Down To Earth™ Langbeinite 0-0-22 is a naturally mined crystalline mineral that supplies a water-soluble sulfate form of three vital plant nutrients: potassium, magnesium and sulfur. Its maximum chlorine content is less than 3%, minimizing the potential for fertilizer “burn.” It’s neutral pH does not alter soil activity.

DTE™ Langbeinite 0-0-22 is widely used on sensitive vegetables and fruit crops that require high fertilization rates but do not tolerate high levels of chlorine or soluble salts. This standard grade langbeinite has a typical SGN of 95 and is an excellent source of readily available sulfur, potassium and magnesium.
