The Soil Potassium Cycle – An Introduction to SOIL

04052017· The Potassium Cycle: Potassium comes from primary minerals in soil like micas and potassium feldspar These minerals slowly weather and eventually the potassium becomes more and more available to be held in soil solution or taken up by plant roots Once plants take up a ton of potassium it is leached from leaves to soil by rainfall This and animal urine is how it gets returned toSummaryFinegrained homogeneous powder samples of thirteen trioctahedral micas, mostly intermediate members of the phlogopite – annite solid solution series, and samples close to the phlogopite, fluorphlogopite and tetraferriphlogopite end members have been examined at the potassium Kedge by Xray absorption fine structure spectroscopy The interlayer K+ cation is in aPotassium coordination in trioctahedral micas investigatedThe rate of release of K and structural cations from three micas (biotite, phlogopite, and muscovite) was measured in twoparticle size ranges (5 – 20µm and 20 – 50µm), in dilute electrolyte solutions (0001N), and at pH 30 and 70The rate of K release from phlogopite and biotite was similar to the rate of release of structural cations under acidic conditions and significantly higherRelease Rate of Potassium and Structural Cations from
