Smart Nutrition™ MAP+MST® – How it Works

Smart Nutrition™ MAP+MST® is the latest, most efficient system for delivering sulfur and phosphate to your crops when they need it most. This new fertilizer technology is a great choice for farmers wanting to add sulfur into their nutrient management programs. As with any new product, you’re probably asking yourself how this fertilizer technology works. Continue reading to learn how Smart Nutrition MAP+MST works.

Smart Nutrition MAP+MST is a homogeneous granular fertilizer that integrates the micronized elemental sulfur directly in the manufacturing of Mono-Ammonium Phosphate (MAP) granules. A homogenous mixture made into a granule means each granule contains nearly identical amounts of both MAP and MST, providing consistent nutrient delivery across your entire field. Compared to other multi-nutrient fertilizers, the high phosphorus and sulfur nutrient density means overall lower fertilizer volumes are needed to meet nutrient recommendations.

The micronized sulfur technology (MST) in Smart Nutrition MAP+MST is a patented technology, used under license by Sulvaris Inc., where the elemental sulfur source has been micronized and is the smallest particle size in the industry. At an average of 15 micron, the smaller particle size allows for quicker elemental sulfur oxidation.

Elemental sulfur must be oxidized to sulfate before the plant can utilize it. Sulfur oxidation rates are dependent on several key factors:

Environmental and Soil Factors:

  • microbial presence
  • soil temperature, moisture, aeration, and soil pH

Fertilizer Factors:

  • sulfur particle size
  • sulfur particle distribution

The small particle size of the MST increases soil-to-fertilizer surface area contact which increases sulfur oxidation rates. As the surface area of elemental sulfur increases, so does uptake into the plant. The nutrient density of Smart Nutition MAP+MST allows for fertilizer applications of nitrogen, phosphorus, and sulfur.

Additional Benefits of Smart Nutrition MAP+MST:

  • Decreased risk of sulfur leaching
  • Slow release keeps sulfur available throughout the growing season
  • Reduced salt index improves seedling development delivering seed row safety
  • Safe to handle and store
  • High analysis for decreased application rates
  • Enhanced product combining P+S
