| Abstract: | This paper put the focus on the realationship between nitrogen in surface soil and ammonia nitrogen in shallow groundwater.It is found that acidic-strongly acidic soils and Quaternary Holocene mudflat sediments which are high in Fe and Mn contents provided geochemical conditions for local pollution of ammonia nitrogen in shallow groundwater.And unreasonable application of nitrogen fertilizers would lead to long-term and vast-scale pollution. |
