ZHANG Li-juan, MA You-hua, SHI Ying-yao, et al. Effects of Irrigation and Fertilization on Nitrogen and Phosphorus Runoff from Paddy Field[J]. 2011, 25(6).DOI:
The article explored the influence of nitrogen fertilizer application with several times under different irrigation modes on nitrogen and phosphorus loss in paddy fields under field experiment condition.The results indicated that the runoff of total nitrogen and phosphorus was between 4.41~17.85 kg/hm2 and 0.28~0.44 kg/hm2 under different fertilizer treatments with traditional irrigation respectively.The loss percentage of nitrogen and phosphorus fertilizer was respectively about 3.2% and 0.17%.Compared to ...
