How to Reduce Potassium Levels in Soil | Hunker
A bit too much potassium in garden soil is not typically a problem for most plants, but in high excess, potassium can cause problems. One major problem is the inhibition of calcium. Common causes of exorbitant potassium levels include over-fertilizing and a large number of rocks and minerals in the soil.
AGR-11 Potassium in Kentucky Soils
Native Potassium -- This is the potassium that was in the parent material (rocks) from which the soil was formed. The potassium in the parent material is contained primarily in two minerals, mica and feldspar. Where the parent material has a relatively high content of mica, potassium is released to an available form at a more rapid rate.
