Fertilizer private customization project will be settled in Yangzhou

Recently, the annual “Academician Experts” was formally launched. Eight academicians’ corporate workstations were established, and 12 academicians signed 12 cooperation projects with Yangzhou enterprises. A group of "tall" projects will be settled in Yangzhou.

A team led by Zhu Shiliang, a member of the Chinese Academy of Sciences and a researcher at the Nanjing Institute of Soil Science, Chinese Academy of Sciences, came to Yangzhou to sign a water-based coated controlled-release fertilizer research and development project with Rayou Electric Co., Ltd.

China is a big country for the use of chemical fertilizers, and agriculture and animal husbandry production are inseparable from fertilizers. However, traditional fertilizers have problems of low utilization rate and high pollution. “Some water bodies are very polluted, such as the blue-green algae outbreak in Taihu Lake. These are closely related to the abuse of fertilizers.” Dr. Du Changwen, one of the researchers of the research team of the project and the Nanjing Institute of Soil Science, Chinese Academy of Sciences, said how to produce Fertilizers that are both environmentally friendly and highly utilized are also research topics for many researchers.

“Also, different regions and different crops need different fertilizers.” Dr. Du Changwen, one of the researchers of the project's research team and the Nanjing Institute of Soil Science of the Chinese Academy of Sciences, explained that, to put it simply, they are based on soil and crops. Differently, "private custom" fertilizers for crops.

However, as far as China is concerned, such fertilizers are expensive to produce, and reprocessing may cause secondary pollution. Such products are unwilling to accept for farmers who use fertilizers or for people who use practical crops.

“In the production process of similar products, organic solvents are the materials that must be used, but such solvents are expensive, and the price per ton varies from tens to hundreds of thousands, and it is flammable and explosive.” Du Changwen said, After years of research, the team finally overcomes the difficulties. The core technology is to use water instead of traditional organic solvents. Compared to similar foreign products in the country, the price of domestic products is reduced by 50%-100%, and the controlled release fertilizer finally produced is more environmentally friendly. friendly. "This water-based coated controlled-release fertilizer technology is the first in the world."

"Personally customized" fertilizers for crops may sound unbelievable, but this will soon become possible in the near future. Du Changwen said that the technology is now being developed in cooperation; compared with similar foreign technologies, the project is currently at an international advanced level. I believe in the near future, this new type of fertilizer will bring good news to crops in the north and south of the river.
