Affected by rising prices of raw materials such as urea, ammonium phosphate, and potash fertilizer, the prices of domestic compound fertilizers have risen steadily in the near future. Some manufacturers raised their factory prices by 30-80 yuan (t price, the same below), and reached a high of around 100 yuan. In particular, the increase in low-end prices is more obvious. At present, the factory price of 25% chlorine-based compound fertilizer is mostly 1280-1350 yuan, 30% of chlorine is 1550-1650 yuan, 40% of chlorine is 2180-2250 yuan, 45% of chlorine is 2340-2550 yuan, and 48% of chlorine is 2580- 2700 yuan. 40% sulfur 2350-2500 yuan, 45% sulfur 2600-2700 yuan, 48% sulfur 2800-2900 yuan.
