Application of native phosphate solubilizing bacteria for the use of cheap organic and inorganic phosphate source in agricultural practise of Capsicum annum (Chili) - A pilot scale field study

Phosphate bacterial solubilization: A key rhizosphere driving force enabling higher P use efficiency and crop productivity

“…and technologies can be co-exploited via concerted research and development efforts to achieve sustainable crop production goal. An example of integrated approach adopted to increase P fertilizers agronomic efficiency was proposed by Jayakumar et al [87] suggesting a combination of both P mineral fertilizers (RP and TSP) and biological resources (PSB, egg shell and animal bone waste). This combination showed an increased (14%) efficiency of TSP when combined with bacterial inoculation.…”

Inoculation With Growth-Promoting Bacteria Associated With the Reduction of Phosphate Fertilization in Sugarcane

“…Inoculation of PGPB with phosphate solubilization capability directly to the soil may increase P availability to the plants by 15 times in the soil (Seneviratne and Jayasinghearachchi, 2005). Soil bacteria increase the solubility of calcium phosphate because majority of these microorganisms have the ability to secrete organic acids (carboxylic acid) which help in the reduction of rhizosphere pH by decoupling the connection between calcium and phosphate (Jayakumar et al, 2019). Solubilizing bacteria may also assist in solubilization of aluminum and iron-bound phosphate and release carboxylic acids which promote direct dissolution of Al and Fe bound P by chelating ions associated with phosphate through a linker exchange mechanism (Tomar, 1998).…”

Enhancing phosphorus bioavailability in lateritic red soil: Combining Bacillus subtilis inoculated microbial organic fertilizer with reduced chemical input

“…Bio‐organic fertilizers inoculated with iron‐reducing bacteria and other beneficial microorganisms can increase agronomic P‐use efficiency and partial factor productivity of P and use Fe as a substrate to promote the release of Fe‐bound P from acidic soils (Naher et al., 2021; Pan et al., 2019). Moreover, a large number of arbuscular mycorrhizal fungi (AMF), P‐solubilizing bacteria and other functional microorganisms can influence the speciation of soil P compounds and improve P availability and efficacy, and they can be used to prepare bio‐organic fertilizers (Etesami et al., 2021; Jayakumar et al., 2017). For example, a consortium of endophyte and rhizosphere phosphate‐solubilizing bacteria improves phosphorous use efficiency in wheat cultivars in phosphorus‐deficient soils (Emami et al., 2020).…”
