We quantified the effects of physical stress on sugarcane root elongation and the role of soil structure in mitigating them, providing experimentally based parameterisations for soil–root interaction via semi-empirical models. Methods Five levels of mechanical and hydric stress were established in soil samples from a long-term experiment under no-tillage (NT 31 ) and conventional tillage (CT 5 ). Repacked soil samples (T 0 ) were created to isolate the pore network effects in mitigating physical stress. Sugarcane seedlings were grown in each structural and physical stress condition, measuring the root elongation rate after 95 h. Semi-empirical models were developed using root elongation rate from each condition as a function of soil penetration resistance and degree of water saturation. Root growth was simulated for 45 days using RootBox model. Results Root elongation rate decreased by 30% in NT 31 and up to 84% in T 0 . The 3D Gaussian model explained 47% (CT 5 ), 71% (NT 31 ), and 78% (T 0 ) of the elongation variability. Under high soil moisture (95%) and penetration resistance (6.2 MPa), root elongation rate in NT 31 was 8.2 times higher than in T 0 and 1.8 times greater than in CT 5 . Simulations showed rooting depth was 2 times greater in NT 31 than in T 0 . Conclusion The semi-empirical models highlighted the key role of soil structure in mitigating physical stress on root elongation, as well as the potential of no-tillage to maintain and recover soil physical functions for root growth.","PeriodicalId":20223,"journal":{"name":"Plant and Soil","volume":"16 1","pages":""},"PeriodicalIF":4.9,"publicationDate":"2026-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149089686","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 assessed the rhizosphere competence of Ensifer meliloti Rm2011 in different barley genotypes following repeated inoculation in three growing seasons, tracking its establishment and influence on the indigenous rhizosphere prokaryotic communities. We aimed to understand how consistent field application affects prokaryotic dynamics and whether environmental conditions or plant genotype modulate its establishment within the rhizosphere community. Methods Three-year field trials evaluated the establishment of E. meliloti Rm2011 in barley rhizosphere and its impact on the prokaryotic community. Rhizosphere samples were collected at several time points throughout the vegetation period and analyzed using colony-forming units and 16S rRNA gene amplicon sequencing to further evaluate the effects of barley genotype and environmental conditions. Results E. meliloti Rm2011 demonstrated robust persistence throughout the growing season, successfully integrating into the rhizosphere community. Despite repeated inoculations, its impact on the native prokaryota was negligible across all years. Neither environmental conditions nor barley genotype had a significant effect on its establishment. Notably, a set of core bacterial taxa was consistently detected, indicating microbiome stability. Further, one ASV assigned to Ensifer was significantly enriched after inoculation in all three years. Conclusion E. meliloti Rm2011 survives and establishes in the barley rhizosphere without modulating the native prokaryotic community composition. Its ecological compatibility and persistence underscore its potential as a microbial inoculant in sustainable crop management. This study highlights the importance of long-term field studies in assessing inoculants' performance and impact on prokaryotic communities.","PeriodicalId":20223,"journal":{"name":"Plant and Soil","volume":"7 1","pages":""},"PeriodicalIF":4.9,"publicationDate":"2026-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149090404","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 assessed the relative importance of soil properties and tested hypothesised direct and indirect relationships regulating P availability across Nigerian agroecosystems. Methods A national dataset of 554 soil samples was analysed. Plant-available P was measured using Mehlich-3 extraction. Random Forest analysis was used to identify dominant predictors and explore non-linear responses, while structural equation modelling was used to test hypothesised direct and indirect relationships among SOC, texture, oxides, acidity, and available P. Results SOC was the strongest predictor of available P. Available P increased with SOC, although the response showed diminishing returns at higher SOC levels. The structural equation model explained 29% of the variation in available P. SOC had the strongest positive direct association with available P. Texture had contrasting effects: finer-textured soils were positively associated with SOC and oxide contents but showed a negative total association with available P. Oxalate-extractable Fe and Al were positively associated with Mehlich-3 extractable P, indicating their role as P-retaining surfaces and potential reservoirs of extractable P. Stronger acidity was negatively associated with available P. Conclusions Available P across Nigerian agroecosystems is shaped by the combined effects of SOC, texture, Fe and Al oxides, and acidity. These findings provide national-scale evidence for targeting established soil fertility practices according to dominant soil constraints across contrasting agroecological zones.","PeriodicalId":20223,"journal":{"name":"Plant and Soil","volume":"9 1","pages":""},"PeriodicalIF":4.9,"publicationDate":"2026-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149067362","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}
