For years Dr. Gurpal Toor and his students have gathered and analyzed water samples to examine agricultural runoff from a six-acre field in Prince George’s County and 14 other agricultural sites. Dr. Toor and his lab are working towards more precise answers to how much nutrient runoff finds its way into local waterways that ultimately flow to the Chesapeake Bay.

Seasonal variations and changes in rainfall, temperature, crops planted and agricultural techniques all feed into to complexity of tracking and modeling runoff. With around 80,000 farms in the Chesapeake watershed, understanding nutrient flow is vital to our regional environment, economy, and Bay health.

The Bay Journal recently published an in-depth expose on Dr. Toor and his lab’s fieldwork and research and can be accessed at the link below:

Additionally, Dr. Toor was announced a 2025 American Society of Agronomy (ASA) Fellow. To be named a Fellow is one of the highest honors ASA bestows and recognizes his outstanding contributions in the agronomy field and long-standing commitment to the profession.

ASA Fellows will be formally recognized at the 2025 CANVAS Awards Luncheon on November 10, in Salt Lake City, Utah.
