How to store fertilizer
Fertilizer is an important and tight substance in agricultural production. In order not to miss the farm, farmers' friends have rushed to buy and store fertilizers. In order to reduce the loss of chemical fertilizer storage, here are some tips for farmers to pay attention to during the process of chemical fertilizer storage:
First, avoid high temperatures. Studies have shown that: ammonium phosphate is placed in the open air, at a temperature of 16 ° C, the rate of nitrogen loss 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% in 1 day, 48% in 5 days, 77% in 15 days; in the case of temperature 32 °C, the rate of nitrogen loss: 18.9% in 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. Therefore, it is best to buy more fertilizers, try not to have surplus, and summer should be more so. The stored fertilizer should be placed in a cool and dry room, and the temperature should be kept at 10-15 °C.
Second, avoid moist. Fertilizers such as ammonium nitrate and calcium are extremely strong in temperature absorption. When the ground is wet when the air humidity is high, the ammonium nitrate will be lost, and the calcium will lower the active ingredients. Moreover, ammonium nitrate also absorbs agglomerates and can explode when broken. Moisture prevention measures are: try to store in the warehouse, if there is no warehouse, try to store in the shed, rack, and pad the bottom pad, drain the moisture, and then cover it with plastic cloth or linoleum paper to prevent the suction is fast. , reduce fertilizer efficiency.
