Abstract
We examined the annual change in rooftop garden thin substratum light soil turfed (Zoysia matrella Merr.). There were no annual change about growth of the turf and physical properties of soil. Soil organic matter tended to increase and fertilizer components were equal to average level in golf field soil. Unused soil was significantly higher than the others and decrease with age. Fertilizer component showed no significant differences by with or without addition of fertilization. Therefore, we concluded that we have to cultivate turf by use of how to be better suited for rooftop garden.
