  • What Are the Causes of High Potassium in Soil? Garden Guides

    Weathering of feldspar and mica in the soil causes the breakdown of potassium from fixed to non exchangeable to exchangeable (plant available) forms. Mica releases potassium more easily than feldspar. Although leaching of potassium is slow or minimal, regions where the climate is humid and wet tend to have lower amounts of plant available potassium.
