The world's first stable fertilizer standard will be introduced

[Editor's Statement] The forthcoming "Standard for Stabilized Fertilizer Industry" sets clear requirements for fertilizer requirements, test methods, inspection rules, labeling, packaging, transportation and storage, and applies to nitrogen, phosphate, potash, and compound fertilizers. , fertilizer and other products processed from the stable fertilizer. Experts pointed out that the new standard will play an important role in the sustainable and healthy development of the stable fertilizer industry, the quality of stable fertilizer producers, the regulation of markets, and the protection of consumer rights.

The reporter learned from the press conference for the 2010 stable fertilizer industry development forum and stable fertilizer industry standard held on November 13 that the “Stable Fertilizer Industry Standard” has been approved by the Ministry of Industry and Information Technology and will be introduced around June next year. This is the industry standard for the first stable fertilizer in the world. Experts said that the introduction of the standard marks the start of growth of stable fertilizers as a new industry.

The forthcoming "Stable Fertilizer Industry Standard" sets out clear requirements for fertilizer requirements, test methods, inspection rules, marking, packaging, transportation, and storage, and is applicable to nitrogen fertilizer, phosphate fertilizer, potash fertilizer, compound fertilizer, compound fertilizer, etc. Stable fertilizer made from processed products. Experts pointed out that the new standard will play an important role in the sustainable and healthy development of the stable fertilizer industry, the quality of stable fertilizer producers, the regulation of markets, and the protection of consumer rights.

According to Shi Yuanliang, a researcher at the Shenyang Institute of Ecology, Chinese Academy of Sciences, stable fertilizers belong to a new type of compound fertilizer, in which urease inhibitors (or nitrification inhibitors) have been added by special processes, and they can inhibit urea hydrolysis and nitrification through urease when applied to the soil. The inhibitors inhibit the nitrification of ammonium nitrogen, activate the phosphorus in the soil, increase the utilization of nitrogen and phosphorus, and increase the fertilizer efficiency, so that one fertilization is not required for top dressing. Compared with common chemical fertilizers, the effective nitrogen content of stabilized fertilizers increased by 60% to 120% when applied for 120 days, and the utilization rate of fertilizers could be increased to 42% to 45%.

According to Shi Yongfeng, chairman and general manager of Shi Ke Feng Chemical Co., Ltd., stable fertilizers can improve long-term fertilization and low utilization rates of domestic fertilizers, especially the low nitrogen and phosphorus utilization rate. Utilization rate increased by 12-15 percent. He explained that the nitrogen release period of ordinary nitrogen fertilizer is about 45 days, and the utilization rate is lower than 30%. Excessive use of chemical fertilizer not only causes waste of resources and economic losses, but also pollutes the ecological environment. According to the test, the stabilized fertilizer lasted for 120 days and was able to meet the nutrient requirements of most crops throughout the growth cycle. It can save 20% to 30% of fertilizer and increase the average yield per mu by 18.5%. The output of field crops such as rice and maize can be increased. Increase by more than 20%. At present, there are more than 6.5 million mu of stable long-term sustained-release compound fertilizer demonstration fields and more than 200 demonstration bases throughout the country, and more than 24 million mu of cultivated land have been promoted in 26 provinces, municipalities, and autonomous regions nationwide.

It is understood that the slow-release fertilizer represented by stable fertilizers has ushered in a period of rapid development in recent years. At present, the global production capacity of controlled-release fertilizers has reached 7 million tons, and the annual production of controlled-release fertilizers is more than 2 million tons. However, there is no corresponding bidding or national standard in the world.
