Down to Earth Langbeinite 0-0-22 | 1lb - OMRI Listed - (Case of 6)

Naturally Occurring 3-in-1 Potassium, Magnesium, and Sulfur Mineral, 1lb

Correcting a soil test that shows low potassium, magnesium, and sulfur all at once usually means reaching for three separate products, unless the deficiency happens to line up with a mineral that supplies all three at once. Down To Earth Langbeinite 0-0-22 is that mineral — potassium magnesium sulfate occurring naturally, mined and packaged without further processing into separate nutrient streams.

The 1lb size, sold as a case of six, is convenient for home gardeners and small-scale growers applying Langbeinite in targeted amounts to specific crops or garden beds.

Key Features & Benefits

• 3-in-1 potassium, magnesium, and sulfur — provides three essential plant nutrients from a single naturally occurring mineral source.
• OMRI Listed — approved for certified organic production.
• Supports fruit quality — potassium plays a direct role in fruit quality and overall plant vigor.
• Central to chlorophyll synthesis — magnesium sits at the core of every chlorophyll molecule, supporting photosynthesis.

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

This fits organic farmers, market gardeners, and home growers who need to supplement potassium, magnesium, and sulfur together, particularly when a soil test shows two or more of these nutrients running low at once.

Frequently Asked Questions

How does Langbeinite work as 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 it supplies all three nutrients in a single application rather than three separate products.

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

Yes, this Langbeinite is OMRI Listed, making it suitable for certified organic growing operations. As a naturally mined mineral, it fits organic programs without further chemical processing.

What crops benefit most from Langbeinite?

Crops with high potassium demand benefit particularly, including fruiting vegetables, root vegetables, and fruit trees. It's also useful when a soil test shows deficiencies in potassium, magnesium, or sulfur at the same time.

Does Langbeinite affect soil pH?

It's generally considered neutral to slightly acidic in its effect on soil pH. That makes it suitable across a broad range of soils, unlike lime-based amendments that raise pH as a side effect.

Why is magnesium important for plant growth?

Magnesium sits at the center of every chlorophyll molecule and is essential for photosynthesis, and it's also involved in phosphate metabolism and nutrient transport within the plant. Magnesium deficiency commonly shows up as interveinal yellowing on older leaves.
