“…The overall results of this experiment is the treatment of P and K rocks with P-and K-solubilizing bacterial strain were sustainable and alternative of chemical fertilizer for crop production. Bagyalakshmi et al (2012) reported that the K-solubilizing stains were isolated from rhizosphere of tea and used as biofertilizers of K in tea that have a solubilizing capacity of muriate of potash (MOP) was increased as compared to mineral K sources. Supplementation of glucose and ammonium nitrate was found to be highly effective in solubilization of MOP as compared to the other sources which should be considered prior to the application of these strains in tea soils as bio-inoculants.…”

Increasing cost of the fertilizers with lesser nutrient use efficiency necessitates alternate means to fertilizers. Soil is a storehouse of nutrients and energy for living organisms under the soil-plant-microorganism system. These rhizospheric microorganisms are crucial components of sustainable agricultural ecosystems. They are involved in sustaining soil as well as crop productivity under organic matter decomposition, nutrient transformations, and biological nutrient cycling. The rhizospheric microorganisms regulate the nutrient flow in the soil through assimilating nutrients, producing biomass, and converting organically bound forms of nutrients. Soil microorganisms play a significant role in a number of chemical transformations of soils and thus, influence the availability of macro-and micronutrients. Use of plant growth-promoting microorganisms (PGPMs) helps in increasing yields in addition to conventional plant protection. The most important PGPMs are Azospirillum,

“…Potassium (K) is the third macro-nutrient required by the crop plants (Bagyalakshmi et al, 2012) and plays a significant role in growth, yield and activation of several metabolic processes including protein synthesis, photosynthesis, enzymes, besides providing resistance to diseases and insects etc (Rehm and Schmitt, 2002). The sustainable nutrient management practices have mainly been focussed on supply of N and P while the issue of sustainable management of K in soil has partly been ignored.…”

“…Isolate XF11 exhibited the most pronounced positive effect on plant augmentation and nutrient uptake by tobacco seedlings. In an interesting research work by Bagyalakshmi et al (2012), it showed that inoculation of tea plants with K-solubilizing bacteria (Pseudomonas putida) leads to the improvement in the productivity and nutrient uptake in plants. Tea quality parameters such as theaflavin, thearubigin, highly polymerized substances, total liquor color, caffeine, briskness, leaf color, and flavor indexes were greatly improved in K-solubilizing bacteria-treated plants.…”

The plant rhizosphere harbor array of potassium-solubilizing microbes (KSMs), which solubilize the insoluble and inaccessible potassium (K) to accessible forms of potassium for plant uptake and transport, is one of the inevitable elements for growth and yield. The process of potassium solubilization is performed by specific rhizosphere microbes, which include bacteria and fungi; the prominent are Bacillus sp. (B. megaterium, B. mucilaginosus, B. edaphicus, B. circulans, Acidithiobacillus ferrooxidans, Pseudomonas putida, Arthrobacter sp., and Paenibacillus sp.) Aspergillus spp., and Aspergillus terreus. The agricultural soil particulates contain minerals such as orthoclase, illite, biotite, feldspar, and mica which contain potassium, though this is not available to the plants due to its immobilized form. Intermittently, potassium is an important element after N and P in soil chemistry; therefore, the rhizosphere microbes play a significant role in mobilizing the unavailable form of potassium to the plant roots. The potential rhizosphere K-solubilizing microbes such as Pseudomonas, Bacillus, and Aspergillus excrete organic acids, which solubilize the unavailable potassium and make available to plant roots. Till date, most of the work has been done on nitrogen-fixing and phosphate-solubilizing microbes; moreover, the available biofertilizer with solubilized K (readily available) needs more attention at commercial scale. The current chapter addresses the information gaps related to potassium-solubilizing/potassium-mobilizing microorganisms in soil and analyzing current and future aspects of potassium-solubilizing microbes for the crop productivity.
