Potassium, magnesium and sulfur in one

K-Mag is a naturally occurring mineral that supplies potassium, magnesium and sulfur in a highly available, water-soluble sulfate form.

Key things we want you to know

  • Analysis: 21 to 22% potash, 10.5 to 10.8% magnesium, 21 to 22% sulfur.
  • Why it matters: potassium for fruit quality, magnesium for chlorophyll, sulfur for enzymes.
  • Sizes: 12, 25 and 50 lb.

Benefits & Features

  1. Resists leaching: K-Mag is 100 percent water soluble, so it goes to work as soon as there is enough soil moisture to support crop growth. K-Mag Granular dissolves slowly, resisting rapid leaching from the soil.
  2. Essentially chloride-free: Maximum chloride content is less than 2.5 percent, minimizing the potential for fertilizer "burn." It is widely used on sensitive vegetable and fruit crops and other crops that do not tolerate chloride well.
  3. Provides a balance of nutrients: K-Mag supplies potassium, magnesium and sulfur in a balanced proportion that fits the nutrient needs of many crops.
  4. Does not change soil pH: Regardless of application rate, K-Mag does not change soil pH because it is a neutral salt.
  5. Increases profit per acre: Crop producers around the world have reported extra profit per acre with K-Mag, especially on magnesium- and sulfur-deficient soils. Results depend on crop, soil type and growing conditions.

K-Mag can be used as part of a complete fertilizer for the crop or applied directly to the soil.

Ingredients

  • 21-22% Potash (K₂O), 18.2% Potassium (K): Known as the "quality" nutrient. A good source of potassium, K-Mag promotes healthy root systems and increases plant vigor and resistance to disease and cold. Potassium is also essential in sugar and starch formation and the movement of nutrients through plants.
  • 10.5-10.8% Magnesium (Mg), 18% Magnesia (MgO): Magnesium is the central component of chlorophyll, the pigment molecule that absorbs sunlight during photosynthesis. Providing magnesium and potassium in the proper balance, K-Mag helps increase plant strength and builds resistance to winter kill, drying, insect attack and spray damage.
  • 21-22% Sulfur (S), 67% Sulfate (SO₄): Sulfur helps build proteins in plants and is a key component of many unique traits. It puts the "green and leafy" into crops like spinach, gives garlic and asparagus their distinctive flavors, and improves the baking quality of wheat. Because it is in the sulfate form, it aids initial root growth and promotes seed production and vigorous plant growth.

Helping me grow healthful food in a healthful way

K-Mag is the right product for my needs. Being pH neutral helps to provide balanced nutrition without the need to adjust for a change in acidity. It's simple. Application is easy. My crops are growing nicely, naturally, organically. We'll all benefit from great food grown in a great way. Pardon me: I want to go back outside and admire crops.

Product is a little pricy

Experience is good…my only comment is I paid 1.70 a pound, you shipped it in a “if it fits it shops” USPS container.. a friend informed me of our local CO-OP selling it at .40 cents a pound, in bulk.. Comtacted the CO-OP and they were willing to see me this product in 100 pound increments. I am not opposed to anyone making a little money for their business but I can imagine you all rolling around in the floor laughing that someone was stupid enough to buy your 35 pounds for 60.00 dollars…shame on me

Thank you for taking the time to review the product. I wanted to address some of your concerns regarding the cost of the product. We do encourage folks to look locally first for amendments, as that is always the most sustainable and usually the most affordable option. Secondly, our K-Mag is certified organic, which my not be the case with your local option. Lastly, while we do offer free shipping, it has to be incorporated into the cost of the product which does raise the overall price per lb. We work very hard to offer competitive pricing regarding online options and appreciate your support of our small business.
