Shalamar D. Armstrong's research focuses on how farming practices, especially winter cover crops, affect soil health, water quality, and nutrient loss (like nitrogen and phosphorus runoff) in agricultural watersheds. The work combines field monitoring, soil chemistry, remote sensing, and modeling to evaluate conservation practices at both field and watershed scales. Much of this research is set in Midwest US cropland systems, particularly in Indiana and Illinois.
Publication output has remained fairly steady over the past decade, with some year-to-year variation and a notable increase in output during 2025.
