First, avoid high temperatures. Studies have shown that: ammonium phosphate is placed in the open air, at a temperature of 16 ° C, the loss rate of nitrogen is: 3.4% for 1 day, 10.6% for 5 days, 18% for 10 days, 26% for 15 days, and 20 °C for 20 days. In the case of nitrogen loss rate: 8.8% for 1 day, 48% for 5 days, and 77% for 15 days; at a temperature of 32 °C, the loss rate of nitrogen is 18.9% for 1 day, 5 days. It is 67.9%, and 93.6% for 10 days. It can be seen from the above data that the higher the ambient temperature, the greater the loss of nitrogen. Nitrogen fertilizers such as ammonium bicarbonate and ammonia water have poor stability. When the temperature exceeds 20 °C, they are easily decomposed into ammonia gas, carbon dioxide and water, which are gradually lost. So, how much how much fertilizer is best to buy, try not to have surplus, more so in summer. The stored fertilizer should be placed in a cool and dry room, and the temperature should be kept at 10-15 °C.
Second, avoid dampness. Ammonium nitrate, superphosphate fertilizer and other highly hygroscopic, when the air humidity when wet ground, ammonium nitrate will "of water" loss SSP reduces the effective ingredient. But also the moisture absorption blocking ammonium nitrate, an explosion will happen when human crush. Moisture way is: try stored in the warehouse, the warehouse if not, to try stored in the shed, frame, and base cushion pad is good, moisture overhead, cloth or felt paper and then covered to prevent rapid absorption junction is reduced fertilizer.
