Soil Factors Affecting Potassium Availability Thomas 1968
This chapter serves a purpose by challenging more intensive research on the problems of potassium behavior in soils and plants. The distribution of potassium between negatively-charged sites on the soil and the soil solution is a function of the kinds and amounts of complementary cations, the anion concentration and the properties of the soil cation Release of non-exchangeable K to the third exchangeable form occurs when level of exchangeable and solution K is decreased by crop removal, runoff, erosion and/or leaching (Sparks 1987; Sheng and Huang 2002).The most commonly found soil components of K, 90–98 %, are feldspar and mica (McAfee 2008).In soil, K occurs in Potassium-Solubilizing Microorganisms and Their Role in

Micas Fanning 1989 SSSA Book Series Wiley Online Library
Summary. Dioctahedral micas, such as muscovite, are normally much more resistant to weathering than trioctahedral micas and release K at much slower rates. The layer character of micas controls their properties. Mica synthesis in surface horizons of certain high rainfall soils in Hawaii was proposed by Swindale and Uehara and Juang and Uehara.Potassium is an essential and major nutrient for. known for improving shelf life of crops and. disease resistance (Khawilkar and Ramteke. sium in soil can enhance root growth, improve. droughtPotassium and Its Role in Sustainable Agriculture ResearchGate

Soil Potassium ScienceDirect
This chapter focuses on soil potassium. In the soil-plant system, potassium behaves with extreme differences of solubility and mobility. Thus, its absorption from solutions and soils is highly efficient. Its movement through the plant is very rapid, yet its net retention in individual living cells may be quite strong and some of the bondsSummary. The availability of soil potassium (K) to plants is related to the nature of soil K reserves, the chemistry of the structural configurations and surface properties of soil components involved, and the dynamics and equilibria of K in soil environments. K selectivity of soil particles is affected by mineralogical and chemical Chemistry of Potassium in Soils Huang 2005 ACSESS

Uptake of cesium and strontium cations by potassium
Phlogopite mica was equilibrated with 1.0 N sodium chloride (NaCl)–0.2 N sodium tetraphenylborate (NaTPB)–0.01 M disodium ethylenediaminetetraacetic acid (EDTA) solution at room temperature resulting in an almost complete removal (92%) of the mica's interlayer K. X-ray powder diffraction analysis provides additional evidence that The most important source of potassium in soil is aluminosilicates including feldspars, micas, illite, and vermiculite (Sparks and Huang 1985).Potassium is present as soluble, exchangeable, nonexchangeable, and structural form (Martin and Sparks 1985).The content and type of clay minerals in soil can affect the amount of Effect of canola rhizosphere and silicate dissolving bacteria on the

Potassium Solubilization by Rhizosphere Bacteria: Influence of
Potassium solubilization by rhizobacterial isolates was studied on modified Aleksandrov medium plates by the spot test method[31]. Plates of modified Aleksandrov medium (A) having mica powder (insoluble form of potassium) and medium (B) having soluble form of potassium i.e., K. 2. HPO. 4. were prepared. A loopful of 48-hour old UC RUSAL’s Yaroslavsky Mining Company (Yaroslavsky GRK) is located in the south of the Primorsky Territory, 150 km from Vladivostok. Yaroslavsky GRK was commissioned in 1949 and starting from 1964 it has been producing fluorite concentrate, fluorite briquettes, zinc concentrate, etc. Earlier Yaroslavsky GRK supplied 92% of Comprehensive Processing of Mica Concentrate from Yaroslavsky

Effects of Potassium Removal on the b-Dimension of Phlogopite
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 and of potassium to the point of expanding to produce the kindred mineral, vermi- -culite. Fresh and unweathered micas of predetermined size were treated for varying lengths of time with sodium tetraphenylboron, causing the gradual precipitation of potassium tetraphenylboron and removal of potassium from the micoceous substances.(fl Sk (Review

THE EFFECT of grinding on muscovite has been studied by Mackenzie and Meldau (1956) and Bartha and Bruthans (196 t). In careful wet-grinding experiments (Lodding, 1967), I found that the silica content of the solid muscovite stays essentially constant, but potash is reduced considerably. Grinding for 90 min reduced the KeO content from 10.05 to 8-50 Italian Journal of Agronomy 2017; volume 12:818 Relationship of soil potassium forms with maize potassium contents in soils derived from different parent materials Rashid Mehmood Butt,1 Mohammad Saleem Akhtar,1 Ayaz Mehmood,2 Muhammad Imran,1 Shah Rukh,1 Ghashiya Sattar Kayani,1 Muhammad Tariq Siddique,1 Kashif Sarfraz Abbasi,3 Abdul (PDF) Relationship of soil potassium forms with maize potassium
