WHY AMMONIUM SULFATE?
CROP NUTRITION
AMMONIUM NITROGEN
CROP NUTRITION
Ammonium sulfate delivers sulfur and nitrogen in readily available forms, enhancing nutrient uptake, soil efficiency, and overall crop performance. It also improves the availability of phosphorus and key micronutrients in high pH soils by acidifying the root zone.
SULFATE SULFUR
AMMONIUM NITROGEN
CROP NUTRITION
Ammonium sulfate provides 100% sulfate sulfur—the only form plants can absorb. Unlike elemental sulfur, which takes months to convert in soil, sulfate sulfur is immediately available, ensuring crops get the sulfur they need
when they need it most.
AMMONIUM NITROGEN
AMMONIUM NITROGEN
AMMONIUM NITROGEN
Ammonium sulfate supplies 21% nitrogen in the efficient ammonium form, which is immediately available to plants and less prone to loss. It resists leaching, volatilization, and denitrification—making it ideal for surface application under reduced tillage conditions.
