Langbeinite is a popular fertilizer, especially where several nutrients are needed to provide adequate plant nutrition. It has an advantage of having K, Mg, and S all contained within a single particle, which helps provide a uniform distribution of nutrients when it is spread in the field.

Its neutral pH does not alter soil acidity and its maximum chlorine content is less than 3.0%, minimizing potential for fertilizer "burn".

Langbeinite is totally water soluble, but is slower to dissolve than some other common K fertilizers because the particles are denser than other K sources. Therefore, it is not suitable for dissolving and application through irrigation systems unless finely ground.

  • Guaranteed analysis: Soluble potash–22%; Sulfur–22%; Magnesium–10.8%
  • It has a neutral pH, and does not contribute to soil acidity or alkalinity. This differs from other common sources of Mg (such as dolomite) which will increase soil pH and from elemental S or ammonium sulfate which will lower the soil pH.
  • Low in chlorides
  • Derived from sulfate of potash-magnesia
