Data include time-series measurements, remotely sensed imagery, and high-throughput environmental data from field and laboratory instrumentation. Currently, network-level analyses leverage multi-decadal data from historical, as well as ongoing, and coordinated data collection from several network sites. Though this multifaceted data facilitates analyses on cross-site, regional, and national levels, its analytical power is constrained by the locally organized and siloed management and storage practices in place. A network information management system is crucial for robust meta-analyses and syntheses exploring the agricultural management impacts on agroecosystems production, structure, and function across the various LTAR sites. Foundational tools described herein provide the framework for an LTAR network information system that will empower users to find, harmonize, map, and share data across all network locations. Standard metadata have been created and implemented for (1) inventorying datasets managed by each site, (2) creating controlled vocabularies for measurements to facilitate cross-site comparisons and analyses, (3) geolocating data collection, site, and experimental boundaries, (4) publishing protocols to describe how data were generated, (5) reporting the quantitative research impact of published literature, and (6) using dashboards to visualize the data collection. These efforts serve as a pivot point around which collective work at cross-site, regional, and national levels can occur. Harmonized data and metadata provide a robust foundation for the development of network information management and synergistic data science solutions.</p>","PeriodicalId":15732,"journal":{"name":"Journal of environmental quality","volume":"54 5","pages":"1230-1244"},"PeriodicalIF":2.3,"publicationDate":"2025-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://acsess.onlinelibrary.wiley.com/doi/epdf/10.1002/jeq2.70027","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144022057","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}

This study explores the long-term impacts of increasing P rates on the vertical distribution of soil acidity and Mehlich-3 nutrient availability in long-term trials managed under conservation tillage in North Carolina. In 2022, soil samples were collected from two contrasting long-term trials: one on a sandy, poorly drained Portsmouth soil at Tidewater Research Station (67 years) and another on a well-drained, clay-rich Lloyd soil at Piedmont Research Station (37 years), at depths of 0–5, 5–10, 10–20, and 20–30 cm. In general, the greater crop yield and nutrient removal over the years occurred with higher rates of P, resulting in a decrease in the soil available potassium (K). Historical use of P increased the content of other nutrients that are part of phosphate compounds (i.e., calcium [Ca] and magnesium [Mg]) or are contaminants in these fertilizers (i.e., zinc [Zn] and manganese [Mn]). The distinct trend of sulfur (S) in both locations, where soil available S content increased with P rates at Tidewater and decreased at Piedmont, reflects the complexity of S dynamics in soils with contrasting characteristics. These findings reveal differences between soils and the importance of integrated nutrient management in long-term experiments to avoid bias in the crop response over the years, especially in fields managed under conservation tillage.</p>","PeriodicalId":15732,"journal":{"name":"Journal of environmental quality","volume":"54 5","pages":"1187-1201"},"PeriodicalIF":2.3,"publicationDate":"2025-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://acsess.onlinelibrary.wiley.com/doi/epdf/10.1002/jeq2.70029","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144012797","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}

In response, use of surface water reservoirs for irrigation in the Grand Prairie critical groundwater area (GPCGA) has been implemented toward improving groundwater recovery, but effects of this strategy are unclear. We leverage publicly available satellite imagery and geospatial computational resources to estimate in GPCGA: (1) total surface water area on cropland and non-cropland potentially used for irrigation using a supervised classification model and (2) causal effect of surface water area on groundwater depth-to-water measurements using a two-way fixed effects (FE) model. We show persistent surface water area can be accurately predicted with confusion matrix accuracy ranging from 97.1% to 98.7% compared with known surface water reservoirs. Causal effect of cropland surface water reservoirs on depth-to-groundwater shows an approximate 0.4 m or 3.3% decrease in mean depth-to-water measurements for a given growing season for watersheds with a 100 ha increase in surface water area. Greatest reductions in depth-to-water measurements occur in those watersheds overlying regional cones of depression, corroborating previous groundwater simulation experiments. We note that alternate specifications of FE model exhibited similar effects, indicating FE model robustness.

The study was conducted on field-scale plots in Urbana, IL, during the 2020–2022 growing seasons. Switchgrass was established in 2020 and urea-fertilized at 56 kg N ha⁻¹ year⁻¹. Corn management followed best management practices for the US Midwest, including no-till and 202 kg N ha⁻¹ year⁻¹ fertilization, applied as urea–ammonium nitrate (32%). Our results showed lower direct N₂O emissions in switchgrass compared to corn. Although soil CO₂ emissions did not differ significantly during the establishment year, emissions in subsequent years were over 50% higher in switchgrass than in corn, likely due to increased belowground biomass, which was over five times higher in switchgrass. Nitrate-N leaching decreased as the switchgrass stand matured, reaching 80% lower than in corn by the third year. Differences in ET and WUE between corn and switchgrass were not significant; however, results indicate a trend toward reduced WUE in switchgrass under drought, driven by lower aboveground biomass production. Our study demonstrates that switchgrass can be implemented at a commercial scale without negatively impacting the hydrological cycle, while potentially reducing N losses through nitrate-N leaching and soil N₂O emissions, and enhancing belowground C storage.</p>","PeriodicalId":15732,"journal":{"name":"Journal of environmental quality","volume":"54 3","pages":"576-589"},"PeriodicalIF":2.2,"publicationDate":"2025-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/jeq2.70025","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143930473","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}

The study employs a styrene-based hydrochloride resin (PA202) in an ion exchange process to remove anionic nutrients such as nitrate nitrogen, nitrite nitrogen, and phosphate phosphorus from surface water. Results indicate a dependence between the sorption capacity of the resin and the valency of the targeted nutrient species, which highlights the importance of considering the chemical nature in water treatment strategies. Furthermore, the study integrates the floating barrier and the quartz sand gravel bed with ion exchange to achieve substantial reductions in nutrient concentrations within the reservoir. The quartz sand gravel bed effectively removes organic nitrogen and ammonium nitrogen, contributing to the overall reduction of nutrient levels with minimal financial expenditure. Considering pump expenditure and the achieved nutrient reduction, the operational costs of the Water Quality Improvement Installation, which incorporates both ion exchange resin and quartz sand gravel filter, remain acceptable.
