Title: An aspect on interlayer potassium of mica minerals in soils
Abstract: Abstract Cosiderable amount of mica minerals holding potassium in interlayer region occurs in clay fraction of various soils. In general, mica-type lattice structure of minerals has remained in certain case as forming interstratified mineral With 14A-spacing minerals such as vermiculite, montmorillonite and chlorite, and in other case they are existing as such. It is interesting and important to discuss the property of interlayer Potassium of mica minerals in soils comparing With that of minerals, geological origin, from a view point of potassium availability of soil. pedogenesis and weathering.
