Long-Term Research in Environmental Biology: River Ecosystem Responses to Floodplain Restoration

 800 532 Stroud Water Research Center

After 25 years of litigation, a massive ecological restoration is under way in the Upper Clark Fork River, Mont. Metal-laden floodplain soils are being removed, floodplains are being reconnected with…

Land Protection Impact Assessment in Support of Delaware River Watershed Initiative

 800 532 Stroud Water Research Center

This project evaluates the hypothesis that protection and/or maintenance of natural land maintains ecological stream quality by limiting, preventing, or redirecting changes to land cover and use away from headwaters,…

Impact of Pesticides on Soil and Vegetables Grown in Organic and Conventional Systems in a Long-Term Vegetable System Trial

 800 532 Stroud Water Research Center

This project characterizes microbial soil health through detailed community structure of bacteria and fungi and determines the relationship of microbial structure with application of pesticides under conventional and organic cropping…

Impact of Land Management of Practices on Winter Squash Yield and Post-Harvest Nutrient Density

 800 532 Stroud Water Research Center

By examining the bacteria, Archaea, and fungi living in soils, this project will provide insights on how farming practices and land management affect the microbes that make soils healthy. This…

Exploring the Link Between Soil and Human Health: Protein, Protein Quality, and the Nutraceutical Amino Acid Ergothioneine

 800 532 Stroud Water Research Center

Ergothioneine, an amino acid that has scientifically proven benefits to human health, is exclusively biosynthesized by fungi and certain bacteria in soils. With coupled field testing and lab incubation experiments,…

Evaluating the Risk for PFAS Contamination of Surface and Groundwater Through Application of Biosolids in Agroecosystems

 800 532 Stroud Water Research Center

Per- and polyfluoroalkyl substances (PFASs) are a group of thousands of chemicals that are used in a wide range of industrial applications and represent a risk to human health. They…

Evaluating the Effects of Watershed-Scale Agricultural Best Management Practices on Water Quality

 800 532 Stroud Water Research Center

In early 2020, stream bank fencing, forested buffers, and barnyard improvements were installed on Amish farms in Lancaster County, Pa. The farms are nested in a small watershed drained by…

Evaluating NCRN Data Quality, Revising and Updating Protocols, and Analyzing Long-Term Data

 800 532 Stroud Water Research Center
