Sources of Potassium in Soil:
However, potassium is found in soils as both primary and secondary minerals. Various secondary clay minerals like illites (hydrous micas), Vermiculites, chlorites and interstratified minerals contribute a greater amount of potassium in soils

Sources of Potassium in Soil:
In addition to potassic fertilizers, the presence of potassium in soils originates from the disintegration and decomposition of potash bearing minerals. Some most important minerals are considered as the source of potassium namely potash feldspars (orthoclase and microcline, KAlSi3O8), muscovite [KAlSi3O10(OH)2], biotite [K (Mg, Fe]3 AlSi3O10 (OH)2] etc.
