Research Abstract

We confirmed that a large amount of fertilizer components in soil has been leached by rainfall or irrigation soon after completion in the case of the soil for rooftop garden. It was estimated that most of the fertilizer components in soil could be reached by 438 to 688 liters of rainfall or irrigation for one square meter of thin layer soil bed with 10 cm thickness. In addition, it was found that the components of bark compost had the tendency to be leached most after we examined the amounts of fertilizer components for each soil material and specified the cause of leaching. It became clear that we could construct rooftop gardens with less fertilizer leaching while maintaining growth and quality of the turf by using garden soil composition which did not contain bark compost such as perlite, peat moss and zeolite for thin layer soil bed of rooftop garden.
