## Overview

Langbeinite (Sulfate of Potash Magnesia) is an organic, naturally mined fertilizer with an NPK of 0-0-22, delivering essential potassium, magnesium, and sulfur in a plant-safe, low-chlorine formula. Ideal for sensitive vegetables and fruit crops, it promotes stronger stalks, healthier roots, and abundant fruit production without risking fertilizer burn.

## Description

Langbeinite Fertilizer (NPK of 0-0-22) (AKA Sulfate of Potash Magnesia K-MAG) is a naturally mined crystalline mineral approved for Organic use, that supplies the water-soluble sulfate form of three vital plant nutrients: potassium, magnesium and sulfurs. It’s maximum chlorine content is less than 3.0 percent, minimizing the potential for fertilizer “burn,” and it’s neutral pH does not alter soil activity. Potassium contributes strongly to overall plant health by regulating internal processes. Since potassium makes up part of the fluid of the plant, it is found throughout plant tissue, meaning plants need a strong source of potassium as they grow. Potassium deficiencies lead to weak stalks and immature roots, leaving the plant susceptible to insects. Langbeinite 0-0-22 is widely used on sensitive vegetables and fruit crops that require high fertilization rates but do not tolerate high levels of chlorine or soluble salts. This standard grade langbeinite has a typical SGN of 95 and is an excellent source of readily available sulfur, potassium and magnesium.

Review: Great fertilizer - This is the third year that I've used this product. It's a good way to get potassium into depleted soil.
Review: A GAME CHANGER that has given me more fruit than I know what to do with! - The main reason that I purchased this was because I heard it was excellent for stimulating the growth of bananas on my trees. I have had banana trees for three years, watering frequently, and even using 10-10-10 fertilizer, but with no success in growing bananas. So I decided to give us a shot, hoping for at least a nice thick bunch of bananas. Much to my surprise, a nice bunch grew on both of my trees. Over the months, I watered the trees and continued to add this potassium-rich Langbeinite to ensure that the bananas grew thick and hardy. Much to my amazement, three more bunches of bananas grew on adjacent trees and now I have more than I know what to do with! Not only is this outstanding to stimulate fruit production on banana trees and various other fruit trees that I have in my yard, but I use this on my palm trees and the fronds are thick, beautiful, and luscious.

### ⭐⭐⭐⭐⭐ Great fertilizer

### ⭐⭐⭐⭐⭐ A GAME CHANGER that has given me more fruit than I know what to do with!
*by J***. on January 31, 2026*

### ⭐⭐⭐⭐⭐ Got fabulous results...it is worth a try
*by C***. on September 12, 2021*

Well, I didn't expect to get the stunning crops from my apples, figs and persimmon espaliers - that are literally crammed into a 400 sq' allotment garden - but I did. The only thing I changed from the low nitrogen 5 3 1 GroPower regimen I've always used was adding Langbeinite by the handful three times throughout the dormant and leafing season. It would be pretty expensive to use on my small citrus grove but I suspect those trees, also planted pretty close, would benefit, too. The results were slow to show but this product made my sad, sad roses look like champs, my struggling newer espaliers produce wonderful fruit, and my established apple espaliers had amazing crops in both size of fruit and quantity and I was blown away. I have to say that an associate at an Armstrong Garden Center suggested it and I was skeptical and then I figured I had nothing to lose.
