What is ammonium phosphate polyphosphate?

China's phosphate fertilizer industry is experiencing the pain of structural reforms. Overcapacity, product homogeneity and low promotion efficiency are three major problems that plague domestic phosphate fertilizer enterprises. The core of solving problems lies in technology upgrading, product innovation and resource science utilization. Among the new types of phosphate fertilizers that have emerged, ammonium polyphosphates, which have excellent solubility and compatibility, stand out and attract widespread attention in the industry.

Recently, at the "China Agricultural Ammonium Polyphosphate Liquid Fertilizer Application Seminar" hosted by China Cooperation Times, China Agricultural Materials Media and Yanfu (Group) Co., Ltd., the reporters talked about the leadership of relevant national departments, domestic liquid fertilizer Authoritative experts in production, R&D and promotion, as well as representatives of leading enterprises, focus on the market positioning and application prospects of ammonium polyphosphate liquid fertilizer, and jointly explore the promotion mode and profit model of product homogenization era.

Ammonium polyphosphate meets new demands for scientific fertilization

“Adjusting structure and transferring mode” is a phased goal of the domestic fertilizer industry and a major challenge to the development of fertilizer enterprises. For China's phosphate fertilizer, the transition from quantity to quality, from imitation to innovation, will be the theme of future development.

According to Zhang Shuqing, director of the Fertilizer Engineering Technology Research Center of the Chinese Academy of Agricultural Sciences, the product structure of China's phosphate fertilizer should be developed in the direction of high efficiency, compounding and liquefaction. The phosphate fertilizer process should be developed from extensive to refined. It is against this background that ammonium polyphosphate has entered China as a high-end liquid phosphate fertilizer across the ocean.

What is the role of ammonium polyphosphate in the agricultural sector? There is no doubt in the industry. In this regard, Zhang Chenglin, a professor at South China Agricultural University, said: “Ammonium polyphosphate, a core raw material for liquid fertilizer, has been used in the United States for more than 50 years. In North America, the production of liquid fertilizer with ammonium polyphosphate solution is a common As a raw material, ammonium polyphosphate can be added with a large number of elements, medium elements, trace elements or amino acid additives to form a variety of formulations to cope with different soils and different crops."

It is true that learning from domestic and foreign experience has become the consensus of the fertilizer industry. According to Tu Shihua, deputy director of the Southwestern Region of the United States International Plant Nutrition Institute, the use of ammonium polyphosphate in the United States is still expanding, with an annual consumption of about 2 million tons in 2015-2016. At present, the North American market accounts for 90% of the total amount of agricultural ammonium polyphosphate in the world.

Tu Shihua said: "In specific applications, we can use ammonium polyphosphate as a slow-acting fertilizer, a raw material for formula fertilizer. It can be said that the emergence of ammonium polyphosphate provides more choices for precise fertilization."

In this regard, Zhang Chenglin strongly agrees. “Ammonium polyphosphate is widely used in corn fertilizers abroad, which is consistent with the concept of domestic seed fertilization. Ammonium polyphosphate can provide nitrogen and phosphorus, which greatly promotes the growth of crop seedlings. In addition, suspension based on ammonium polyphosphate Fertilizer can be used as a base fertilizer, and it can also be applied to foliar application after sequestration of trace elements."

Practice is an effective way to test the effectiveness of fertilizers. In the field of fertilizer research and development, many domestic experts have included ammonium polyphosphate into the field of vision. Chen Mingliang, deputy director of the Chemical Research Institute of Shanghai Research Institute of Chemical Industry, said: "The Shanghai Research Institute of Chemical Industry has been studying ammonium polyphosphate since 1985. It has done a lot of experiments on the fertilizer field. The results show that the use of ammonium polyphosphate for barley, Rape, tomato, strawberry and other crops are sprayed on the foliar surface, and the yield increase is 10%-30%. The effect is considerable. At the same time, the characteristics that can be absorbed after the ammonium polyphosphate conversion can help to prolong the fertilizer efficiency, and the nutrient application rate is relatively high. ”

The economics of ammonium polyphosphate has received much attention compared to solid fertilizers. Tu Shihua said: “The farmer believes that the application of liquid fertilizer is convenient, the dosage and use position are accurate, and the labor is saved. The material basis supporting this view is the whole set of fertilization system, in which transportation cost is an important issue. Liquid fertilizer sellers vs. customers The service radius is usually within 50 km, generally not more than 80 km, otherwise the economic benefits will be greatly reduced."

