MTS=™ Magnesium Thiosulfate

A Reliable Source of Magnesium & Sulfur for Modern Crop Nutrition

MTS=™ (Magnesium Thiosulfate or MgSO3) is a premium liquid fertilizer designed to deliver two essential nutrients—magnesium (Mg) and sulfur (S)—in a highly plant‑available form. MTS=™ is engineered to support balanced fertility programs across a range of soil textures and cropping systems.

As one of the only dedicated suppliers of high-quality magnesium thiosulfate, our strong production capacity and reliable logistics provides consistent supply availability for ag retailers, wholesalers, and distribution partners.

Why Magnesium Thiosulfate

Why Magnesium Thiosulfate?

Magnesium and sulfur are core elements of chlorophyll formation, enzyme activation, and protein synthesis. MTS=™ delivers both nutrients in a fully soluble, easily-blended liquid form that supports:

  • Improved nutrient uptake
  • Deficiency correction
  • Soil conditioning
  • Reduced nutrient runoff
  • Foliage burn prevention

The thiosulfate form offers a gradual oxidation pattern, helping minimize nutrient tie-up and supporting steady uptake during critical growth stages. View Product

 

Where Does MTS=™ Perform Best?

Magnesium thiosulfate is especially effective in lighter, low‑CEC soils, where magnesium is more prone to leaching and sulfur availability can fluctuate. Ideal soil types include:

Sandy Loams

West Coast: Known for high-value specialty and commodity crops, states like California, Oregon, and Washington often employ intensive cropping systems that require precise nutrient management. Magnesium and sulfur supplementation can be necessary for your customers’ success.

Southwest: Warm, arid climates of the Southwest rely on irrigation agriculture and require fertigation supplementation of key nutrients like magnesium and sulfur.

Midwest: While the Midwest is known for its nutrient-rich soils growing row crops like corn, soybeans, wheat, and forages, certain regions with lighter, sandier soils may have additional magnesium and sulfur needs. Potatoes, vine products like melons, and sugar beets are examples of crops in the Midwest that can benefit from these added nutrients.

South: Hosting a broad mix of row crops like cotton, specialty crops like rice and peanuts, and pastures, magnesium and sulfur needs can vary. Weathered and acidic soils may experience magnesium deficiencies, while others like cotton can benefit from magnesium thiosulfate for fiber development.

Less suited: Very heavy, high‑CEC soils or regions with naturally high magnesium levels may not realize the same efficiency benefits. Explore other fertilizer options for these conditions.

 

Key Crops for Magnesium Thiosulfate

MTS=™ supports a wide range of cropping systems. Retailers serving the following markets can position magnesium thiosulfate as a core part of their nutrient portfolio:

Magnesium Thiosulfate Corn

Row Crops

  • Corn: Enhances chlorophyll formation and foliar color
  • Soybeans: Supports protein development and pod fill
  • Cotton: Improves fiber development and sulfur-driven nitrogen efficiency
  • Wheat & Small Grains: Sustains sulfur availability throughout tillering and grain fill

Magnesium Thiosulfate Potatoes

Specialty Crops

  • Potatoes: Highly responsive to magnesium and sulfur for tuber quality and yield
  • Almonds, Walnuts & Tree Nuts: Supports nut fill, kernel quality, and sustained canopy health
  • Vegetables (Tomatoes, Onions, Brassicas, Peppers): Promotes uniform growth and improves nutrient-density
  • Fruit Crops (Berries, Grapes): Enhances color development and supports consistent fruit set

 

 

Magnesium Thiosulfate Application Methods

 

MTS= Application Method Soil

Soil Application (Pre‑Plant or Side‑Dress)

MTS=™ is most commonly applied directly to the soil (broadcast, banded, or injected) before planting or early in the season. This places magnesium and sulfur in the root zone when crops need them most. This method is ideal for row crops and forage systems.

MTS= Application Method Fertigation

Fertigation

In irrigated crops (orchards, vineyards, potatoes, and vegetables) MTS=™ can be delivered through drip or sprinkler systems for even distribution. This method ensures nutrients reach the active root zone efficiently without extra field passes.

MTS= Application Method Foliar

Foliar Application

MTS=™ can be used in some foliar programs at low rates to address in‑season deficiencies, but it is not the primary or preferred way to deliver magnesium and sulfur. Adequate dilution is required to avoid leaf burn.
