First, 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. Second, anti-tide deterioration. Such as ammonium bicarbonate is easy to absorb moisture, resulting in loss of nitrogen volatilization; ammonium nitrate is very hygroscopic, easy to agglomerate, deliquescence; lime nitrogen and calcium superphosphate are easy to agglomerate after moisture absorption, 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. Third, anti-volatile loss. Ammonia and ammonium bicarbonate are very volatile and should be sealed during storage. Nitrogen fertilizer and superphosphate are strictly prohibited to be mixed with alkaline substances (lime, grass ash, etc.) in order to prevent the loss of nitrogen fertilizer and reduce the fertilizer efficiency of phosphate fertilizer.
