Urea prices rise and fall and local fertilizers delay
Domestic urea prices are mixed. Local distributors in northern Fujian, southern Henan, and Jilin began to stock up, and the sales of urea slightly improved. Therefore, the factory price of individual local manufacturers increased slightly by RMB 10/ton. However, most markets in Hebei, Shandong, Liaoning, and Heilongjiang have not started yet, and the main trend is still weak. Some manufacturers' prices are slightly reduced by RMB 10/ton, and factory prices in most factories in and around Shandong remain at RMB 1,550/ton. The above-mentioned, low-end transactions were explored in the range of 1510-1530 yuan/ton. Currently Hubei, Hunan manufacturers offer 1,600-16,060 yuan / ton range, today's individual manufacturers in Hunan offer down 50 yuan / ton. It is understood that the harvesting of winter wheat in Shandong, Hebei, Henan and other regions will be postponed until the 10th of this month, and the sowing of summer corn will also be postponed until the middle of this month. Therefore, the top-dressing season may also be postponed. It is expected that urea sales will be made later this month. The situation may turn for the better. In the short term, the main trend will continue to remain slightly oscillating, and even if the sales turn for the better, the rebound will not be very big.
