In large part, this is because assessing the social well-being outcomes of sustainable agricultural practices lacks a widely accepted framework. This study fills the gap by identifying community well-being domains and attributes related to the impacts of agricultural management. Semi-structured interviews via Zoom with 42 underrepresented producers across the United States during the winter of 2021 captured producers' perceived broader community well-being outcomes of soil health management. Producers were selected to represent Long-Term Agroecosystem Research (LTAR) network sites and interests, a national network of diverse cropping, livestock, and integrated agricultural research sites. Two rounds of coding, first inductive and then deductive, were based on the community well-being framework and the 4Cs of ecosystem assessment: conditions, capabilities, connections, and crosscutting. The data revealed three major domains of how soil health management contributes to the conditions, capabilities, and connections that underlie community well-being, aligning with the 4Cs framework. Within these three domains, we identify 16 attributes specific to agricultural management, including sense of place, recreation and tourism, and community safety, among others. These domains and associated attributes notably expand the range of measurable outcomes of soil health practice adoption. The new data contribute to the development of social sustainability indicators and efforts to foster diversity, equity, and inclusion within agricultural innovation. Additionally, this research provides an empirical, theoretically based framework of social sustainability indicators for agricultural sustainability assessments across the LTAR network.</p>","PeriodicalId":15732,"journal":{"name":"Journal of environmental quality","volume":"54 5","pages":"1214-1229"},"PeriodicalIF":2.3,"publicationDate":"2025-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://acsess.onlinelibrary.wiley.com/doi/epdf/10.1002/jeq2.70049","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144325929","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We studied the interactions between PFOS and DOM from locally sourced and commercial organic amendments, including biosolids, animal manure, composts, and humic acid. Additionally, we measured PFOS adsorption on a kaolinitic Ultisol (Gwinnett) and adsorption–desorption on a smectitic Vertisol (Vaiden). PFOS affinity for DOM was strongly correlated with the humification index (HIX, <i>r</i>² = 0.94), protein-like fluorophores (C3, <i>r</i>² = 0.76), and aromaticity (specific UV absorption at 254 nm [SUVA₂₅₄], <i>r</i>² = 0.71). The presence of 100 mg C L⁻¹ DOM from biosolids and animal waste enhanced PFOS adsorption by up to 90%, whereas DOM from plant and terrestrial sources reduced adsorption by as much as 40%.

This paper also explores the temporal and seasonal patterns of PFAS emissions, as well as the fate of both long- and short-chain PFAS compounds. Furthermore, it discusses the partitioning behavior, bioaccumulation, and trophic magnification of PFAS in estuarine environments. PFAS are widespread in estuary sediment and surface water, and sediments continue to serve as a significant reservoir for these substances. The temporal trend suggests that the introduction of legislation and the gradual phaseout of some PFAS groups may have led to a decrease in their concentration levels.

This 3-year study on a clay loam soil compared NH₃ losses, N₂O emissions, and corn (<i>Zea mays</i> L.) grain yields for pre-plant urea ammonium nitrate (UAN) injection versus side-dress UAN injection using no inhibitors, a urease inhibitor, or a urease and nitrification inhibitor.

Pre-plant UAN with a urease inhibitor had 59% greater N₂O emissions (2.15 kg N ha⁻¹) than pre-plant injected UAN with a urease and nitrification inhibitor (1.35 kg N ha⁻¹); pre-plant UAN injection with no inhibitors produced intermediate N₂O losses (1.89 kg N ha⁻¹).

The dual urease and nitrification inhibitor treatment reduced yield-scaled N₂O emissions by 37% compared to urease only when averaged over the timing treatments. Side-dress N application reduced yield-scaled N₂O emissions by 28% compared to pre-plant application when averaged over the inhibitor treatments.

We used monitoring data to test the WPI's ability to identify P loss tradeoffs between tilled corn silage and perennial forage cropping systems and WPI's sensitivity to treatment differences within each cropping system. Overall, WPI P loss estimates were supported by monitoring results, with higher total P losses for the corn system dominated by PP (84%) and smaller losses from the perennial forage system dominated by DP (86%). Notably, the WPI also distinguished most treatment differences within systems. Greater than 50% of annual runoff occurred during winter for both systems and was generally underestimated by WPI.

Early conservation agriculture systems in the United States and other continents have informed CASI since its inception in 1998, with an emphasis on reducing soil disturbance for better soil structure and biological activity, retaining biomass on the soil to support soil life, and diversifying crops to enhance biodiversity.

With timelines of its core research and extension education programs, practice adoption trends, and resource quality impacts, CASI's specific accomplishments are described and compared with the dominant tillage-intensive conventional systems of the past 90 years for crops such as corn, small grains, tomatoes, cotton, dry beans, and melons. An associated 25-year research station trial has shown that no-tillage and cover crop practices maintain productivity, increase soil quality (e.g., soil carbon and nitrogen, aggregation, and infiltration), greatly reduce dust that is detrimental to human health, and decrease annual production costs by $50–$75 per acre.
