Storage and storage of winter and spring fertilizers

Every winter, farmers in their hands store the fertilizer that was left in the year or purchased for the spring of next year. Some people do not understand the nature of chemical fertilizers, neglecting scientific management, and arbitrarily stacking, which not only reduces the fertilizer efficiency, but also is prone to danger. Various fertilizers have different characteristics, some are acidic or alkaline, some are corrosive or toxic, some are very easy to absorb moisture and agglomerate, some are volatile and lost, and some are flammable and explosive. In particular, after entering the spring, the warehouse is moderately enlarged. According to the different characteristics of various fertilizers, proper storage methods must be adopted to avoid deterioration or reduce fertilizer efficiency.

Different kinds of chemical fertilizers should be stored in the warehouse in a single storage, labelled, marked with the name and chemical composition, must not be mixed. Ammonium-nitrogen fertilizers such as ammonium sulfate, ammonium hydrogen nitrate, ammonium chloride and ammonia water are likely to cause nitrogen volatilization and reduce fertilizer efficiency when encountering alkaline fertilizers such as ash, lime and lime nitrogen; nitrate nitrogen fertilizers such as ammonium nitrate and sodium nitrate When the superphosphate is mixed, the fertilizer will deliquesce, causing the nitrate nitrogen to gradually decompose and become a gas to run away, causing undue loss.

Fertilizer should be stored in a dry place in the warehouse, waterproof and moisture-proof. Fertilizers are generally soluble in water. They are easily agglomerated or become liquid after being damp or wet, which seriously affects fertilizer efficiency. Fertilizers such as ammonium nitrate and ammonium bicarbonate have strong hygroscopicity and are highly deliquescent; ammonium sulfate, ammonium chloride, urea and other chemical fertilizers will form a hard block after moisture absorption, which will reduce the fertilizer efficiency and bring trouble to the application. When storing, be careful not to damage the bag, do not pile it up outdoors, let it wind, snow cover, and sun. Also use wooden boards to make up indoors. Do not pile up the same fertilizer more than 0.3 meters above the ground.

Fertilizer should be stored in a place protected from low temperature and light. Nitrogen fertilizer is afraid of heat. After heat, nitrogen will turn into ammonia and run away, reducing the effectiveness. In particular, ammonium nitrate is flammable and explosive. Never mix it with flammable materials such as gasoline, alcohol or sulfur in a warehouse to avoid accidents.
