Down to Earth Langbeinite 0-0-22 | 5lb - OMRI Listed - (Case of 6)

Langbeinite 0-0-22 Providing Potassium, Magnesium, and Sulfur for Plants (5lb)

Down to Earth Langbeinite 0-0-22 is an OMRI Listed naturally occurring mineral providing a unique 3-in-1 combination of potassium, magnesium, and sulfur. Potassium is essential for fruit quality, magnesium is required for chlorophyll synthesis, and sulfur is needed for enzyme activation. Langbeinite delivers all three of these vital plant nutrients in a single, naturally occurring source.

The 5lb size (Case of 6) is practical for home gardeners and small farms who apply langbeinite to vegetable gardens, fruit trees, or root crops throughout the season.

Key Features & Benefits

• 3-in-1 Potassium, Magnesium, and Sulfur — Provides three essential plant nutrients in a single naturally occurring mineral source.
• OMRI Listed — Approved for certified organic production.
• Supports Fruit Quality — Potassium is essential for high-quality fruit production.
• Required for Chlorophyll Synthesis — Magnesium plays a central role in chlorophyll molecule formation and photosynthesis.
• Enzyme Activation — Sulfur is needed for enzyme activation and protein synthesis in plants.

Who Should Use Down to Earth Langbeinite 0-0-22

Langbeinite 0-0-22 suits organic farmers, market gardeners, and home growers who need to supplement potassium, magnesium, and sulfur together — particularly those growing high-potassium-demand crops such as fruiting vegetables, root crops, and fruit trees. It is also valuable when soil tests indicate deficiencies in two or more of these nutrients.

Potassium, Magnesium, and Sulfur in Plant Nutrition

Potassium, magnesium, and sulfur are all essential plant macronutrients — each playing distinct but important roles. Potassium supports fruit quality, water regulation, and overall plant vigor. Magnesium sits at the center of every chlorophyll molecule and is required for photosynthesis and nutrient mobility within the plant. Sulfur is needed for enzyme activation, protein synthesis, and the production of certain amino acids. Langbeinite is a naturally occurring mineral that provides all three in a single source, making it particularly efficient when multiple nutrient needs coincide.

Frequently Asked Questions

What makes Langbeinite a 3-in-1 fertilizer?

Langbeinite is a naturally occurring mineral (potassium magnesium sulfate) that contains potassium, magnesium, and sulfur in its chemical structure. Applying Langbeinite supplies all three nutrients in a single application.

Is Down to Earth Langbeinite 0-0-22 OMRI Listed?

Yes. It is OMRI Listed and appropriate for certified organic production.

What crops benefit most from Langbeinite?

Crops with high potassium demands benefit particularly from Langbeinite, including fruiting vegetables, root vegetables, and fruit trees. It is also valuable when soil tests show deficiencies in potassium, magnesium, or sulfur simultaneously.

Does Langbeinite affect soil pH?

Langbeinite is generally considered neutral to slightly acidic in its effect on soil pH, making it suitable for a broad range of soils without the pH-raising effect associated with lime-based amendments.

Why is magnesium important for plant growth?

Magnesium sits at the center of every chlorophyll molecule and is essential for photosynthesis. It is also involved in phosphate metabolism and the transport of nutrients within the plant. Magnesium deficiency commonly appears as interveinal yellowing on older leaves.
