Many farmers have the habit of storing chemical fertilizers in winter. The author suggests that the "five preventions" of chemical fertilizers stored in winter can reduce the loss and waste of fertilizers.
One anti-volatile loss
Ammonia and ammonium bicarbonate will continue to decompose at room temperature. The higher the temperature, the faster the decomposition. When farmers store chemical fertilizers, the packaging must be sealed. Nitrogen fertilizer and superphosphate are strictly prohibited to be stacked with alkaline substances (such as lime, plant ash, calcium magnesium phosphate, etc.) to prevent the loss of nitrogen fertilizer and reduce the efficiency of phosphate fertilizer.
Second, prevent moisture deterioration
Most chemical fertilizers are hygroscopic, especially after being drenched in rain, chemical fertilizer nutrients will be lost with water. Some fertilizers will become agglomerated and deliquescence after absorbing moisture. For example, ammonium nitrate will easily agglomerate and deliquify after absorbing moisture, and superphosphate will easily agglomerate after moisture absorption. This type of fertilizer must be stored in a dry, cool and ventilated place.
Three anti-corrosion and poisoning
Some chemical fertilizers contain certain corrosive or toxic substances. For example, superphosphate contains free acid, which is highly corrosive. If this type of fertilizer is stored with the seeds, it will reduce the germination rate of the seeds. Such fertilizers cannot be stored in ironware or wooden barrels for a long time, and they cannot be kept together with seeds, agricultural machinery, etc.
Four preventions mixed with pesticides
Mixing chemical fertilizers and pesticides can easily cause spontaneous combustion and explosion. For example, chemical fertilizers such as sodium nitrate and ammonium nitrate will generate heat when exposed to sunlight and heavy objects, and may cause spontaneous combustion and explosion. Emulsion pesticides contain a large amount of crude benzene, xylene and other volatile and combustible solvents, which will burn quickly once they come into contact with sparks. If you store chemical fertilizers and pesticides together, as long as one side burns spontaneously, it will spread to the other side.
Five-proof mixed storage for long time
There are many kinds of chemical fertilizers and their properties are different, so it is not suitable to be piled or put together. When storing, it should be stored according to the place and type of fertilizer. Acidic and alkaline fertilizers cannot be stored together to prevent nitrogen loss; phosphate fertilizers should not be stored for a long time, because effective phosphorus will gradually decrease during storage; bacterial fertilizers should be protected from heat and sun during storage, ***** *Put it into a black varnished cloth bag to prevent the bacteria in the fertilizer from being sun-dead and losing its effect.
