Uniformity of fertilization, change in the nitrogen concentration of flooded water and absorption of applied nitrogen by paddy rice were examined. High uniformity of fertilization was achieved with this method as compared with a conventional broadcast application of granular fertilizer, or an inflow fertilization of granule-like fertilizer with irrigation water. When urea was applied as liquid fertilizer, the fertilizer-N disappeared quickly from ponding water under shallow conditions of ponding water depth. In the case of the same depth of ponding water, the rate of reduction was large under conditions of large permeability of water. The nitrogen utilization rates of urea and ammonium sulfate labeled with ^\u003c15\u003eN were not related to the depth of ponding water at the time of fertilization. When ammonium sulfate was supplied the nitrogen utilization rate was around 50% regardless of fertilization conditions; however, the urea-N utilization rate fell to 40% or less at a permeability of ponding water of 0.8cm day^\u003c-1\u003e or less, while it increased to 50% equivalent to ammonium sulfate, at 0.8cm day^\u003c-1\u003e or more permeability.", "subitem_description_type":
