Anti-tidal metamorphic: If ammonium bicarbonate is easily hygroscopic, resulting in loss of nitrogen volatilization; ammonium nitrate is very hygroscopic, easy to agglomerate, deliquescence; lime nitrogen and superphosphate are easy to agglomerate after absorbing moisture, affecting the application effect. Therefore, these fertilizers should be stored in a dry, cool place, especially when ammonium bicarbonate is stored. The package must be tightly sealed to avoid contact with air. Fire and Sun Avoidance: After nitrogen fertilizers are exposed to sunlight or high humidity, the loss of nitrogen will be accelerated; ammonium nitrate will decompose oxygen in the event of high temperatures, and combustibles will burn when they are burned. Do not crush with hammers when they have become agglomerated. To prevent explosions. Nitrogen fertilizers should be stored in the sun to avoid, no smoking, not with diesel, kerosene, firewood and other items piled together. Anti-volatilization loss: Ammonia and ammonium bicarbonate are very volatile and they must be sealed during storage. Nitrogen fertilizers and superphosphates are strictly prohibited from being mixed with alkaline substances, lime, and ash to prevent loss of nitrogen fertilizers and reduce fertilizer efficiency of phosphate fertilizers. Anti-corrosion Poisoning: Superphosphate is corrosive and prevents contact with skin and metal utensils. Ammonia is strongly corrosive to copper and iron and should be stored in ceramic, plastic and wooden containers. In addition, chemical fertilizers should not be piled up with seeds, and do not use chemical fertilizers in bags to avoid affecting seed germination. China Agricultural Network Editor
