POTASSIUM AVAILABILITY AND SOIL EXTRACTION TESTS IN AGRICULTURAL SOILS WITH LOW EXCHANGEABLE POTASSIUM CONTENT

Potassium availability and soil extraction tests in agricultural soils with low exchangeable potassium content

Low application of fertilizer potassium (K) in intensive agriculture leads to a gradual decrease and, afterwards, to a steady state of soil K determined by tests which are based on soil exchangeable K (Kexch) extraction.In this situation, non-exchangeable K (Knon-exch) is being released and therefore real plant availability does not necessarily cor

Ion exchange-assisted surface passivation toward highly stable red-emitting fluoride phosphors for light-emitting diodes

Abstract A facile and environmentally friendly ion exchange-assisted surface passivation (IASP) strategy is presented for synthesizing red emitting Mn4+-activated fluoride phosphors.A substantial, pristine Mn4+-free shell layer, applied as a coating to Mn4+ doped Dust Mop Handles potassium fluorosilicate K2SiF6:Mn4+ (KSFM) phosphors, enhances both
