To address this research gap, we investigated the impact of three tillage types (conventional tillage [CT], strip tillage [ST], and minimum tillage [MT]) on soil health and water quality on large research plots. Specifically, we measured 10 soil health indicators under the Soil Management Assessment Framework, soil organic C fractionations, and six edge-of-field runoff water quality indicators over 2 years. Edge-of-field water quality was improved in ST and MT plots as compared to CT, with reductions in mean concentrations for particulate constituents (sediment and total Kjeldahl N) approaching approximately 50% or greater. Additionally, indicators of physical soil health (bulk density and water-stable aggregates) and biological soil health (microbial biomass C, soil organic C, potentially mineralizable N, and particulate organic matter C) correlated to decreased concentrations of water quality pollutants. This trend was most pronounced for particulate constituents (e.g., sediment, total Kjeldahl N), which were correlated to indicators of aggregate stability. Furthermore, the lack of difference between ST and MT plots with regards to water quality, soil health, and crop yield indicated that there was little difference between ST and MT.

This study focuses on an unprecedented monitoring program spanning two decades with daily or near-daily sampling across 13 states in the US Midwest and Southern United States, targeting watersheds in the upper 20th percentile of runoff vulnerability based on the United States Geological Survey watershed regressions for pesticides model. The Atrazine Ecological Monitoring Program (AEMP), mandated by the United States Environmental Protection Agency (USEPA), aims to collect extensive high-frequency atrazine exposure data alongside key environmental parameters to better understand the dynamics of atrazine fate, transport, and concentrations in these watersheds. Note, the AEMP is also referred to by the USEPA as the Atrazine Ecological Exposure Monitoring Program, or AEEMP, though the former is more commonly cited. Analysis of the 322 site-years of data revealed that sampling frequency is paramount in accurately estimating seasonal chemical concentrations and runoff loads in flowing waters. The AEMP has advanced with improved sampling techniques and a focus on increasingly vulnerable watersheds (i.e., currently representing 97th–99th centile runoff vulnerability), as evidenced by analysis of variance results indicating higher atrazine concentrations in later years, particularly post-2012. Factors such as soil conditions and precipitation were significant in influencing atrazine levels in surface water. Regression analyses underscored the interaction between agricultural activity and weather patterns as predictors of atrazine concentrations. The AEMP's detailed dataset has notably contributed to environmental risk assessment and the refinement of regulatory models.

Reducing N losses is a complicated problem, as producers have to consider grain protein and yield targets, co-limitations of water and other nutrients, longer term soil health goals, and variability in crop performance across fields. However, past work in the region has established that there are at least four prevalent N performance syndromes, each of which have different environmental effects and lend themselves to different actions for adapting N management. In this paper, we build on this work to develop a discrete six-class evaluation system that simplifies assessment of wheat N performance.

The characterization of fentanyl and its potential degradation products in complex environmental samples such as soil is severely understudied. Very few articles are available that work to identify fentanyl and its degradation products in complex samples or name the possible hazards that may result from environmental exposure and degradation.

Research articles focused on fentanyl between 2000 and 2024 were identified and reviewed and then filtered using Boolean search terms for environmental parameters. Various studies have determined that trace levels of fentanyl can be found in a variety of environments, and additional data suggest preferential partitioning into soils from water and long-term persistence.

Recent studies have shown that in some cases riparian areas are a net source of phosphorus (P) in cold climates. This study assessed the impact of cattle grazing or harvesting of riparian areas on the spatial and vertical distribution of water-extractable phosphorus (WEP). This study measured the WEP in four distinctive sources: biomass, litter, organic layer, and Ah horizon in three riparian locations extending from the edge of the waterbody to the field edge. In addition to a control, three treatments were examined: (1) grazing; (2) high-density grazing; and (3) mowing. Prior to implementing the treatments, the Ah (0–10 cm) soil was the largest pool of WEP (42.5 mg m<sup>−2</sup>, ∼44%); however, the biomass (i.e., standing vegetation) was a considerable proportion of the total (26.3 mg m<sup>−2</sup>, ∼25%) WEP pool. The litter and organic layer had median WEP areal densities of 11.1 and 17.7 mg m<sup>−2</sup>, respectively. Findings revealed significant reductions in biomass WEP with median reductions of 10.4 and 18.7 mg m<sup>−2</sup> for high-density grazing and mowing treatments, respectively. This reduction was more pronounced in the lower riparian locations where there was more biomass available to be grazed or mowed. There were no detectable changes in the other sources of WEP across all the treatments. Assessment of the control plots (pre- and post-treatment) clearly indicates that there is considerable small-scale spatial variability in P measurements in riparian areas. Overall, the results of this study suggest that management practices that target vegetation, including harvesting and short-term autumn grazing, may be mechanisms to reduce the potential P loss during the snowmelt period. To fully assess the risk of P loss, studies investigating other important riparian processes that also have a demonstrated impact on P mobility, including freeze-thaw cycles and flooding, are needed.</p>","PeriodicalId":15732,"journal":{"name":"Journal of environmental quality","volume":"54 3","pages":"634-646"},"PeriodicalIF":2.3,"publicationDate":"2025-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/jeq2.70012","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143677090","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}
