Langbeinite 0-0-22 Fertilizer (5 lb box)Langbeinite is a popular fertilizer, especially where several plant nutrients are needed to provide adequate nutrition. It has an advantage of having potassium, magnesium, and sulfur all contained within a single particle, which helps provide a uniform distribution of nutrients when it is spread in the field. Its neutral pH does not alter soil acidity and its maximum chlorine content is less than 3. 0%, minimizing potential for fertilizer "burn".
