when storing, do not go near stoves, or store them together with flammable materials to prevent chemical reactions between them.
4, anti-pollution. Ammonia fertilizer, etc. can not be placed in the bedroom, hall, so as to avoid volatile ammonia gas stimulate people's eyes, nose and respiratory tract, endangering health.
5, anti-corrosion. Carbon ammonia, superphosphate, etc. cannot be stored in sacks, sacks, and paper bags and should be stored in plastic bags or porcelain jars. All kinds of chemical fertilizers cannot be stored in a house with seeds, grain, oil, farm implements, etc.
