Limited phosphorus (P) bioavailability restricts global agriculture and food production. This element is considered the least plant-available nutrient, it highly susceptible to immobilization in soil matrix. Among mineral fertilizers used increase P fertility, polyphosphates (PolyP) consist of polymers OrthoP residues have been shown improve crop uptake resulting yields more than other forms amendments. PolyP are also known for their progressive hydrolysis, improving availability rhizosphere plant throughout growth stages. However, behavior soils still understudied, including traits likely be involved use efficiency within soil-root-microbe interface. To our knowledge behavioral properties soil–plant continuum, this review among first studies compile, discuss, propose ideas regarding research while focusing on key biochemical factors responsible hydrolysis by roots. A combination exuded P-hydrolyzing enzymes acidification can presumably mobilize available from thereby acquisition. The importance root-associated microbes (exhibiting high P-mobilization capacities) discussed as a promising trait that could contribute greatly boost thus agronomic efficiency.

Abstract By 2050, the predicted global population is set to reach 9.6 billion highlighting urgent need increase crop productivity meet growing demand for food. This becoming increasingly challenging when soils are saline and/or deficient in phosphorus (P). The synergic effect of P deficiency and salinity causes a series secondary stresses including oxidative stress. Reactive Oxygen Species (ROS) production damage plants caused either by limitation or salt stress may restrict overall plant performances leading decline yield. However, application adequate forms doses could positively impact growth enhances their tolerance salinity. In our investigation, we evaluated different fertilizers (Ortho-A, Ortho-B Poly-B) increasing rates (0, 30 45 ppm) on plant's antioxidant system uptake durum wheat (Karim cultivar) grown under (EC = 3.003 dS/m). Our results demonstrated that variations capacity plants, at both, enzymatic non-enzymatic levels. Remarkably, strong correlation was observed between uptake, biomass, various parameters sources. Soluble considerably enhanced total compared with control (C+). Indeed, salt-stressed fertilized exhibited robust revealed activities Catalase (CAT) Ascorbate peroxidase (APX) significant accumulation Proline, polyphenols content (TPC) soluble sugars (SS) as well increased Chlorophyll (CCI), leaf protein unfertilized plants.

Securing a consistent food supply remains pressing global challenge, particularly for small-scale farmers grappling with obstacles in enhancing agricultural yields, especially tropical soils. Integrated Nutrient Management (INM) techniques, employing organic manures like vermicompost and bio-enriched rock phosphate, emerge as recommended solutions. Vermicompost is lauded its nutrient richness positive soil health impacts. At the same time, phosphate serves sustainable alternative to conventional phosphorus fertilisers, specifically tailored conditions. Despite individual studies assessing effects of vermicompost, soluble fertilisers on plant growth, comprehensive overview their combined application noticeably lacking. To fill this gap, study employs Preferred Reporting Items Systematic Review Meta-Analysis (PRISMA) method explore synergies combining these elements impacts crop production environment. This review among first comprehensively summarize complexities chemical various crops.

Published: April 16, 2024

To overcome the problems associated with insufficient available phosphorus in ginseng-growing soil, non-targeted metabolomics and high-throughput sequencing were adopted this study to reveal intracellular metabolites of Pseudomonas P1 their effects on soil bacterial community structure after inoculation. The results showed that although colony number was 4.68×107 cfu/mL 32 h cultivation, stabilized at 24 h. Furthermore, 351 differential (162 189 positive negative ion models, respectively) screened from eight cultivation groups. Venn diagrams revealed more common model (45 metabolites) than (17 metabolites). Organic acids derivatives, 23.53% 15.56% positive- negative-ion respectively, may be dominant involved phosphate dissolution. Although inoculation had little effect diversity, significant changes phyla composition identified between P10 CK. Specifically, relative abundance Pseudomonadales higher CK (P < 0.05). Canonical discriminant analyses correlation analysis shifts closely related physicochemical factors, such as phosphate, total potassium, NH4+-N, NO3--N, pH. Our suggest contain several organic acids, which reduce pH inoculation, affect supply change microbial direction cluster evolution.
