The Effect of the Potamogeton crispus on Phosphorus Changes throughout Growth and Decomposition: A Comparison of Indoor and Outdoor Studies

Phosphorus (P) transport and transformation in water were investigated using Potamogeton crispus. To compare evaluate our indoor experiment with outdoor data, we used the simultaneous field observation approach. The effects of P. crispus growth decomposition on P concentrations investigated. significantly reduced content different forms during period, increased according to findings. As a result, level varied seasonally regularly. pH dissolved oxygen (DO) environmental factors revealed an increasing trend period negative period. changing chlorophyll (Chl-a) alkaline phosphatase activity (APA) was inverse, decreasing In environment, all positively related Chl-a, APA, pH, negatively DO. comparison data that number has larger standard deviation, indicating fluctuated substantially. simulation disadvantage large fluctuation. this study demonstrated regulated cycle via absorption changes released nutrients thereby influencing migration water. This work may be as reference for future research into process exchange between sediments interfaces caused by
