1. Deliquescent, agglomeration and nutrient loss caused by moisture absorption of moisture-proof chemical fertilizers are common problems in storage. For example, after the calcium is damp, it is not only easy to agglomerate, but also causes difficulty in application, and effective phosphorus degeneration occurs. The ammonium bicarbonate decomposes and volatilizes after moisture, and the nitrogen runs away; ammonium nitrate, nitrophosphate, potassium nitrate, calcium nitrate, urea, etc. And the use of these mixed fertilizers are very easy to absorb moisture, agglomerate, difficult to apply and lose a lot of nutrients. Prevent the loss caused by chemical fertilizer moisture absorption: First, keep the fertilizer bag intact, because the plastic bag has moisture-proof effect, and the vehicle with the fertilizer should be flattened, no nail head, pile, etc., and it should be covered with rain and sun protection. Second, the warehouse is required to be well ventilated, watertight, and dry on the ground. It is best to lay a layer of moisture-proof linoleum and wooden slats.
2, anti-corrosion and anti-virus fertilizer consists of various acids, alkalis, salts: 1 some are toxic such as lime nitrogen; 2 some are volatile in the storage of free acid, so that the warehouse air is acidic, such as calcium; 3 some deli After the ammonia gas is volatilized, basic substances such as ammonium bicarbonate, ammonium chloride, ammonium sulfate and ammonium-containing compound fertilizer are formed in the space; 4 some local heat often produce nitrogen dioxide NO2, nitrous oxide Harmful gases such as N2O, such as ammonium nitrate, calcium nitrate, and nitrophosphate, contain nitrogenous nitrogen. If seeds, grain or pesticides are stored in the warehouse at the same time, the seeds will lose their germination rate, the grain will deteriorate, and the pesticides, especially the powders, will be more easily decomposed and failed. Other items that are afraid of corrosion should not be placed in the warehouse with fertilizer. Responsible for the warehouse staff to bring masks and gloves, the warehouse should be ventilated, the temperature is below 30 ° C, and the relative humidity is less than 70%. When the temperature and humidity in the warehouse are higher than the outside of the warehouse, the natural doors and windows of the warehouse can be opened in the morning and evening on a sunny day; the summer can be carried out after the night and when the temperature is low.
3, fireproof and explosion-proof ammonium nitrate, potassium nitrate (common name fire nitrate), etc. are the raw materials for the manufacture of gunpowder, exposed to sunlight, impact or heat, spontaneous combustion, explosion under the influence of high temperature. Do not contact such flammable materials when storing such fertilizers. Do not pile up too much when stacking chemical fertilizers. It is better to use no more than 1.5 meters when palletizing. Fireworks should be strictly prohibited in the warehouse, and fire-fighting equipment should be set up to ensure safety.
Precautions for common fertilizer storage
There are many varieties of fertilizers and their properties are different. When storage, corresponding measures must be taken to reduce fertilizer losses. Precautions for chemical fertilizer storage are:
