“…B. Sharma et al, 2013). Nevertheless, the main mechanism of inorganic P solubilization is largely proposed to be by organic acids (Billah et al, 2019;Pande et al, 2017;Rafi et al, 2019;Walia et al, 2017), whose carboxyl and hydroxyl ions act by lowering soil pH, chelating cations like iron, aluminum, and calcium ions bound to P, competing with P for adsorption sites in soil and/or forming soluble complexes with metal ions associated with P (P. N. Bhattacharyya et al, 2016;Billah et al, 2019; S. T. Patel & Minocheherhomji, 2018;Pradhan et al, 2017;S. B. Sharma et al, 2013).…”

“…Kumar et al, 2018), but more light needs to be shed on this. Apart from organic acids, other chelating substances, and inorganic acids such as sulphiridic, sulfuric, nitric, and carbonic acids (Pande et al, 2017;Walpola & Yoon, 2013) are also considered as alternative P solubilizing mechanisms of PSB, but their contribution and effectiveness in this regard are limited (Alori et al, 2017;Pradhan et al, 2017).…”

“…Bhattacharyya et al, 2020). Phytases, on the other hand, mediate the degradation of phytate or phytic acid which is the major component of organic P in soil (Dash et al, 2017;Pradhan et al, 2017). Plants generally cannot acquire phosphorus directly from phytate, however, the presence of PSM in the rhizosphere may compensate for this (Richardson & Simpson, 2011).…”

“…According to Pradhan et al, (2017) these microorganisms can also protect plants against phytopathogens and have a high cost-benefit ratio because of low-cost production technologies. This is because their formulation largely involves the use of agribusiness waste products which are readily and cheaply available.…”

“…Phosphorus (P) is the second-most important nutrient after nitrogen in terms of plant growth and development (Alori et al, 2017;Kalayu, 2019;Mitra et al, 2020;Pradhan et al, 2017). This nutrient element is important in virtually every metabolic process in plants from photosynthesis, biosynthesis of macromolecules, and respiration to energy transfer and signal transduction (Billah et al, 2019;M.…”

Phosphorus (P) is the second-most important element after nitrogen that is required for plant growth. Although this element is abundant in most soils, it is rarely available in plant-accessible forms since most of it normally exists in soil in insoluble forms such as phosphates. In conventional agriculture, P is normally supplied as chemical fertilizer to satisfy plant P requirements. This, to a large extent, boosts plant production. However, chemical fertilizers are costly, have a huge carbon footprint, and are environmentally-unsustainable owing to the high energy requirements during their synthesis. Besides, P-containing agricultural run-offs contribute hugely to the eutrophication of water bodies and environmental degradation. Moreover, plants can consume only a small amount of chemically-supplied P since between 75 and 90% of this form of P normally get precipitated into complexes and rapidly become fixed in soil. These issues and concerns necessitate research into alternative and viable ways of supplying P to plants. Rhizobacteria have for decades been investigated in vivo and in planta as suitable tools in sustainable agriculture due to the plant-growth-promoting activities such as nutrients’ solubilization, nitrogen fixation, and production of phytohormones. Although a lot of research has been done on different nutrients-solubilizing rhizobacteria and their potential in sustainable agriculture, their mechanisms of action and prospects in sustainable agriculture remain to be fully understood. This review particularly focuses on the P solubilizing rhizobacteria and evaluates their diversity, mechanisms of action, and prospects in sustainable agriculture based on the present and future scenario of their application. Such information is useful in determining their potential and evaluating their prospects in promoting sustainable agricultural systems.

Soil microbes greatly contribute to the regulating of phosphorus (P) cycling, which plays a significant role in maintaining wetland ecosystem processes and function. The microbial functional diversity of soil P cycling in response to wetland degradation, however, remains largely unknown. We used metagenomic sequencing to investigate the microbial community and genes related to soil P cycling in un-degraded marshes and meadows derived from long-term marsh degradation in the Lalu alpine wetland of the Tibetan Plateau. When the marsh degraded into meadow, organic P (OP) mineralization genes increased while genes related to P-starvation response regulation decreased. Proteobacteria (20.5-74.3%) and Actinobacteria (5.6-59.7%) were the dominant phyla in soils and were also the main contributors (39.7-84.1% in total) to soil P-cycling genes. Soil pH was the primary factor influencing the P-cycling functional genes. Soil pH negatively affected the genes related to the P-uptake and transport system and had negative effects on the genes related to P-starvation response regulation, OP mineralization, and inorganic P solubilization. These findings may deepen our understanding of the biogeochemical process of soil OP and may be beneficial for wetland management.
