Mica is a mineral name given to a group of minerals that are physically and chemically similar They are all silicate minerals known as sheet silicates because they form in distinct layers Micas are fairly light and relatively soft and the sheets and flakes of mica are flexible Mica is heat-resistant and does not conduct electricity
Removal of K can be very high in forage or silage crops where the entire plant is harvested With these crops relatively high rates of potassium fertilizer are required to replace the potassium removed - providing soil tests indicate a need If only grain is harvested much less K is removed by the crop Forms of Soil Potassium
Potassium Chloride KCl • Most commonly used source sometimes called muriate of potassium • Analysis range from 60 to 63 and 45 to 46 chloride • Color ranges from deep red to pink to white • Red potash made by grinding ore suspended in water and skimmed off iron adheres giving a red color • White potash made by dissolving under a not brine under pressure

Potassium was removed from 5 to 20-μ size fractions of two phlogopites by treatment with sodium tetraphenylboron and replaced with various exchange ions The b-dimension of the mica increased with K removal which suggests that the K ion in phlogopite acts to constrain b This being the case the K—O bond in phlogopite must be lengthened
