EXPERIENCE SUPERIOR SULFUR RELEASE WITH SO4
Sulfur is an essential component of plant growth, with key processes relying on sulfur like chlorophyll formation and protein production. It is often considered the fourth major nutrient behind N, P
SO4 pelletized gypsum supplies a strong initial release of sulfur followed by a steady supply throughout the growing season, delivering the right of amount of sulfur to perfectly match plant needs for yield-maximizing plant growth. SO4 is mined and manufactured in northwest Iowa from one of the purest gypsum sources in the world. It is finely ground and pelletized to achieve a balance between solubility and pellet strength.
