In recent years, due to factors such as the low prosperity of domestic crops and environmental protection and production restrictions, China's phosphate fertilizer production capacity and output have begun to shrink. According to the data of the China Phosphate Compound Fertilizer Association, the total output of phosphate fertilizers in China in 2018 was 16.963 million tons, down 0.9% year-on-year, of which 16.101 million tons of high-concentration phosphate fertilizers, up 0.2% year-on-year, and 863,000 tons of low-concentration phosphate fertilizers, down 18.1% year-on-year. The output of monoammonium phosphate and diammonium phosphate in 2018 was 15.092 million tons and 16.238 million tons, respectively, a year-on-year increase of 10.18% and 0.61%.

In the future, the

environmental protection pressure of the chemical industry, including phosphate fertilizer, will exist for a long time, and the supply of phosphate fertilizer in China will continue to shrink.

In 2018, the output of the top 5 provinces in domestic phosphate fertilizer production accounted for 85.7% of the total phosphate fertilizer output in the country

, and the output of the top 10 enterprises accounted for more than 63% of the total phosphate fertilizer output in the country. With the continuous development and growth of domestic phosphate fertilizer production enterprises, especially in recent years, mergers and acquisitions have increased, mergers and acquisitions have increased, the number of basic fertilizer enterprises has decreased, and large-scale, comprehensive, cross-industry and cross-regional enterprise groups have increased, and the concentration of China's phosphate fertilizer industry has increased significantly.
