Q: how should fertilizers be packaged and stored? Especially for large grain producers and fertilizer distributors, in high-temperature and rainy areas, where should the fertilizer warehouses be built?
A: the key to storage is to prevent chemical fertilizers from moisture clots, nutrient loss, corrosion, poisoning and fire. Therefore, chemical fertilizer warehouses should be built on high ground, dry, rainproof and fireproof conditions, without water accumulation. Acid fertilizer have corrode action, need to use urea fertilizer packing machine, cannot use cloth bag, paper bag and iron implement store, want to put in tile cylinder or plastic bag. Antisepsis is fertilizer cannot be mixed with seed, pesticide, bacterium fertilizer puts or direct contact. Fire prevention is to ammonium nitrate, potassium nitrate and other inflammable and explosive, away from the fire source, and prepare some sand for extinguishing.

Q: how do fertilizers stack up in warehouses? What if the warehouse doesn't fit?

A: the fertilizer should be separated from the wall by 30 to 50 cm, using high palletizing machine, cross
stacking, layer by layer stacking code. Generally, the height is no more than 8 ~ 12 storeys. Double woven bags can be higher, but should not be more than 7 meters. Keep footpaths between stacks, different fertilizer varieties, for moisture resistance and inspection. When the amount of fertilizer is large, the fertilizer should be numbered and recorded.

Q: will the storage of fertilizers expire after a long time? Does the state have such regulations?

A: generally speaking, want to use professional bag sewing machine, and store proper, long-term storage also won't produce big effect to fertilizer quality. But if the seal is not good or damp, fertilizer is easy to agglomerate, fertilizing bring inconvenience. The nitrogen loss of urea and ammonium nitrogen was also observed. The available phosphorus content in phosphate fertilizer may decrease, but the total amount of phosphorus does not change much.
