Sulphur Delivers Consistent Yield Gains in Soybeans and Corn

When it comes to crop nutrition, sulphur is often overlooked, but multi-year data proves it’s a yield driver you can’t ignore.

Soybean Yield Response

Across 89 trials conducted over six years, applying Tiger-Sul sulfur increased soybean yields by 5 bushels per acre with Tiger XP® and by 3 bushels per acre with Tiger 90CR®.

Untreated Control: No sulphur or micronutrients (only N, P, K applied)

Sulphur Rate: Typically 25–30 lbs/A

Three extra bushels per acre may sound small, but it adds up quickly in today’s tight margins.

Corn Yield Response

Across 142 trials over 8 years, adding Tiger 90CR® or Tiger XP® sulphur increased corn yields by at least 6 bushels per acre compared to the grower standard.

Grower Standard: No sulphur or micronutrients (only N, P, K applied)

Sulphur Rate: Typically 30–40 lbs/A

Why Sulphur Matters

Sulphur improves nitrogen fixation, supports protein formation, and drives overall crop health. These trials confirm what agronomists have long suspected: sulphur isn’t optional, it’s essential.

If your fertility program doesn’t include sulphur, you could be leaving bushels in the field.
