After spring sowing, most peasants have a certain amount of surplus fertilizer in their homes. If these fertilizers use some unreasonable storage practices, they will not only cause loss of nutrients and inconvenience for later use, but may also cause accidents such as explosion, burning, and poisoning. Therefore, “five preventions†must be implemented during the storage and storage of chemical fertilizers.
1, anti-moisture agglomerate
The humidity or agglomeration of chemical fertilizers due to moisture absorption is a common problem in storage. The more serious the air humidity is. Fertilizers should be placed in a dry, cool warehouse with stacking distances of 30-50 cm from the wall, storage temperatures below 30°C, and relative humidity of 40-70%.
2, anti-nutrient volatile
For fertilizers with poor stability, ammonium bicarbonate, for example, must be packed tightly, kept dry, and protected from direct sunlight. Should be used with the use, use a bag and then remove a bag, use the remaining fertilizer to tie the bag mouth. For ammonium nitrogen fertilizers such as ammonium chloride, ammonium sulfate, ammonium nitrate, ammonium bicarbonate, etc., care must be taken not to mix them with the alkaline fertilizer in order to reduce nitrogen loss.
3, anti-corrosion damage
Fertilizers are generally corrosive, especially acidic fertilizers such as superphosphate and ammonium chloride. During the storage process, volatile acids are easily generated. Do not put farm implements such as sprayers, ploughs, and iron buckets together with chemical fertilizers for a long time. Corrosion damage.
4, anti-poisoning
Can not put ammonium bicarbonate, urea, ammonium nitrate, superphosphate and other fertilizers stored together with the seeds, otherwise it will affect the seed germination rate, in serious cases will make the seeds lose their germination ability. In addition to this, foods, pesticides, feeds, bacteria and chemical fertilizers cannot be mixed to avoid poisoning accidents.
5, fire prevention and explosion
Special attention should be paid to nitrates in the storage of chemical fertilizers. Do not stack them with flammable materials. Once caught in the fire, various chemical extinguishing agents cannot be used. They should be stamped with sand and then extinguished with water.
