Abstract: Four in-situ experiments were conducted to investigate the runoff loss characteristic of nitrogen and phosphorus in typical rice fields in Guangdong province, South China under the condition of natural rainfall. The results showed that conventional-fertilization treatment (F) affected insignifcantly (p > 0.05) the runoff loss of phosphorus in comparison with F0. The majority of formation of phosphorus runoff loss was particulate phosphorus (pp).
