Recently, a seminar on standardization of healthy development of fertilizer industry was held in Shanghai, sponsored by the National Technical Committee for Standardization of Fertilizers and Soil Conditioners and sponsored by the Journal of Chemical Fertilizer Industry. It was learned from the meeting that the Ministry of Agriculture and Rural Areas, the National Technical Committee for Standardization of Fertilizers and Soil Conditioners, and other departments are sorting out, brewing and promulgating a series of new standards, re-orienting the development direction of fertilizer industry from the top design, and building a food safety and healthy life chain from the source.

Xu Jingying, deputy director of the fertilizer and water saving Department of the Planting Department of the Ministry of Agriculture and Rural Areas, said that the Ministry of Agriculture and Rural Areas had already listed several topics, and other conditions were ripe, and a series of new standards related to the safe and healthy development of the fertilizer industry would be issued.

It is known that the National Technical Committee for Standardization of Fertilizers and Soil Conditioners is currently working on optimizing or formulating relevant standards for the fertilizer industry, including "Limit Requirements for Toxic and Hazardous Substances in Fertilizers" and "Evaluation of Fertilizers for Green Products".

Mao Yongyi, vice president of Shanghai Chemical Research Institute and chairman of the National Technical Committee for Standardization of Fertilizers and Soil Conditioners, explained that after completing the mission of solving the problem of food and clothing, chemical fertilizers have to face the food safety and people's health problems caused by environmental pollution, soil degradation, poor quality of agricultural products. "Safeguarding people's health from the source through the construction of standard system is a new subject for fertilizer industry to explore." Mai Yongyi said.

_Shang Zhaocong, executive deputy director of the National Chemical Fertilizer Quality Supervision and Inspection Center (Shanghai) and secretary-general of the National Technical Committee for Standardization of Fertilizers and Soil Conditioners, believes that the fertilizer industry is facing negative growth in use and some pressure of "demonization" public opinion. It is urgent to focus on "health" and achieve healthy operation of enterprises and industries through the restraint and guidance of the standard system. Develop health, industry chain health, food chain health and life health. According to Shang Zhaocong, the function of chemical fertilizer is being given a new historical task. In the past, chemical fertilizer was used to meet the requirements of food quantity, but now it is necessary to meet the requirements of quality and make food healthier.

Wei Jing, director of Quality Department of China Petroleum and Chemical Industry Federation, said that the current standardization construction of fertilizer industry should focus on two main lines, one is high quality development, the other is green development. Green development has become a national strategy, which is also a task that the chemical fertilizer industry has to complete. In the future, green products, green factories and green parks will be developed at different levels in order to promote the establishment of green manufacturing system in the industry.

_In view of soil conditioners, Chen Mingliang, deputy director and professor-level senior engineer of the Fertilizer Institute of Shanghai Institute of Chemical Research, believes that soil conditioners have been developing actively in recent years, but there are many sources of raw materials, unstable process quality and low technology level of products. More scientific standards are urgently needed to be issued to regulate and guide them.

Ms. Yang Yi, National Technical Committee for Standardization of Fertilizers and Soil Conditioners, introduced that the future fertilizer standard system would be optimized into four parts. Among them, the national mandatory standards are designed to ensure safety and bottom line; recommend national standards to achieve basic universal and mandatory standards supporting; industry standards to unify industry requirements; and group standards to meet market and innovation needs.

_For the optimization of standards, Xu Jingying believes that fertilizer standards include four categories: general standards, product standards, testing standards and safety standards.
