In rainy seasons, chemical fertilizers should generally be stored in warehouses. The Kunei must be ventilated and cooled, and it must be dry and moisture-proof. Fertilizers are stored in warehouses in two ways, bulk storage and bag storage. For nitrogen fertilizers with strong hygroscopicity, such as ammonium nitrate, it is necessary to use bags to avoid stacking. Double bags are used for packaging and outer woven bags are lined with plastic bags. Whether bulk storage or bag storage, in order to avoid agglomeration, the storage pressure should be reduced, and the height of the bulk and bales should be controlled.
Select the storage shed to store fertilizers. Be extremely careful during the rainy season. The location of the shed should be high, dry, and ventilated, and the roof should be protected from rain.
