Silicon (Si) also exhibits affinity for these compounds and can displace P into the soil solution. Studies evaluating application timing to increase P availability remain scarce. This study evaluated the effect of Si and P application timing on soil P availability and maize growth. Methods The experiment was conducted in a greenhouse using a randomized block design with four replicates. Six treatments were evaluated: Control (without P and Si); P applied at sowing (100 mg kg⁻ 1 ); Si applied at sowing (480 mg kg⁻ 1 ); P applied 30 days before sowing + Si at sowing; Si applied 30 days before sowing + P at sowing; and P + Si applied together at sowing. At 60 days of maize cultivation; physiological parameters, biomass, P and Si concentration and uptake, and soil P fractionation were evaluated. Results The results demonstrated that Si applied 30 days before sowing + P at sowing, or P + Si applied together at sowing, increased available P in soil. The P + Si combination, regardless of the application timing, did not increase P concentration and uptake in maize plants. Conclusion The application of Si before P, or the joint application of P and Si, can be an alternative to increase available P levels in tropical soil, however, no influence of the timing of P and Si application was observed on maize growth.","PeriodicalId":20223,"journal":{"name":"Plant and Soil","volume":"18 1","pages":""},"PeriodicalIF":4.9,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149090400","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Phosphate solubilizing bacteria (PSB) can break down these insoluble metal cation complexes and increase plant available forms of phosphorus. This study aims to identify and characterize iron PSB that enhance phosphorus availability in soilless greenhouse systems. Methods A collection of 1044 rhizobacterial isolates was screened for iron phosphate solubilization using a malachite green colorimetric assay. Isolates demonstrating greater than 25 percent solubilization of supplied FePO 4 ·2H 2 O were selected, sequenced, and classified taxonomically. These candidate strains were assessed in greenhouse trials under phosphorus limited conditions to evaluate plant growth promotion. Whole genome sequencing and functional annotation were performed to identify genes involved in phosphate solubilization and rhizosphere adaptation. Results Malachite green assay screening identified 24 high performing strains with strong FePO 4 ·2H 2 O solubilization ability. Greenhouse evaluation showed that Pantoea communis C3A8 , Pantoea formicae C8D10, Pseudomonas sp. C6E7, Pseudomonas sp. C9D1 and Priestia megaterium C3F10 improved spectral indicators of plant quality in French marigolds, while three of the strains (C3A8, C8D10, and C6E7) also increased shoot digital biomass. Strain C3A8 significantly increased shoot tissue P content. These strains encode unique genes supporting multiple phosphorus solubilization mechanisms as well as traits for effective rhizosphere colonization. Conclusion These findings highlight the importance of targeted screening and genomic analysis for identifying effective iron PSB strains, supporting the development of strategies aimed at reducing fertilizer inputs and promoting sustainable nutrient management in greenhouse crop production.","PeriodicalId":20223,"journal":{"name":"Plant and Soil","volume":"36 1","pages":""},"PeriodicalIF":4.9,"publicationDate":"2026-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149090403","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Current detection methods rely on DNA-based assays, which cannot distinguish between viable and dead S. scabies . RNA-based assays may provide a more reliable indication of pathogen activity in soil. This experiment evaluated whether RNA-based detection improves prediction of disease severity. Methods In a growth chamber experiment, soils were artificially infested with S. scabies and seeded with radish. Soil collected prior to radish transplant and following harvest was extracted for both DNA and RNA. Both qPCR and rt-qPCR were used to quantify: i ) the constitutively expressed 16S rRNA, and ii ) the facultatively expressed txtAB , which facilitates tuber infection. Disease severity was evaluated against pre-season and post-harvest gene abundances. Results A clear gradient in S. scabies density was detected using genomic txtAB and genomic and transcribed 16S rRNA abundances. Transcribed txtAB was not detected. Despite a clear gradient in S. scabies , no assay reliably predicted disease severity. Conclusions Our results suggest two fundamental constraints at the intersection of plant pathology and soil science: i ) the success of RNA-based assays for detecting pathogen activity is constrained by gene copy number and sampling time, especially when virulence factors are facultatively expressed, and ii ) detection of pathogens, even in a metabolically active state, does not necessarily provide sufficient information to predict virulence expression, decoupling active pathogen presence from disease severity.","PeriodicalId":20223,"journal":{"name":"Plant and Soil","volume":"5 1","pages":""},"PeriodicalIF":4.9,"publicationDate":"2026-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149090402","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
