Organic and inorganic nitrogen additions have similar effects on lake phytoplankton nutrient limitation

Experiments were conducted across the Northeastern US to evaluate the importance of nitrogen and phosphorus as limiting nutrients in a variety of lakes. Most lakes were co-limited by nitrogen and phosphorus. Oneida Lake was one of the few lakes with phosphorus as the primary limiting nutrient. Lakes with watersheds more dominated by agriculture and higher total dissolved nitrogen tended to show phosphorous-limited phytoplankton responses. A manuscript was accepted for Limnology and Oceanography in 2022.
