Mica minerals contain 6–9 % K while alkali feldspars contain 3.5–12 % K and both represent major natural reserves for plant available K after weathering. Potassium uptake by plants reduces its concentration in rhizosphere in the roots vicinity which ultimately stimulates the K-release from the minerals (Kuchenbuch and Jungk 1984).Web
