A unique 3-in-1 combination of potassium, magnesium, and sulfur. K-Mag is a naturally occurring source of these three vital plant nutrients. Potassium is essential for high quality fruit, Magnesium is required for the synthesis of chlorophyll and Sulfur is needed for enzyme activation.
K-Mag fuels quality and yield by supplying a unique and perfectly balanced package of three essential nutrients — K, Mg and S — in the highly available water-soluble sulfate form:
21-22% POTASH (K2O) (18.2% POTASSIUM: K) — Potassium (K) is known as the "quality" nutrient. A good source of K, K-Mag promotes healthy root systems, increases plant vigor and resistance to disease and cold. K 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 (Mg) is the central component of chlorophyll, the pigment molecule responsible for absorbing sunlight during photosynthesis. Providing Mg and K 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 (S) helps build proteins in plants and is a key component of many unique traits. S puts the "green and leafy" into crops like spinach, while giving garlic and asparagus their distinctive flavors and improves the baking quality of wheat. S deficiencies are of particular concern as sulfur dioxide emission- reduction programs cause less S to be returned to the soil via the atmosphere. K-Mag provides an adequate supply of S for healthy crop production. Because it's in the sulfate form, it aids initial root growth — important in rapidly growing crops — and promotes seed production and vigorous plant growth.
Unlike many other magnesium sources, K-Mag is 100 percent water soluble. The solubility rate depends on its soluble chemical nature and its particle size. Refined and ground into various screen sizes, K-Mag goes to work immediately upon application provided there is enough soil moisture to support crop growth. Yet, K-Mag Granular dissolves slowly, resisting rapid leaching from the soil.
#2 Essentially chloride-free
K-Mag's maximum chloride content is less than 2.5 percent, minimizing the potential for fertilizer "burn." Thus, it is widely used on sensitive vegetable and fruit crops requiring high fertilizer rates, and on other crops that have a high K and Mg demand and do not tolerate chloride well.
#3 Provides balance of nutrients
The deficiency of any essential nutrient limits crop yields and crop quality — even when all other nutrients are present in adequate amounts. K-Mag supplies K, Mg and S 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. Producers can apply with confidence.
#5 Increases profit per acre
Crop producers throughout the world have reported extra profit per acre with K-Mag, especially on Mg- and S-deficient soils. Exact dollar benefits from K-Mag applications depend on crop and cropping methods, soil type, degree of soil nutrient deficiencies, previous cropping methods, and climatic conditions during the cropping year.
K-Mag can be used as part of a complete fertilizer for the crop, or applied directly to the soil. Check with your K-Mag dealer as to the best rates and application methods for your area.

If you want your vegetables to not only taste better but be healthier then adding rock dusts or trace minerals is important. Plants need more than just NPK and much of that is provided by rock dusts like basalt. What makes basalt special is that it contains many of these...
