Microbial Population Dynamics of Periphyton Biofilms in White Clay Creek

800 532 Stroud Water Research Center

Using glass microscope slides as tiny gardens to grow microbial biofilms, this project explored differences in microorganisms between three reaches of White Clay Creek with different streamside vegetation. Molecular DNA…

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 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 and Updating Data Collection Protocols in National Parks of the National Capital Region

800 532 Stroud Water Research Center

The National Park Service has monitored stream water quality and quantity for more than 15 years in shallow streams located in 10 parks of the National Capital Region Network. This…

Evaluating How Conventional, Conservation, and Organic Farming Management Practices Enhance Soil Health and Improve Water Quality

800 532 Stroud Water Research Center

This project investigates how different agricultural management practices influence water quality and soil health. Using Rodale Institute’s 37-year-old Farming Systems Trial and a recent transition to organic farming at the…

Biological Nitrogen Removal in Sediment Plumes: A Critical but Missing Component of Watershed Models

800 532 Stroud Water Research Center

Nutrient export from rivers is closely tied to sediment plumes that form during storms. By using experiments and methods to peer inside these sediment plumes, this project will discover how…
