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.

我们证实，在屋顶花园土壤的情况下，土壤中的大量肥料成分已被雨水或灌溉完成后不久浸出。据估算，每平方米10 cm厚的薄层土床，降雨量或灌溉量为438 ~ 688升时，土壤中的大部分肥料成分即可达到。此外，在考察了每种土壤材料的肥料成分含量并明确了淋失原因后，发现树皮堆肥成分的淋失趋势最大。很明显，我们可以建造屋顶花园，减少肥料淋失，同时保持草坪的生长和质量，通过使用花园土壤组合物，不含树皮堆肥，如芦苇，泥炭藓和沸石的薄层土壤床的屋顶花园。
