“…(Sangeeth et al 2012) enhanced K solubilization by mobilizing inorganic and organic K and liberate of K from rocks and minerals. Rosa-Magri et al (2012) isolated the yeast Torulaspora globosa, from the sugarcane rhizosphere, and evaluated its capacity to solubilization of K from alkaline ultramafic rock powder and found 38 % more total K released in the medium with the yeast during a 15-day period of incubation.…”

“…Further, organic acids formed by KSMs can be detected by high performance liquid chromatography (HPLC) and enzymatic methods (Archana et al 2013;Zhang et al 2013). The acidification is not only mechanism of K solubilization, as the ability to decrease the pH in some cases did not associate with the capacity to solubilize mineral K (Rosa-Magri et al 2012;Zarjani et al 2013). Furthermore, the chelating ability of organic acids is important, because it has been reported that the addition of 0.05 M EDTA in to the medium has similar solubilizing result as inoculation with P. bilaii (Kucey 1988;Liu et al 2006;Sheng and He 2006).…”

Many physical, chemical, and mineralogical factors govern the release of K from micas by cation exchange reaction and dissolution processes. Mainly in Indian agricultural conditions, most of the farmers use only nitrogen and phosphorus and do not use the potassic fertilizer due to unawareness that the problem of K deficiency occurs in soils and it is reported that~72 % of soils need immediate K fertilization for good crop production. The efficient soil microorganisms influence the availability of minerals in soil and play a major role in ion cycling and soil fertility. A number of microorganisms such as bacteria (Bacillus mucilaginosus, B. edaphicus, B. circulans, B. cereus, B. subtilis, B. coagulans, B. amyloliquefaciens, B. megaterium, Enterobacter hormaechei, Flectobacillus spp., Acidithiobacillus ferrooxidans, Paenibacillus spp.), fungal strains (Aspergillus niger, A. fumigatus, and A. terreus), and yeast (Torulaspora globosa) solubilize the insoluble K to soluble forms of K for plant uptake. The main mechanisms of KSMs are acidolysis, chelation, exchange reactions, complexolysis, and production of organic acids. Therefore, the efficient KSMs should be applied for solubilization of unavailable form of K to an available form of K that is taken up by the plant for their growth and development. Therefore, our aim is to elaborate on the studies of native K-solubilizing microbes to develop efficient microbial consortium and their uses as biofertilizers or a biocontrol agent, which helps to enhance the K availability in agricultural soils and increase crop production and environmental and agricultural sustainability.

“…Rosa-Magri et al (2012) reported that a yeast species, Torulaspora globosa, released about 38 % of the total potassium from an alkaline ultramafic rock during a 15 DAI. These workers also demonstrated that the agitation during incubation (which increased oxygen availability) resulted iñ 20 % more bio-solubilization of the alkaline ultramafic rock as compared to the static culture.…”

Bio-weathering and biomineralization are geochemical processes of the decomposition of rocks and minerals which are mediated by the living organisms. These processes play a fundamental role in the release of nutrients from rocks and minerals. Microorganisms, higher plants, and animals can weather rock aggregates through biomechanical and biochemical attack. Among such microbes, the information especially on phosphate solubilizers has been well documented; however, there are very few studies on the use of potassium-solubilizing microbes (KSMs) for the release of the native soil K. The strains of Pseudomonas, Bacillus, Aspergillus, Penicillium, etc. are some known K solubilizers. The principal mechanism for the microbe-mediated release of potassium from minerals is through the production of organic acids. A short overview of the KSMs and their effect of K uptake and crop growth are presented herein. K dynamics in soils and its availability to plants, metabolic pathways effecting the release of organic acids by KSMs, are covered. The aspects of immobilization of KSMs for the ease of application and the role of VAM in K mobilization have also been explored.

“…The production of organic acid can be detected through enzymatic methods and high-performance liquid chromatography (HPLC) (Archana et al 2013). However, acidification is not the only mechanism for K solubilization, because in some circumstances the decrease in pH did not affect the K solubilization (Rosa-Magri et al 2012;Keshavarz et al 2013;Meena et al 2015b). …”

For all organisms potassium (K) acts as an essential cationic nutrient. In plants, K regulates growth and movement of various plant organs and plays a crucial role in biotic and abiotic stress tolerance mechanisms. The rhizospheric microorganisms play an important role in K biogeochemical cycling and may influence K + uptake in crop species by direct and indirect mechanisms. The present article's major emphasis is on the characterization of K-solubilizing bacteria (KSB) and their effect on K uptake, plant development, and growth. Moreover, under various environmental conditions, the importance of K in crop yield improvement and the concentration of K in various plant parts were also described, and the possible molecular mechanism behind this phenomenon will be elaborated.
