Langbeinite (0-0-22) is a granular organic sulfate of potash-magnesia. This unique source of minerals is a natural occurring source of Potassium, Magnesium, & Sulfur. Also referred to as K-Mag or Sul-Po-Mag, this crystalline/ granular mineral is water soluble providing these vital nutrients for immediate plant uptake. Langbeinite has a neutral pH & will not alter soil acidity, providing a long-lasting & readily available source of low-chloride potassium, magnesium & sulfur. This form of organic K-Mag is ideal for fruit & vegetable production in magnesium-deficient soils. The availability of organic Potassium helps plants deal with environmental stresses such as; compacted soils, dry soils / drought, cold soils & pest pressures. Langbeinite is registered & approved bu the Organic Materials Review Institute (OMRI) for use in organic production. Application Rates: Amending Soils: 1-2 lbs. per 100 sq ft Vegetables: Transplanting: 1 tbsp per planting site Side Dressing: 1 - 2 tbsp per plant Potted Plants / Soil Mix: 1 tbsp. per gallon of soil (mixed thoroughly) or add 1 - 2 lbs. per cubic yard of soil Trees & Shrubs: Transplanting: 1/4 - 1/2 cup per tree/ shrub planting site Side Dressing: Spread 1/2 - 1 lb per 1 trunk diameter. Spread throughout the plants drip line. Langbeinite is totally water soluble, but slow to dissolve because of the particle density. Use warm water to dilute faster GUARANTEED ANALYSIS POTASSIUM (K) 18.2% min. POTASSIUM (K20) 22.0% min. MAGNESIUM (Mg) 10.8% min. MAGNESIUM (MgO) 17.9% min. SULFUR (S) 22.0% min.
