That price increase was driven by strong demand (domestic and global), low fertilizer inventories, and very slow adjustments in production by the U.S. fertilizer industry. WebSulfur is the fourth major plant nutrients after nitrogen, phosphorus and potash and the form in which plants take up sulfur is SO 4 2−. Sulfur enters the soil system through microbial activities like mineralization, immobilization, and redox reactions. Microbes play an important role in releasing S from sulfide minerals to soil ecosystem.
