Some people think that winter temperatures are low, chemical fertilizers do not evaporate, and they are not corrosive. This is not the case. ?
Ammonium bicarbonate, ammonium sulfate and Other nitrogen fertilizers are not non-volatile at low temperature, but they are slower in volatilization and less volatile than summer and autumn high temperature seasons; the corrosiveness of superphosphate is not much related to the temperature, sacks, As long as the sack is exposed to superphosphate, it will be corroded and the contents of the bag such as seeds, salt, soda, etc. will deteriorate. In addition, the nitrogen vapor after the evaporation of vapor in the air will be converted into a strong corrosive ammonium hydroxide, the embryo will lose seed germination, so that food deterioration, so that pesticides failed. ?
In view of the above reasons, the “four preventions†are also required to store chemical fertilizers in the cold season. ?
Anti-volatilization: Many nitrogen fertilizers, such as ammonium sulfate, ammonium bicarbonate, ammonium nitrate, etc., due to their extremely unstable nature, can easily decompose 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.
Waterproof and moisture-proof: nitrogen fertilizer is easy to agglomerate or lose water after being dampened or wet. During storage and storage, we must pay attention to keep the storage environment dry, and prevent breakage of the bag.
? Anti-pollution: ammonia can not be placed in the bedroom, hall, in order to avoid volatile ammonia gas stimulate people's eyes, nose and respiratory tract, endangering health. Anti-corrosion: ammonium bicarbonate, 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.
