Feldspar. Feldspar is a milled crystalline anhydrous sodium potassium aluminium silie. It has a high dry brightness, high hardness, good heat stability, is inert and is easy to disperse. The main appliion for Feldspar is as a general filler in selflevelling floor screeds, paints, polymers, adhesives, polishes and rubbing compounds.

· Rock powders are lowcost potential sources of most of the nutrients required by higher plants for growth and development. However, slow dissolution rates of minerals represent an obstacle to the widespread use of rock powders in agriculture. Rhizosphere processes and biological weathering may further enhance mineral dissolution since the interaction between .
All these sources give potash (97% potassium chloride) with a 60% K2O equivalent for fertilizer use. A chemicalgrade product can be obtained to a purity of % potassium chloride. Almost all potash produced is potassium chloride. Potash is used mainly as fertilizer (88%) with a small amount (12%) used in chemical manufacture. []

· B. cereus YN917 was grown on LB medium at 28°C, 180 rpm for 12 h, and the culture was diluted by sterile distilled water and adjusted to an optical density OD 600 = 1 before inoculation. Magnaporthe oryzae was previously isolated and preserved by our laboratory, and maintained in potato dextrose agar (PDA) plates.
Elemental potassium is a soft silverywhite alkali metal that oxidizes rapidly in air and reacts vigorously with water, generating sufficient heat to ignite hydrogen emitted in the reaction and burning with a lilaccolored flame. It is found dissolved in sea water (which is % potassium by weight), and is part of many minerals.
· Potassium uptake values for the final harvests ranged from to cmol K/kg and tissue %K concentration in tops varied from to % with the final harvest occurring after different numbers of cuttings for different soils.
· The potassium supplying capacity of the waste mica powder (WMP) was evaluated through chemical and biological means. Four different size fractions of the WMP were studied in laboratory by ...
Potassium is a chemical element with the symbol K (from NeoLatin kalium) and atomic number 19. Potassium is a silverywhite metal that is soft enough to be cut with a knife with little force. Potassium metal reacts rapidly with atmospheric oxygen to form flaky white potassium peroxide in only seconds of exposure. It was first isolated from potash, the ashes of plants, from which .
Physical Properties. ┗ Felspars have a monoclinic or triclinic crystal system. ┗ The refractive index of this mineral is – ┗ The cleavage of feldspar is two. It has two planes intersecting each other at an angle of 90º. ┗ The hardness of this mineral is 6 .
Feldspar is aluminum silie minerals of potassium, sodium, calcium, barium, alkaline earth metal or alkali metal. The main component of feldspar is silicon dioxide, sodium oxide, potassium oxide, calcium oxide, aluminum oxide and so on. It has a low melting point, melting time interval length and other characteristics.
Potassium for crop production. Potassium (K) is an essential nutrient for plant growth. It's classified as a macronutrient because plants take up large quantities of K during their life cycle. Minnesota soils can supply some K for crop production, but when the supply from the soil isn't adequate, a fertilizer program must supply the K.
