K-Mag contains a natural balance of potassium, magnesium, and sulfur in each granule ensuring that nutrients are spread uniformly across the field for maximum availability for every plant.

Product Description

K-Mag® is a potassium fertilizer, also containing magnesium and sulfur, with a long legacy of proven performance and typically utilized in bulk-blends.

Analysis: 0 – 0 – 22 – 11% Mg – 22% S

Properties: Granule, water soluble

Application Methods

  • Broadcast (dry surface application)


  • With a low 2.5% chloride content, K-Mag minimizes the potential for fertilizer burn
  • Widely used on sensitive vegetable and fruit crops requiring high fertilizer rates. It is also used on crops that demand high potassium and magnesium inputs, yet are sensitive to chloride, such as tobacco
  • Neutral in pH, K-Mag does not contribute to additional soil acidity. It is in a water soluble sulfate form making it a feeding site of readily available nutrients for crops. And, because of its crystalline nature, K-Mag GRANULAR dissolves gradually throughout the growing season, providing a season-long source of nutrients.
