Smart Nutrition™ MAP+MST® delivers high-powered performance in a small particle size. Featuring both sulfur and phosphate, Smart Nutrition MAP+MST is engineered to slowly release sulfur throughout the growing season.
Empower your soil with key benefits including:
Micronized Sulfur Technology (MST) is a patented technology where the elemental sulfur source has been micronized, resulting in an average particle size of 15 micron. The small particle size allows for quicker elemental sulfur oxidation and increased surface area.
MAP+MST integrates the micronized elemental sulfur directly in the manufacturing of Mono-Ammonium Phosphate (MAP) granules. This creates a uniform distribution of MST in each granule, providing maximum soil to fertilizer contact and an increased oxidation rate for quick crop use.

Sulfur is an overlooked nutrient in crop nutrition, but it shouldn’t be. Behind NPK, it’s often referred to as the fourth major macronutrient and plays a vital role in plant development. Smart Nutrition™ MAP+MST® is a great option for adding that needed sulfur to your soil and crops.

Smart Nutrition™ MAP+MST® combines sulfur and phosphorus in each granule, enhancing the effectiveness of both. This synergy promotes balanced nutrition and boosts growth, health, and yield for improved agricultural productivity.

Smart Nutrition™ MAP+MST® is easy to handle and store, making it easy to add to your operation. Its homogeneous composition also makes it ideal for bulk blending and provides consistent delivery at decreased application rates.

The homogeneous distribution of micronized sulfur within the granules ensures consistent delivery and decreased application rates. This consistency means more predictable results and efficient use of fertilizer across your fields.

Grower Question
“How is it Smart Nutrition MAP+MST micronized?”
Mackenzie, Alberta
Agronomist Answers
Micronized Sulphur Technology (MST) is a proprietary patented technology from Sulvaris. The micronized sulfur is added into our monoammonium phosphate production process in White Springs, FL. The final product is homogenized meaning each granule has nitrogen, phosphate, and sulfur (9-43-0-16S).
