Farm supplies fertilizer is one of the farmers brother standing at home, so pay attention to the storage of fertilizers: anti-back tide deterioration ammonium bicarbonate is hygroscopic, resulting in nitrogen volatilization loss; very hygroscopic ammonium nitrate, easy caking, deliquescence; lime nitrogen and over Calcium phosphate is easy to agglomerate after moisture absorption, which affects the application effect. Therefore, these fertilizers should be stored in a dry, cool place, especially when storing ammonium bicarbonate, the package should be sealed firmly to avoid contact with air. After the fire of nitrogen fertilizer to avoid the sun when the temperature or by the sun, would accelerate the volatilization loss of nitrogen; oxygen will break down when the temperature of ammonium nitrate, will burn combustible case, we do not have lumps with a hammer blow to Anti-explosion. Nitrogen fertilizers should be stored in the sun, no fireworks, and should not be stacked with diesel, kerosene, firewood and other items. Anti-volatile loss Ammonia water, ammonium bicarbonate is very volatile, and should be sealed when stored. Nitrogen fertilizers and superphosphates are strictly prohibited from being mixed with alkaline substances (lime, grass ash, etc.) to prevent loss of nitrogen fertilizer and reduce the fertilizer efficiency of phosphate fertilizer. Corrosion-resistant and toxic super-calcium phosphate is corrosive and should be protected from contact with skin and metal utensils. Ammonia water is highly corrosive to copper and iron and should be stored in ceramics, plastics and wooden containers. In addition, fertilizers cannot be stacked with seeds, and do not use fertilizer bags to seed, so as not to affect seed germination.
