How to store chemical fertilizer

Fertilizer is an important and prosperous material for agricultural production. In order not to miss the time, farmers’ friends have rushed to buy and store fertilizer. In order to reduce the loss of chemical fertilizer storage, here are some tips for farmers to pay attention to during the storage of fertilizers:
First, avoid high-temperature ammonium phosphate placed in the open air, in the case of temperature 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; In the case of °C, the nitrogen loss rate is 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 The day was 67.9% and the day was 93.6%. 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, carbon dioxide and water, and are gradually lost. So, how much how much fertilizer is best to buy, try not to have surplus, more so in summer. The prepared fertilizer should be placed in a cool and dry room, and the temperature should be kept at 10-15 °C.
Second, avoid moist ammonia, calcium and other chemical fertilizers are very strong, when the air humidity is high, the ground is wet, ammonium nitrate will "water" loss, calcium will reduce the active ingredients. But also the moisture absorption blocking ammonium nitrate, an explosion will happen when human crush. The method of moisture protection is as follows: store in the warehouse as much as possible. If there is no warehouse, try to store it in the shed and frame, and pad the bottom pad, and protect it from moisture. Then cover it with plastic cloth or linoleum paper to prevent moisture absorption and reduce fertilizer efficiency. .
