“…Phosphorous uptake by plants depends on the existence of bioavailable phosphate in root vicinity (Bargaz et al 2021). Despite excessive presence of phosphate in agricultural soils, it is one of the most common crops limiting factor as its significant fraction is locked into various in soluble organic and inorganic forms (Adebayo et al 2023). Plant available forms are quite low in soils i.e., 0.1 to 10 μM which is quit below the plant optimum phosphate demand.…”

Rhizosphere engineering approach is considered a quantum leap in plant sciences. The current study focused on investigating rhizobacterial efficiency to mobilize bioavailable phosphate from insoluble-phosphate source. Phosphate-solubilization potential of four efficient phosphate solubilizing bacterial strains i.e., Pseudomonas songnenensis (GR3), Stutzerimonas stutzeri (HH2), Bacillus bingmayongensis (KH3) and Achromobacter aegrifaciens (MH1) was analyzed. The bacterial strain GR3 was observed as most efficient phosphate solubilizer. Interactions between various physiological parameters and phosphate solubilization efficiency of isolates was evaluated using surface response methodology. In-vitro experiments revealed that glucose significantly facilitated phosphorus solubilization at 37 ℃, with media having pH 7 and 0.5% phosphorous. Additionally, positive correlation among P-solubilization potential, acids produced and pH variations was observed. Plant microbe-interaction analysis was performed to evaluate the efficiency of these bacterial strains on various morpho-physiological responses of Zea mays L. For this purpose, various concentrations of tricalcium phosphate were applied to plants in the presence and absence of bacterial strains. The results showed that, lower phosphate levels trigger shoot development, improve plant weight and leaf formation whereas higher phosphate concentrations stimulated the development of longer root system. The bacterial strains GR3 and HH2 were observed as efficient phosphate-solubilizing bacteria (PSB) that positively stimulated plant morphological responses by triggering various biochemical attributes such as plant protein content, phytohormone homeostasis, macromolecule content, solute content and pigment content. Hence, the current study reviled that the use of these phosphate solubilizing PGPR are efficient phytostimulators used for crop production in replacement of chemical fertilizers which are carcinogenic and deteriorating our eco-system.

Phosphorus (P) is a macronutrient that plants need to grow. However, most of the soil’s phosphorus is still insoluble, making it difficult for plants to absorb. This creates a barrier to ecologically responsible farming methods and calls for innovative approaches to phosphorus solubilization. Solublizing microorganisms improve the availability of phosphorous in soil. The term “phosphorus-solubilizing microorganisms” (PSMs) describes various fungi or bacteria that divide the phosphorus into more soluble forms. It shows how PSMs interact with plants and their processes to solubilize phosphorus. Soil pH, temperature, and nutrient availability are only a few parameters affecting its activity. PSMs are investigated for their potential to increase plant phosphorus absorption and use, thereby boosting agricultural yield and nutrient usage efficiency. The use of PSMs and their effects on the environment are also evaluated. By using PSMs, farmers may use less chemical phosphorus fertilizers that contribute to runoff and eutrophication in waterways. Furthermore, PSMs may improve soil structure, decrease nutrient losses, and increase nutrient cycling, all of which contribute to soil health and the long-term viability of agricultural systems. Phosphorus-solubilizing microorganisms have enormous promise in environmentally responsible farming and land management. Better phosphorus availability, greater agricultural output, less pollution, and better soil health are all possible outcomes of using PSMs. However, further study is required to determine the best application strategies, formulations, and choices of PSMs for various soil and plant systems. Incorporating PSMs into agricultural operations can potentially improve environmental sustainability and resilience. This article will explore the potential of PSMs in addressing critical environmental challenges, including soil erosion, nutrient runoff, sustainable farming practices, and resource conservation.
