Langbeinite Granule
Description
Our Langbeinite Granule is a high-quality source of not only Potassium but also Magnesium and Sulphur which work in a beautiful synergy with each other. The Granular form of our Langbeinite provides slow-release NPK with an approx ratio of 0-0-21 along with 20% Sulphur and 10% Magnesium. It provides the benefits that both Potassium Sulphate and Magnesium Sulphate offer, but in one handy to use amendment.
Langbeinite is derived from a specific dried up lake bed, millions of years old. It is not liberated from rocks through chemical means like many forms of Potassium Sulphate, existing naturally in this form.
While the Magnesium content of Langbeinite is generally a plus, there are situations where plants would prefer just the Potassium portion by itself, for a solution to this check out our Arcanite which is pure Potassium and Sulphur.
A little goes a long way with this amendment.
Application rates can range from as low as 1 to 2 Teaspoons (1/2 gram to 1 gram) per 5L of soil.
