What is MST?

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.

What is MAP+MST?

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.

The Fourth Major Macronutrient

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.

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).