At present, the domestic ammonium polyphosphate industry is still in its infancy, and it needs to be explored through large-scale experimental demonstrations. Before the ammonium polyphosphate was widely used in the market, the domestic leading phosphate fertilizer enterprises have begun to take the lead. At present, the ammonium polyphosphate project with an annual output of 200,000 tons has been put into operation, and plans to expand production to 350,000 tons per year at the end of the 13th Five-Year Plan.

Dr. He Yu, a researcher at the Fufu Industrial Research Institute, said: "After accumulating more than 50 years of experience, the United States has formed a series of industry standards for the production and application of ammonium polyphosphate. We can fully learn from foreign advanced experience and can take less Detours, with less effort. From the products of our company, '瓮福' ammonium polyphosphate has less metal ions, which provides a large operating space for the addition of trace elements in agricultural applications."

Fertilizer promotion should be based on the current situation of China's agriculture

Whether it can adapt to local conditions and meet the needs of China's agricultural development is an important criterion for testing fertilizers. In the process of modern agricultural development in China, the protection of the ecological environment must be given priority, and the desire of farmers to produce high yields and increase income must also be met.

Wang Xinlong, a professor at the School of Chemical Engineering at Sichuan University, said that ammonium polyphosphate is limited by resources, technology, and prices. It is still unclear whether it is possible to replace phosphate fertilizer products and even upgrade products. Zhang Shuqing also said: "In the promotion of ammonium polyphosphate, it is necessary to consider technical issues, but also to examine its feasibility with economic and market perspectives.

At the current level of agricultural development, there may still be a distance from the promotion of Daejeon. The promotion of high-end products, farmers will not use, economics can be guaranteed to think seriously. In particular, fertilizers should be developed based on the leading industries of agriculture. The promotion and sales of products should be comprehensively analyzed in combination with soil, ecology and crop types, so that they can be targeted. Focus on the key demand areas, the market acceptance will be better. ”

Agricultural production is inseparable from fertilizers, and the scientific use of fertilizers directly affects the quality of cultivated land and soil health. Wang Xu, secretary general of the Soil and Fertilizer Industry Alliance of the Chinese Academy of Agricultural Sciences, believes that domestic fertilizer companies are facing great market pressure, and how to survive is a key issue. At the same time, national ecological agriculture and ecological civilization construction have also continuously put forward new requirements for agricultural development.

"On the one hand, we must survive, on the one hand, we must keep up with the development orientation of the times. For enterprises, it is essential to improve the service level." Wang Xu said: "To do farmland and sell fertilizers, we must first let the concept be in line with the times. At the core, solving local problems, docking local resources, and understanding farmers' needs can make fertilizer promotion smooth all the way. Ecological agriculture is the top design of the country, and the service must be 'grounded gas'. It is worthwhile to try to promote the service with the service."

In view of the difficulty in promoting high-end liquid fertilizer, Gao Xiangzhao, chief expert of the National Agricultural Technology Promotion Center of the Ministry of Agriculture, said: “Liquid fertilizer is an important carrier for the development of water and fertilizer integration. For specific products, according to their characteristics, according to different regions, it is necessary to distinguish More importantly, the fertilizer should be coordinated with the agricultural machinery and with the fertilization method.

Irrigation and fertilization is a form of water and fertilizer integration. Promoting water and fertilizer integration can promote many new agricultural products, including new liquid phosphate fertilizers such as ammonium polyphosphate. Such products will have a wide range of development space, and enterprises and promotion units should systematically research and actively pilot and deliver quality products to the front line of agricultural production. ”

Liquid phosphate fertilizer drives industrial transformation and upgrading

“Chinese fertilizer has entered a new era of equal development of nutrients, equivalent forms, contents, and additives. The same nutrients and different additives can be used in different fertilizers.” Gao Xiangzhao said: “Chinese phosphate fertilizer from superphosphate The development of calcium to monoammonium, diammonium, potassium dihydrogen phosphate and compound fertilizers is always improving. The ammonium polyphosphate we see now is a brand new product for domestic agriculture. We hope that ammonium polyphosphate The development can drive China's phosphate fertilizer industry to achieve a big progress and change.

