| 内容記述 | The fate of polyolefin ^<15>N coated urea (POCU S-100) in a nursery box for the no-tillage transplanting system as compared with ^<15>N ammonium sulfate (AS) in the conventional tillage system had been investigated in light clay alluvial soil, sandy loam alluvial soil, and clay loam soil (Andisol) in 1994 and 1995. Rice (Oryza sativa L. cv. Hitomebore) was used as the test plant. The nitrogen concentration of the leaf blade of the rice plant in the no-tillage without rice straw (NT) and no-tillage with rice straw (NTS) treatments tended to be greater than those of the conventional tillage with rice straw (CTS) treatments in all types of soil at all growth stages, and there was no definite increasing or decreasing tendency in the N concentration of the leaf sheath and stem, and panicles of the rice plant among the treatments in all types of soil. Nitrogen recoveries from POCU S100 in the NT and the NTS systems were 77-79% and 78-83%, 61-73% and 66-78%, and 74-76% and 80-81% for light clay soil, sandy loam soil and clay loam soil, respectively, which is around 65.5-96% of the nitrogen released from POCU S100. Thus, this could reduce the environmental pollution. The straw application in the NT system increased the N recovery of POCU S-100 by 1-5%. On the other hand, nitrogen recoveries from ammonium sulfate applied as basal fertilizer in the CTS system were 35-43%, 20-29% and 23-32% for light clay soil, sandy loam soil and clay loam soil, respectively. Whereas those applied as a top dressing were 50-83%, 49-73% and 40-65%. Nitrogen uptake by the rice plant in the NT system was relatively higher than that in the CT system. The uptake of soil nitrogen by the rice plant in the NT system was lower than that in the CT system. | |||||
