1, fast-acting fertilizer should not be mixed with alkaline fertilizer Superphosphate, heavy superphosphate, and other rapidly available phosphate fertilizers used in combination with alkaline fertilizers can cause phosphate degradation, reduce the content of water-soluble phosphorus, and reduce the fertilizer efficiency of phosphate fertilizers. 2, ammonium nitrogen fertilizer should not be mixed with alkaline fertilizer If ammonium bicarbonate, ammonium sulfate, ammonium chloride, ammonium phosphate and other ammonium nitrogen fertilizers are used in combination with alkaline fertilizers, the ammonia will evaporate, causing the loss of nitrogen and reducing the fertilizer efficiency. Alkaline fertilizers include lime nitrogen and grass ash. 3, decomposed organic fertilizer should not be mixed with alkaline fertilizer Highly decomposed organic fertilizers contain more available nutrients, of which nitrogen is mostly in the form of ammonium nitrogen. If used in combination with alkaline fertilizers, the volatilization of ammonia will reduce the nutrient content of organic fertilizers. 4. Nitrate nitrogen fertilizer should not be mixed with organic fertilizer Organic manure contains more organic matter, and when it comes to nitrate nitrogen fertilizer, denitrification will occur and nitrogen will be lost. The commonly used nitrate nitrogen fertilizers include ammonium nitrate and calcium ammonium nitrate. 5, mineral nitrogen fertilizer should not be mixed with uncontaminated organic fertilizer The unripe organic fertilizer contains a large amount of cellulose. When the microorganisms decompose cellulose, they absorb a large amount of mineral nitrogen, convert the inorganic nitrogen into organic nitrogen, and delay the nitrogen fertilizer efficiency. Fire extinguishing protective clothing generally refers to fire protective clothing. Fire protective clothing is one of the important equipment to protect the personal safety of firefighters who are active in the fire front line. Also known as protective clothing, protective work clothing, fire fighting clothing, etc., its structure generally has the characteristics of high coverage, high locking and easy work.
