The application of chemical fertilizers for plant growth and protection is one the reasons environment ecosystem destruction, thus, sustainable agriculture gaining popularity in research among farming communities. Although most soils are high total phosphorus (P), a large portion unavailable to plants regarded as growth-limiting factor. P-solubilizing bacteria (PSB) exploitation newly developed bio-solution enhancing rhizosphere P availability; however, effect these on soil quality different phases remains unknown. This study aims evaluate impact five strains PSB, isolated from legume rhizosphere, two (Vicia faba Pisum sativum) certain properties. efficient PSB used characterized by P-solubilization, ACC deaminase activity, fixation N, IAA, HCN, siderophores production. activity tested vitro vivo under controlled conditions supplemented with rock (RP). According our findings, all PSBs outperformed control terms legumes percentage ranging 77.78 88.88%, respectively. results showed that treatments significantly improved parameters like nitrogen- (N) P-content (67.50, 23.11%), Also, an increase fresh dry weights above- (41.17, 38.57%) below-ground biomasses (56.6, 42.28%), Compared control, this leads 72% root length, 40.91% weight, 40.07% weight. Rhizospheric displayed levels P, organic matter. All were found have higher alkaline phosphatase, basal respiration, β-glucosidase than control.

Phosphorus is an essential nutrient for all life on earth and has a major impact plant growth crop yield. The forms of phosphorus that can be directly absorbed utilized by plants are mainly HPO42- H2PO4-, which known as usable phosphorus. At present, the total content soils worldwide 400-1000 mg/kg, only 1.00-2.50% plant-available, seriously affects development agriculture, resulting in high level scarcity available Traditional methods applying fertilizer cannot address deficiency problems; they harm environment ore material nonrenewable natural resource. Therefore, it imperative to find alternative environmentally compatible economically viable strategies scarcity. Phosphorus-solubilizing bacteria (PSB) convert insoluble soil into plants, thus improving uptake utilization plants. However, there no clear systematic report mechanism action PSB. this paper summarizes discovery process, species, distribution PSB, focusing physiological mechanisms outlining processes acidolysis, enzymolysis, chelation complexation reactions related genes regulating PSB acidolysis enzymatic well phosphate transport molecular direction its pathway examined. effects structure abundance microbial communities also described, illustrating how interact with microorganisms indirectly increase amount soil. And three perspectives considered further exploring utilizing synergistic multi-omics approach, PSB-related regulatory different levels investigating application fungicide. This aims provide theoretical support providing optimal management elemental future.

Salt stress impacts phosphorus (P) bioavailability, mobility, and its uptake by plants. Since P is involved in many key processes plants, salinity deficiency could significantly cause serious damage to photosynthesis, the most essential physiological process for growth development of all green Different approaches have been proposed adopted minimize harmful effects their combined effect. Optimising nutrition seems bring positive results improve photosynthetic efficiency nutrient uptake. The present work posed question if soluble fertilizers allow wheat plants counter adverse effect salt stress. A pot experiment was performed using a Moroccan cultivar durum wheat: Karim. This study focused on different responses grown under P-availability. Two Orthophosphates (Ortho-A & Ortho-B) one polyphosphate (Poly-B) were applied at levels (0, 30 45 ppm). Plant analysed some parameters (stomatal conductance (SC), chlorophyll content index (CCI), fluorescence, shoot root biomass, mineral uptake).

Abstract Ensuring plant resilience to drought and phosphorus (P) stresses is crucial support global food security. The phytobiome, shaped by selective pressures, harbors stress-adapted microorganisms that confer host benefits like enhanced growth stress tolerance. Intercropping systems also offer through facilitative interactions, improving in water- P-deficient soils. Application of microbial consortia can boost the intercropping, although questions remain about establishment, persistence, legacy effects within resident soil microbiomes. Understanding microbe- plant-microbe dynamics drought-prone soils key. This review highlights beneficial rhizobacterial consortia-based inoculants legume-cereal intercropping systems, discusses challenges, proposes a roadmap for development P-solubilizing drought-adapted consortia, identifies research gaps crop-microbe interactions.

Abstract Phosphorus (P) is a macronutrient that plants need to grow. However, most of the soil’s phosphorus still insoluble, making it difficult for absorb. This creates barrier ecologically responsible farming methods and calls innovative approaches solubilization. Solublizing microorganisms improve availability phosphorous in soil. The term “phosphorus-solubilizing microorganisms” (PSMs) describes various fungi or bacteria divide into more soluble forms. It shows how PSMs interact with their processes solubilize phosphorus. Soil pH, temperature, nutrient are only few parameters affecting its activity. investigated potential increase plant absorption use, thereby boosting agricultural yield usage efficiency. use effects on environment also evaluated. By using PSMs, farmers may less chemical fertilizers contribute runoff eutrophication waterways. Furthermore, soil structure, decrease losses, cycling, all which health long-term viability systems.
