Minimizing phosphorus transport from paddy fields by innovating irrigation-drainage regime for southern region of the Taihu Basin
南太湖区域水浆管理技术与稻田磷素流失控制的研究

A field experiment to elucidate the interception of phosphorus (P) export during a typical rice-growing season was conducted in the southern region of the Taihu Basin in China. Phosphorus export was measured for both traditional and water-saving irrigation-drainage regimes after application of superphosphate. P concentrations in floodwater rapidly declined after the application of P fertilizer, and subsequently returned to the background levels. The traditional irrigation-drainage scheme and the water-savin...
