Down To Earth All Natural Fertilizers #ad - Keep it real, keep it lightrail; Solidly made in the USA since 1986. Down to earth langbeinite 0-0-22 is a naturally mined crystalline mineral that supplies the water-soluble sulfate form of three vital plant nutrients: potassium, magnesium and sulfurs.

Potassium contributes strongly to overall plant health by regulating internal processes. Its maximum chlorine content is less than 3. 0 percent, minimizing the potential for fertilizer “burn, ” and its neutral pH does not alter soil activity. Potassium deficiencies lead to weak stalks and immature roots, leaving the plant susceptible to insects. Since potassium makes up part of the fluid of the plant, it is found throughout plant tissue, meaning plants need a strong source of potassium as they grow.
