This study leveraged a 41-year continuous cotton (<i>Gossypium hirsutum L</i>.) system to evaluate how legacy effects of tillage and N fertilization influence BNF, legume N nutritional status, and N sources in hairy vetch (<i>Vicia villosa</i>). Using the ¹⁵N natural abundance method and multivariate analyses, we found that tillage was the dominant factor affecting N dynamics: no-till (NT) plots exhibited higher N status, soil organic matter, soil-derived N, and total N uptake than conventional tillage. Fertilization effects were less pronounced but modulated BNF efficiency. However, NT alone was insufficient to overcome N limitation under unfertilized conditions, as indicated by similarly low nitrogen nutrition index values and overlapping distributions in both CT-0N and NT-0N treatments, highlighting the need for integrated management. These findings underscore how legacy effects of long-term practices shape N acquisition by legumes and support combining NT with crop rotation-specific N fertilization to optimize N inputs and sustain CC performance in low-input systems.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Core Ideas</h3>\u0000 \u0000 <div>\u0000 <ul>\u0000 \u0000 <li>Hairy vetch grown under conventional tillage was more limited by N than no-till, with differences widening at higher N fertilization rates.</li>\u0000 \u0000 <li>Atmospheric N contribution was higher under conventional tillage than no-till, with greater differences at higher fertilization rates.</li>\u0000 \u0000 <li>No-till was associated with higher soil organic matter and soil N uptake, supporting improved legume N status.</li>\u0000 \u0000 <li>No-till alone was insufficient to prevent N limitation in hairy vetch under unfertilized conditions.</li>\u0000 </ul>\u0000 </div>\u0000 </section>\u0000 </div>","PeriodicalId":48502,"journal":{"name":"Agricultural & Environmental Letters","volume":"11 1","pages":""},"PeriodicalIF":3.6,"publicationDate":"2026-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://acsess.onlinelibrary.wiley.com/doi/epdf/10.1002/ael2.70070","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147683423","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite recognition of preferential flows, dating to 1864, and extensive development of nonequilibrium modeling frameworks (e.g., dual-porosity, dual-permeability, and multi-region models), large-scale modeling persistently relies on uniform, equilibrium flow assumptions. The soil science community possesses the theoretical knowledge and mathematical tools to describe nonequilibrium flows, yet practical barriers limit integration into soil health assessments. Bridging this gap requires developing practical parameter estimation protocols, augmenting existing soil-health datasets with nonequilibrium flow characteristics, conducting intercomparison studies, and fostering collaboration between experimentalists and modelers.

This study aimed to determine whether growth-stage-aware ventilation strategies are necessary for effective airflow in small chambers. Using graphics processing unit accelerated, computer-based airflow simulations, we evaluated five fan configurations across four growth stages in a compact platform. Airflow performance was assessed by pixel-based segmentation of velocity fields and point-based diagnostics under plant-present conditions represented by simplified cylindrical models. Results showed that no single fan configuration satisfied airflow requirements across all stages. Case 1 (top-inlet/bottom-outlet) consistently maintained more than 85% active airflow regions across all planes (86.29%–92.90%), effectively minimizing stagnant zones. In contrast, Case 3 (lateral fans) increased mid-canopy airflow activity to over 90% during mid-growth, enhancing canopy penetration. Integrating both analyses, we identified a stage-adaptive sequence (Case 1 → Case 1 → Case 3 → Case 1) that ensured physiologically relevant airflow throughout development.
