“I applied 200 lbs/acre and realized a 9% increase in volume. I spent $21/acre which returned $28.80/acre. The feed quality of the alfalfa was also noticeably better. I am putting SUL4R-PLUS fertilizer on all my alfalfa crop this year.”

The most versatile and easy-to-use form of calcium and sulfur in the sulfate form, SUL4R-PLUS fertilizer is a proven producer.


SUL4R-PLUS pelletized calcium sulfate to perform. Proven to enhance yield on an extensive variety of crops, it also improves all soil types and is effective across a wide range of weather and humidity conditions.

SUL4R-PLUS fertilizer:

  • Is a premium calcium sulfate product that is manufactured to the highest degree of quality, ensuring a uniform pellet size and density that mixes better with inputs.
  • Blends better with NPK products than do ammonium sulfates, as ammonium sulfates are smaller and spread with less uniformity.
  • Provides even and complete coverage.
  • Is easy to handle, and has negligible dust.
  • Dissolves only where you want it to – in the soil – and it starts working almost immediately.
  • Is a superb carrier for micronutrients, according to third-party testing.
  • Delivers 17% sulfate and 21% calcium.

Why choose SUL4R-PLUS calcium sulfate over others?


SUL4R-PLUS pellets offer faster availability.

SUL4R-PLUS pellets dissolve on contact with water in soil solution, and are immediately available to the plant, unlike elemental sulfur, which can take up to a year for microbes to convert it into a plant-usable form. With a calcium content of 21 percent, SUL4R-PLUS calcium sulfate also doubles as a soil amendment.

“97% of our soil samples (were) coming back as low to deficient in sulfur….Since using SUL4R-PLUS fertilizer, our trials have shown a better stand and healthier soybean plant early on. In three of three comparisons, it has translated to an average of 4.25 bushels/acre yield advantage where we applied SUL4R-PLUS calcium sulfate.”

Ralph E. Hart, Crop Production Services

SUL4R-PLUS fertilizer is easy to apply.

Because the pellets are uniform in size, don’t absorb moisture from the air and are not dusty, SUL4R-PLUS pelletized calcium sulfate spreads evenly and completely. In fact, our revolutionary pellets are endorsed by New Leader®.

Sulfur is a necessary nutrient.

Today’s soils are low in sulfur, which makes crops weaker and later to mature. Crops need this essential element to reach their full yield potential.
