Brazil, India, Southeast Asia and other countries. At present, the measures to solve this problem are to increase the development of China's own potassium resources, continuously strengthen the utilization of potassium resources in neighboring countries, and strengthen the means of import negotiation between China and other international importers. However, the supply capacity of China's own potassium salt is difficult to exceed 3.5 million tons before 21, and the potassium resources in Thailand, Laos and other countries that are being developed cannot form a scale before 215, and the maximum substitution capacity can only reach 3 million tons. Therefore, it is difficult for China potash fertilizer to get rid of the shackles of imports for a long time. At present, influenced by the development of bioenergy, the global demand for potash fertilizer is increasing by more than 1 million tons every year, which leads to the global supply of potash fertilizer tightening. Potash fertilizer suppliers have mastered this thread. Even if China reaches an offensive and defensive alliance with Brazil, India, Southeast Asia and other countries, it is difficult to reverse the trend of price increase and fundamentally solve the passive situation of potash fertilizer import.

The cultivated land in China is short of potassium, and the potassium salt used for potash fertilizer production is a scarce mineral resource in China, and it has long relied on imports to meet the demand of agricultural production. The demand of potash fertilizer in China has been increasing at a higher rate than that of nitrogen fertilizer and phosphate fertilizer < P > According to the analysis of the industry, potash fertilizer is not in global shortage like other fertilizer raw materials, and it is concentrated in Canada, Russia, Israel, Jordan and the Middle East, controlled by a few countries, and its price is basically in a monopoly position. In recent years, agriculture in South America, Southeast Asia and other regions has developed rapidly, and the demand for potash fertilizer is increasing every year.

According to reports, there are mainly two kinds of potassium fertilizers in China at present: potassium sulfate and potassium chloride. Wanxiang company is about to introduce potassium nitrate, which can be used for nitrogen as well as potassium. It is a chlorine-free potassium and nitrogen compound fertilizer. At present, this kind of potassium nitrate is seldom used in our country, and this kind of "green potash fertilizer", which is called the world shortage, is more popular in European countries.

China is one of the largest potash consumers in the world, accounting for about 2% of the world's potash consumption. From the consumption situation over the years, the total input of potash fertilizer increased from 386, tons in 198 to 7.2 million tons in 25, with an average annual consumption increase rate of 12%. Through hard work, the annual output of potash fertilizer in China has reached about 2.6 million tons (K2O), which can only meet about 3% of the domestic demand for potash fertilizer. About 5 million to 6 million tons of potash fertilizer need to be imported every year. The demand for potash fertilizer in China will still maintain an annual growth rate of 1 million to 1.5 million tons, but the output of potash fertilizer in China will only reach 3 million tons before 21, and the import volume will further increase.

seeing the continuous growth of potash import in China, international potash suppliers have formed a unanimous alliance, raising the price of potash fertilizer year by year. In 25, potash negotiations increased by 4 US dollars on the basis of RMB/ton in 1 yuan, 25 US dollars/ton in 26, 5 US dollars/ton in 27 and 4 US dollars/ton in 28. This directly led to a substantial increase in the retail price of potash fertilizer in China, which reached 2,8 yuan/ton by the end of 27, double that of three years ago, and continued to increase in 28. Solving the supply and stabilizing the price of potash fertilizer has become a thorny problem facing China.
