{"title":"Silicon-mediated alleviation of salinity stress in wheat is linked to reduced sodium accumulation but depends on cultivar and silicon source","authors":"Jannatul Ferdous,Rhiannon Rowe,Kun Ning,Zhong-Hua Chen,David T. Tissue,Scott N. Johnson","doi":"10.1007/s11104-026-09104-3","DOIUrl":"https://doi.org/10.1007/s11104-026-09104-3","url":null,"abstract":"Abstract Background and aims Soil salinity constrains crop productivity globally, yet mitigation strategies often involve economic or environmental trade-offs. Silicon (Si) supplementation is a potential approach to alleviate salinity stress, although responses are inconsistent and may depend on Si source and plant genotype. This study aimed to quantify growth responses of contrasting wheat cultivars to salinity and evaluate whether different Si sources modify these responses by reducing sodium (Na  + ) accumulation. Methods Ten wheat cultivars were grown under saline or non-saline conditions and treated with one of three Si supplementation regimes: granular amorphous Si, liquid amorphous Si, and liquid potassium silicate. Plant biomass and foliar Si and Na + concentrations were measured and compared with non-supplemented plants. Results Salinity reduced root and shoot biomass by approximately 36% and 26%, respectively, across cultivars, with substantial cultivar variation in sensitivity. Si-mediated mitigation of salinity-induced biomass loss was strongly dependent on cultivar and Si source, ranging from substantial growth improvements (+ 114% and + 133% in roots and shoots, respectively) to neutral or negative responses. Liquid Si formulations provided the most consistent alleviation of salinity-induced biomass loss. Where effective, Si supplementation reduced shoot Na + accumulation under saline conditions and there was a negative correlation between foliar Si and Na + in five of the ten cultivars. Conclusion Si supplementation mitigates salinity stress in wheat, potentially by reducing Na + accumulation, but its effectiveness depends on both cultivar and Si source. Liquid Si offers more consistent short-term benefits. Cultivar selection with targeted Si management may therefore underpin crop resilience to salinity.","PeriodicalId":20223,"journal":{"name":"Plant and Soil","volume":"8 1","pages":""},"PeriodicalIF":4.9,"publicationDate":"2026-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149092133","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}

{"title":"Using recovered road sweepings in manufactured soils: a Betula pendula growth trial","authors":"Daniel Niepsch,Edward Randviir,Rebecca Murphy-Peers,David Megson,David Hackett,Peter Stringer,Emma Coulthard","doi":"10.1007/s11104-026-09175-2","DOIUrl":"https://doi.org/10.1007/s11104-026-09175-2","url":null,"abstract":"Abstract Background and aim Sustainable soil management practices are required to reverse degradation and maintain or create ‘healthy soils’. Reclaimed and treated street cleansing residues (SCRs), which are produced in large quantities and often added to landfill, can potentially provide a suitable ‘circular economy’ alternative to virgin soils. Methods The response of silver birch ( Betula pendula; N  =  60 ) – a fast-growing and common street tree – was tested in a range of manufactured soils derived from SCRs ( N  = 4) and compared against a range of commercially-available comparator soils ( N  = 4) to assess the suitability of the manufactured soils and identify any potentially deleterious elements within the waste-derived soils to either be removed within the process or mitigated in subsequent soil refinements. Key soil parameters (including pH, organic matter and carbon and nitrogen contents) together with tree-health parameters (using non-destructive techniques, e.g. tree growth, chlorophyll estimation/extraction and leaf nitrogen contents) were monitored over a 12-months period. Results Different physico-chemical properties were recorded for the tested soils, with higher pH, elevated C:N ratios and organic matter contents in the waste-derived (-blend) soils, which performed comparably to commercial soils in supporting tree growth, but also showed significant differences in tree growth. Smartphone-based techniques, e.g. contact-image chlorophyll estimation approaches showed suitability to monitor ‘overall tree health’, whereas extracted chlorophyll and leaf nitrogen contents showed healthy tree growth in B. pendula . Conclusion This research demonstrates for the first time that recovered road sweepings can grow healthy trees and can therefore be used successfully as a soil in urban planting schemes. If scalable and pending regulatory approval and more extensive testing (i.e. additional species, longer growing periods), use of road sweeping derived soil could be a significant benefit to the circular economy of urban regions, providing a valuable use for otherwise discarded waste, supporting urban greening agendas, and reducing the demand for natural soils.","PeriodicalId":20223,"journal":{"name":"Plant and Soil","volume":"84 1","pages":""},"PeriodicalIF":4.9,"publicationDate":"2026-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149090313","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}

We therefore tested how young grassland communities respond to CDHW regarding physiological performance, biomass stability and species persistence. Methods In a controlled growth-chamber experiment, we established mesocosms of three functionally contrasting forage species ( Lolium perenne L., Cichorium intybus L., Trifolium repens L.) grown in monocultures and mixtures. Communities were exposed to ambient or CDHW conditions. Gross primary production (GPP), soil moisture, evapotranspiration and leaf water potential tracked stress and recovery dynamics, while biomass and species proportions were assessed at harvest. Results CDHW reduced GPP in most communities, with species-specific physiological strategies: T. repens showed the highest resistance, whereas C. intybus , despite a 24% decline in GPP, showed the strongest recovery. Mixture responses were intermediate, with 37%–47% GPP reductions, reflecting grass dominance rather than complementarity. At harvest, mixtures equalled but did not exceed the best monoculture, but generally showed greater biomass stability and enhanced net diversity effects under CDHW. Dominance of L. perenne increased under CDHW, from on average 72% biomass under control to 96%. Conclusion Grassland mixtures buffered biomass losses during CDHW events but lacked physiological facilitation. Biomass stability did not prevent reinforced grass dominance, highlighting a specific risk: should CDHWs strike during establishment, they can undermine successful grassland mixture formation, limiting long-term ecosystem service delivery under climate change.","PeriodicalId":20223,"journal":{"name":"Plant and Soil","volume":"37 1","pages":""},"PeriodicalIF":4.9,"publicationDate":"2026-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149092135","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}

This study developed and tested a simple, high-throughput screening protocol under controlled environmental conditions to identify critical thresholds to seedling emergence in field soils. Methods Soil water retention curves and early canola development responses to soil water potential were assessed prior to developing a tube-based system in which soil conditions could be manipulated. The system was tested by assessing the response of canola seedling emergence to soil strength (0–5.5 kg/cm 2 ) above the seed and sowing depth (2, 5, 10 cm) across different soils using the variety ‘Regiment XT’. Reduced strength x depth treatments derived from this were then used to screen the emergence of novel genotypes (long- and short hypocotyl). Results The non-limiting water threshold for maximum germination and cotyledon emergence across soil types was -250 kPa. Critical soil strength values, 4.8 kg/cm 2 in sand, and 2.5 kg/cm 2 in a loam were established at a 2 cm sowing depth but declined in both soils to < 1 kg/cm 2 as depth increased below 5 cm. The methodology confirmed previously established differences in emergence between long- and short hypocotyl canola varieties. Conclusions A controlled-environment, tube-based system in which several soil, environmental, management and genetic variables were manipulated to establish critical thresholds for canola emergence was effective for studying factors influencing seedling emergence, and providing a field-relevant rapid screening methodology.","PeriodicalId":20223,"journal":{"name":"Plant and Soil","volume":"18 1","pages":""},"PeriodicalIF":4.9,"publicationDate":"2026-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149090320","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}
