Winter is the off-season application of chemical fertilizers, but most farmers have the habit of storing fertilizers in winter. Storage of chemical fertilizers in winter must be strengthened. Otherwise, it will not only result in the loss of fertilizers, but also cause serious accidents.
Anti-volatile loss
Ammonium bicarbonate is an unstable compound that easily decomposes itself into ammonia, carbon dioxide, and water, causing loss of nitrogen. The higher the temperature, the faster the decomposition, so it must be firmly sealed during storage. Nitrogen fertilizers and superphosphate are strictly prohibited from being mixed with lime, plant ash, calcium magnesium phosphate, etc., in order to prevent the loss of nitrogen fertilizers and reduce the fertilizer efficiency of phosphate fertilizers.
Anti-absorbing agglomerate
Most of the solid fertilizers are hygroscopic, and some are even degraded after damp. Such as ammonium bicarbonate easy to absorb moisture loss caused by ammonia volatilization; potassium chloride has hygroscopicity, moisture easily form a block; ammonium nitrate moisture is easy to caking, deliquescence and so on. Therefore, it must be placed in a dry, cool, ventilated place, storage should be first with masonry, wood or other things trend moisture moisture. The height of chemical fertilizer stacking should not exceed 2 meters in general, and the time should not be too long, so as to prevent caking and increase the difficulty of application.
Anti-corrosion poisoning
Chemical fertilizers are generally corrosive, especially strongly acidic and strongly alkaline fertilizers, which are more corrosive. These fertilizers are currently used for storage. The gas they evaporate has a pungent odor that is toxic to the human body and should be avoided by long-term direct contact. We must not mix toxic fertilizers with food, feed, and agricultural and sideline products to prevent human and animal poisoning. Http://
