This study aims to investigate the long-term effects of rice cultivation on soil organic nitrogen dynamics. Rice is an important food crop worldwide. Its cultivation has a significant impact on soil ecosystems, especially on the dynamic changes of soil organic nitrogen. By reviewing existing literature, the changes in soil organic nitrogen content under different planting years and management measures were analyzed to reveal the effects of rice cultivation on soil health. This study found that long-term rice cultivation may lead to fluctuations in soil organic nitrogen content and affect the physical and chemical properties of the soil. Seasonal and interannual changes, agricultural management practices (such as fertilization and crop rotation) and other factors play an important role in the dynamic changes of organic nitrogen. This study provides new insights into the understanding of the soil nitrogen cycle mechanism and proposes a scientific basis for sustainable agricultural management. Through reasonable agricultural management measures, such as the use of organic fertilizers and green manures and the optimization of flooding management in rice fields, soil health can be improved, the stability and availability of soil organic nitrogen can be enhanced, and rice yield and ecological environment protection can be promoted.
