%X <p>By analysing main factors affecting the migration and conversion of ammonia-nitrite-nitrates in groundwater, we aim to provide theoretical basis for the prevention and control of agricultural non-point source nitrogenous pollution. Qianyanzhou test station in Jiangxi Province was selected as research object and experiment plots were divided. The groundwater table, ammonia-nitrite-nitrates, ferrum-manganese and pH value of groundwater in the research area were monitored in long term. Through data sorting, diagram analysis and SPSS software, we analysed the correlation among ammonia-nitrite-nitrates, total iron, manganese in filtering state and pH value. Results suggest that the groundwater in the study area has been affected by agricultural non-point nitrogenous pollution. Ferro-manganese in groundwater are apparently associated. Ammonium nitrogen and nitrite nitrogen are positively related with ferro-manganese. Total iron, manganese in filtering state, pH value, temperature and rainfall are the main impact factors of the transport and transformation of ammonia-nitrite-nitrates in the groundwater.</p>
