PriceSeek analysis of potassium nitrate, with a long-short score of -1: Zhongpeng Company's ex-factory price for agricultural-grade potassium nitrate decreased by 50 yuan per ton from the previous quotation date to 4,200 yuan per ton, reflecting a potential increase in market supply or weak demand, leading to downward pressure on spot prices. Although the annual production capacity of 50,000 tons indicates stable production, the declining price trend suggests a short-term imbalance between supply and demand in the market, which may affect downstream purchasing behavior and intensify bearish sentiment in the spot market.
