Purpose: Sediment internal nutrient loading plays an important role in algal blooms. Thus, understanding the specific characteristics of nutrient (nitrogen (N) and phosphorus (P)) recycling from sediment is important for clarifying the processes and mechanisms of cyanobacterial growth and succession. Materials and methods: Sediments and water samples were collected monthly from five sampling sites in Lake Chaohu for 1year. N and P concentrations in surface and interstitial water were determined, and fractions of sediment organic matter, P, and ...
