Moreover, critical knowledge gaps persist regarding how soil particle size fractions interact with organic N pools (labile vs. stable) to influence SNS and spatial distribution across vineyard. This study is the first to validate the Biological N Availability (BNA) method in vineyard soils, demonstrating its field applicability as a rapid, cost-effective tool for quantifying in-season SNS and supporting N management decisions. Here we examined soil N dynamics in 11 vineyards by implementing BNA method to estimate growing season soil N mineralization (GSN) and analyzing N content in distinct soil fractions (>53 µm, <53 µm, and soluble organic N). The stable N pool was close related to the sand-sized fraction, while N in the micro-fraction was more closely associated with the labile N pool and exerted a stronger influence on GSN. Furthermore, the labile N pool was more sensitive to vineyard location and soil depth than the stable N pool, highlighting the importance of site-specific soil management practices. Topsoil in primary grape-growing areas of Nova Scotia could supply approximately 218 kg N·ha<sup>−1</sup> of GSN. By quantifying vineyard SNS using the BNA method and elucidating its interactions with soil fractions and spatial distribution, this study offers novel insights into N dynamics in vineyard soils and provides a foundation for optimizing N use efficiency, enhancing soil health, and reducing environmental risks in perennial cropping systems.</div></div>","PeriodicalId":7512,"journal":{"name":"Agriculture, Ecosystems & Environment","volume":"400 ","pages":"Article 110264"},"PeriodicalIF":6.4,"publicationDate":"2026-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146090178","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, nitrogen fertilization of smooth brome pastures carries nitrate leaching risks, and potential water degradation.

Treatments included mineral nitrogen fertilization, DDGS supplementation, and no fertilization, each under grazed and ungrazed conditions. Biomass (total and live), leaf area index, chlorophyll content, crude protein, acid detergent fiber, neutral detergent fiber, and soil moisture were measured seasonally and across years. Results showed that fertilization consistently produced higher biomass, leaf area index, and crude protein, relative to other treatments, reinforcing its role in sustaining forage productivity. DDGS, while offering a reduced environmental footprint, showed potential in enhancing forage production and quality under average or above average precipitation and soil moisture. However, its efficacy declined during dry years. While long-term fertilization treatment remained the most consistent strategy for sustaining productivity under both ungrazed and rotational grazing systems, DDGS supplementation emerged as a strategic option for regions with adequate growing season precipitation, reducing reliance on mineral fertilizers without compromising yields.

The following variables were determined: soil organic matter, carbon stock, bulk density, total porosity, macroporosity, microporosity, and penetration resistance (0–0.1, 0.1–0.2, and 0.2–0.4 m depth), Visual Evaluation of Soil Structure (VESS) (0–0.25 m depth), and soil macrofauna (0–0.1 m depth). The AFSs showed higher soil organic matter, greater carbon stock, and higher porosity, along with reduced soil bulk density and lower penetration resistance compared with the pasture, with more pronounced improvements in the surface layers. The 25-year AFS exhibited greater macrofauna abundance and higher taxonomic richness, with a notable contribution of ecosystem engineers, indicating advances in soil structural and functional reorganization.

This study investigated the effects of reintroducing traditional management practices on plant diversity in urban habitats, focusing on three factors: management (coppicing and mowing), local environment (soil moisture and sunlight), and landscape context (proportions of urban, agricultural, and forest areas). Specifically, we addressed: (1) whether traditional management practices maintain plant species richness, and (2) how these practices influence local environmental conditions to support biodiversity. Our findings confirm that traditional management fosters plant diversity, aligning with research in Europe.

Maintaining human-nature connections in urban environments is crucial, as traditional practices enhance native plant diversity, aesthetic value, and ecosystem services, such as pollinator support and urban pest control.

However, the absence of MAOC gains under GE14 limited overall SOC accumulation, underscoring the need to optimize grazing exclusion duration.