Because fundamentally, the domestic phosphate fertilizer utilization rate is not high, and it has a lot to do with the phosphate fertilizer product itself. At present, the utilization rate of domestic phosphate fertilizer is only about 18%. If the utilization rate reaches 33% and 34%, theoretically, it can reduce the consumption of phosphate ore by about half. Reducing consumption and conserving resources through innovative products should be a major inspiration for the industry. ”

“China's phosphorus chemical industry still has room for development, and the adjustment of industrial structure and product structure is the highlight.” Wang Xiaofeng, deputy director of the Industrial Development Department of the China Petrochemical Federation, affirmed this view: “The current traditional bulk chemical products are generally surplus, including The product innovation of monoammonium, diammonium and phosphate fertilizer industry can't stop. From the ammonium polyphosphate, if it can rely on product characteristics to achieve true balanced fertilization and precise fertilization, its promotion and application will be for the whole industry. Revolutionary.

In this regard, He Guangliang, the chairman of Haofu (Group) Co., Ltd., made a clear echo: “The “13th Five-Year” action plan of Yanfu Group has been completed, and the company plans to invest more than 22 billion yuan to implement 350,000 tons of polyphosphoric acid. The planning of ammonium, 80,000 tons of potassium dihydrogen phosphate, and more than 130 projects in Guizhou water and fertilizer integration.

Strive to achieve 1.02 million tons of new products such as water-soluble fertilizers by 2020, accounting for more than 30% of the product line. Yufu has formed the industrial layout of Gansu, Sichuan and Fujian with Guizhou R&D base as the center. Radiating the majority of the Chinese market for the center, this distributed industrial layout is a natural advantage for the promotion of ammonium polyphosphate.

I believe that with the deepening of the national 'one control, two reductions and three basics' policy, the concept of environmentally friendly, scientific trial, and full service is the trend of the times. The liquid fertilizer represented by ammonium polyphosphate has broad development prospects. ”

What is the change of ammonium polyphosphate, a high-end liquid phosphate fertilizer, to China's phosphate fertilizer industry? Yang Sanke, general manager of Haofu Group, said: “Ammonium polyphosphate is a commercialized, bulky commodity in North America. The road is worthy of our reference in the process of developing modern agriculture. At the same time, ammonium polyphosphate is an upgraded product, its technical improvement, and the improvement of supporting services have reference significance for domestic phosphate fertilizer enterprises. I hope to explore and demonstrate in this regard."

In addition, due to limited domestic time, large-scale production is short-lived, and the current industry standard for ammonium polyphosphate is still blank. Sun Yizhong, executive director of the Bid Standard Technology Research Institute Co., Ltd. believes that the formulation of group standards is crucial for protecting products and maintaining industry order. “I think the standard prototype is relatively clear.”

He said: "The mainstream enterprises in the industry participate in the formulation of group standards and simultaneously turn into national standards. From a professional perspective, this channel is completely exist. From the perspective of industry health, the quality and application level of standard setting is of great significance. It determines whether this product can gain a pure land in the fierce market competition."

Representatives of the conference discussed the targeted development of ammonium polyphosphate products. Experts have devoted their efforts to generously donating years of experimental data and practice. Enterprises are also dedicated to wisdom, sharing the experience of application, promotion and practice with the industry. With the help of this meeting, China Agricultural Materials Media conducted a comprehensive review of ammonium polyphosphate products through interviews and interviews with experts and business representatives, and successfully made this meeting a peak dialogue on water and fertilizer upgrading.

Just like Zeng Feng, editor-in-chief of China Agricultural Media, said: "We strive to thoroughly analyze this product, and use the wisdom of experts and enterprises to make a small variety of ammonium polyphosphate as a farmer with scientific attitude and objective judgment. The big pattern of the asset industry." (China Agricultural Resources Network, Wu Jiang Xu Wei Hu Yulin Lei Yaru)
