Before the Clean Air Act, growers never had to think twice about sulfur. Rain brought it back to the soil naturally, and crops got what they needed without much effort.

But times have changed. Cleaner air is great for our communities, it just means sulfur isn’t being replenished the way it used to be. And with today’s push for higher yields, sulfur has become a nutrient we now have to plan for on purpose.

The payoff is worth it: sulfur helps nitrogen work harder, supports stronger plant health, and plays a big role in getting crops to reach their full potential.

That’s why we’re focused not only on delivering high‑quality sulfur fertilizers, but also on helping growers understand how the right sulfur strategy can drive better yields and better profitability. 🌾💰

Stronger nutrition. Stronger crops. Stronger returns. ✨

Unlock the power of sulfur — and unlock the true potential of your fields.

🐝 Safety in action—sometimes it even involves saving the bees.

When a hive appeared overnight on equipment at our Hanford plant, the team made a values-driven choice.

They stopped, assessed the risk, and worked with Kingsburg Honey to safely relocate the hive—queen included.

It’s a powerful reminder:
Safety, responsibility, and environmental stewardship go hand in hand.

Growers have many sulfur‑based fertilizer options, and understanding the right fit is key to maximizing crop performance.

That’s why our Learning Center in Dinuba, California tests new ideas, evaluates formulations, and explores the full potential of thiosulfates in real‑world conditions.

Better research leads to better recommendations, helping growers boost nutrient efficiency and get the most from precise sulfur management.
