By regulating the global nitrogen cycle<\/strong>, wetland ecosystems help reduce nitrogen dispersion<\/a> and, consequently, soil eutrophication and water pollution<\/strong>. Contributing to this reduction is plant biodiversity, which impacts the retention and removal of nitrogen. This is according to researchers from the Chinese Academy of Sciences<\/strong> in a study<\/a> conducted at the Wuhan Botanical Garden. Here, they explain, greater plant diversity has increased soil nitrogen and dissolved organic carbon levels over time, while reducing the level of nitrates.<\/p>\n
