    Good things come in threes

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

    Unique mineral composition for balanced crop nutrition

    With a unique blend of potassium, magnesium and sulfur in every granule, K-Mag allows for balanced crop nutrition across every acre.

    Low chloride for sensitive crops

    Certain crops are sensitive to high levels of chloride. Different from other potassium sources, K-Mag features a low salt index. Providing critical nutrition without damaging plants.

    pH neutral for greater control

    Different from traditional Mg or S sources, K-Mag’s unique make-up provides essential nutrients to crops without raising or lowering soil pH; regardless of application rate.

    Science driven. Research backed

    All over the globe, across a variety of crops and soil conditions—no other category of products have proven their performance like Mosaic crop nutrition and biosciences.

    Three formulas formed by nature

    To suit the specific nutritional needs of your operation, K-Mag is available in three different product offerings—Premium, Granular and Standard.

    K-Mag Premium offers the benefits and nutrients of K-Mag standard, but with greater uniformity of particle size—typically between UI 50 and 60—an excellent range for high-quality blends. Because of its granulated nature, K-Mag Premium is less abrasive, causing less wear and tear on blending and application equipment. It’s ideally sized for blending, with a typical SGN between 265 and 270.

    The standard formulation for K-Mag containing potassium, magnesium and sulfur with a typical SGN of 85 that works well in both direct application and as a key ingredient for many granulation facilities. With less than 2.5% chloride content, and a neutral pH that doesn’t contribute to soil acidity, K-Mag Standard is well-suited for use on a variety of sensitive, high-value crops.

    K-Mag Granular features the same benefits and nutrients as Standard and Premium, but is most typically utilized in bulk-blends Like K-Mag Premium, its granulated nature is less abrasive and reduces wear and tear on blending and application equipment.
