What is K-Mag®?
Found at only a few places in the world, K-Mag is an uncommon mineral known as langbeinite. Its potent combination of potassium, magnesium and sulfur features a unique natural chemistry that make it safer and more effective for sensitive and high-yield crop systems.
What is the percentage of potassium in K Mag fertilizer?
K-Mag fertilizer has an analysis of 21 to 22 percent potash, 10 to 11 percent magnesium and 21 to 22 percent sulfur. K-Mag, or potassium magnesium sulfate, is 100 percent water soluble and will work immediately upon application provided there is enough soil moisture to support crop growth.
Can you use K-Mag fertilizer on palm trees?
RECOMMENDED USE: for palms, trees, shrubs, turf, ornamental and fruit-bearing trees. We recommend using it in conjunction with our 8-2-12 granular fertilizer for palms that are deficient in potassium and/or magnesium. Tree Saver is now offering this 20lb. bag of 0-0-22 Premium K-Mag commercial grade fertilizer.
Why use K-Mag® for soil pH?
Most sources of sulfur tend to lower soil pH, whereas most magnesium sources will raise it. K-Mag, however, has a natural chemical composition that maintains K, Mg and S in immediately-available forms without modifying soil pH. K-Mag gives growers the flexibility to apply as much or as little as needed to meet crop nutritional needs.
