Short summary
Our paper highlights the importance of dual-nutrient management: nitrogen (N) and phosphorus (P) in lakes with cyanobacterial harmful algal blooms. Taihu Lake (China) experiences seasonal blooms due to increased input of N and P from field runoff. The main process investigated in our study, nitrification, is important for N removal through denitrification. We show that nitrification is less efficient during the blooms, due to competition for nutrients between N microbes and cyanobacteria.
