Phosphorus accumulation in soil surface under Japanese lawngrass ( Zoysia j aponica Steud .) pasture
Much attention is paid to the pasture of Japanese lawngrass in Japan because it is maintained with saved labor and without tillage or fertilizer.To clarify the mechanism of such sustainable production, nutrient flow in the pasture has to be investigated.Kaneko et al.(in press) suggested that P might be accumulated from the deeper soil profile into the soil surface in the pasture of Japanese lawngrass.The aim of this study is a comparison of soil P distribution from soil surface to 1 m in depth between the places of Japanese lawngrass and the places of other sward characteristics in the same pasture.This comparison enables us to discuss the P accumulation into soil surface by Japanese lawngrass plant.
