Study on the Release of Nutrient Salt from Soil in Baiyangdian Area
Abstract
As a national key protection and restoration project, Baiyangdian has an important and far-reaching significance. As one of Baiyangdian's lakes, Zaozhadian needs to adapt to local conditions and adopt a near-natural method of "returning farmland to wetland" for treatment and restoration. According to the difference of total nitrogen (TN) and total phosphorus (TP) content in the soil, soil nutrient release experiments were conducted to explore the effect of soil nutrient release on the quality of overlying water. The results showed that the amount of nutrients released was different in different soils, the total nitrogen release range was 0.19-0.77 mg/L, the total phosphorus release range was 0.03-0.4 mg/L, and the ammoniacal nitrogen release range was 0.16-0.34 mg/L.
