K-Mag® Potassium Fertilizer Celebrates 75 Years

December 19, 2014   |   ShareThis

This month, The Mosaic Company celebrates the 75th anniversary of K-Mag®, a unique source of properly balanced potassium (K), magnesium (Mg) and sulfur (S) in a highly available water-soluble form.

While agriculture has experienced a bounty of change, K-Mag has remained a constant source of crop nutrition that farmers can rely on. Since 1939, K-Mag has been mined and processed in Carlsbad, New Mexico, from an ancient sea far beneath the Guadalupe Mountains. This ancient sea is home to the world’s largest and purest deposits of langbeinite ore, a potassium magnesium sulfate mineral.

In the time since, K-Mag has experienced several different looks, but its quality today remains consistent. Mosaic’s K-Mag formulation continues to blend well with other fertilizer products, delivering a balanced ratio of potassium, magnesium and sulfur. Flip through our interactive K-Mag logo history.

K-Mag History Highlights:

  • 1943: The owner of the plant was presented with the Army-Navy “E” Award for its outstanding contribution to the war effort, as the Carlsbad area supplied the majority of the nation’s potash requirements.
  • 1968: The Carlsbad mine was the sole location in the world for a plant that could separate the mixed ore bed into sylvite and lang components.
  • 1998: The new K-Mag plant was commissioned and now supplies numerous locations with the fertilizer.
  • 2014: The Mosaic Carlsbad mine transitions to exclusive production of the K-Mag product line.
