Know before you buy
Langbeinite is a naturally occurring mineral that provides a unique three-in-one nutrient profile: potassium, magnesium, and sulfur. Unlike many synthetic fertilizers that only supply potassium, this mineral offers these nutrients in a water-soluble sulfate form that plants can easily absorb.
Yes. Because this product has a very low chlorine content—a maximum of 3%—it is an excellent choice for salt-sensitive crops like potatoes, strawberries, and various nursery plants that might otherwise suffer from fertilizer burn.
No, this product has a neutral pH. It is designed to provide essential nutrients without significantly altering the acidity or alkalinity of your soil, making it a safe addition to most garden beds.
You can use it for both. Because it is granular and water-soluble, it works well when mixed into potting soil for containers or applied as a side dressing for plants already in the ground.
The combination of potassium and magnesium is essential for plant metabolic processes, including sugar transport and enzyme activation. Providing these nutrients helps improve the overall quality, flavor, and size of your fruits and vegetables.
Yes, Down To Earth Langbeinite is OMRI-Listed, meaning it meets the standards required for use in organic production systems.
