Scientists Apply Amended Soils to Control Agricultural Non-point Source Pollution in Small Watershed

Prof. CHEN Jingan's research team from IGCAS applied natural zeolite (NZ), aluminum modified clay (AMC) and lanthanum modified bentonite (LaMB) to improve the natural soil in the lakeside zone of a typical small watershed (Kelan reservoir) in Guangxi, China. They studied the dissolved inorganic P (DIP) and ammonia nitrogen removal efficiency and fixation mechanism of three amended soils under simulation conditions.
