Down to Earth Langbeinite

Langbeinite is a naturally occurring mineral that provides a concentrated, water-soluble source of potassium, magnesium, and sulfur. It is an excellent choice for correcting specific nutrient deficiencies or boosting overall plant vigor without adding nitrogen or phosphorus.

Because it contains no nitrogen or phosphorus, this product is best used as a targeted supplement rather than a complete fertilizer. Apply it when your soil test indicates a need for potassium or magnesium, or during the fruiting and flowering stages of your plants to support development.

Yes, this product is OMRI listed, meaning it is approved for use in certified organic gardening. It is a natural mineral source that integrates well into organic soil management programs.

The powder form is highly versatile and can be mixed directly into your soil or soilless potting mixes before planting. Because it is finely ground, it breaks down relatively quickly, making the nutrients available to plant roots more efficiently than coarser mineral amendments.

Langbeinite is considered pH-neutral, so it will not significantly raise or lower your soil's acidity or alkalinity. It is a safe, reliable way to add essential nutrients without disrupting your existing soil chemistry.
