The Possibility of Growth of Plants for Building Covering on an Artificial Ground that is Thin and Extremely Light-Weight

Abstract

In order to expand the possibility of inplanting green foliage plants into the spaces where only artificial ground or soil is available, a series of experiments were conducted to find out how far such plants can grow in the artificial conditions with the soil that were much thinner and lighter than the natural ground.
The results indicate that trees with middle and low heights as well as turf grasses can satisfactorily grow on the artificial ground with the thickness less than a harf of what is said to be necessary, and even not using ordinary soils but a light-weight soil amendment matter only. Besides, the artificial ground conditions were able to support only one-tenth of load of those constructed with conventional methods.
