Potassium Boost: Langbeinite

A unique 3-in-1 combination of potassium, magnesium and sulfur, Langbeinite 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.

Ingredients: Potassium magnesium sulfate

OMRI Approved (Organic Materials Review Institute)

CDFA Approved (Registered Organic Input Material)

• Vegetable Gardens & Flower Beds: To prepare new gardens, apply 1-2 lbs per 100 square feet and thoroughly mix into the top 3″ of soil. To feed established plants, side dress 1-2 tablespoons per plant, depending on size of plant, once each month during the growing season.
• Containers: For new plantings, mix 1 tablespoon per gallon of soil and mix thoroughly OR add 1-2 lbs per cubic yard. For established plants, lightly mix 1-2 teaspoons per gallon into the soil surface once each month during the growing season.
• Trees & Shrubs: Spread ½ -1 lb per 1″ of trunk diameter around the base outwards to the drip line, mix into soil surface and water well. For new trees, prepare a transplant hole and mix ¼ – ½ cup with the backfill soil. Use amended soil to fill in around the new tree and water well.
• Row Crops/Acreage: Apply 200-500 lbs per acre depending on soil analysis, research data or specific crop needs.

• Improves Disease Resistance: Strengthens plant cell walls, enhancing resilience against diseases and pests. 
• Increase Crop Quality and Yield: Known to enhance fruit size, color, and taste, improving overall crop quality.
• pH Neutral: This naturally-occurring mineral does not alter soil pH to make it more alkaline or acidic.

Q: What is Langbeinite?

A: Langbeinite is a naturally occurring mineral and a unique 3-in-1 combination of potassium, magnesium, and sulfur—a vital source of essential nutrients for plants. It enhances plant health and growth by supporting strong root development, improving water efficiency, boosting photosynthesis, and enhancing crop quality and yield. Langbeinite is widely recognized for its role in organic gardening and is OMRI Approved and CDFA Approved.

Q: How do I know if I need this?

A: We recommend using our Epic Soil Testing Kit before adding any booster to your soil. This will help you know more about what your soil may be lacking in or need more of for optimal growing! Langbeinite is used to raise the potassium level in soils deficient in potassium.
