The Effect of the Moulding of the “Masa” Soil on the Growth of Five Kinds of Planting trees at a Refuse Reclaimed Land in the Osaka Bay

Abstract

An experiment was performed in the growth of five kinds of planting trees for three years at a refuse reclaimed land in the Osaka Bay. These trees were planted in moulding “Masa” soil of 0.5m, 1m and 1.5m thick, and the clasher-run stone layer or the plastic sheet was laid at the bottom of moulded soil for stoping that methane soaked into the soil at a part of the experiment area.
As the result, trees which were planted on 0.5m thick soil grew less than on 1m and 1.5m thick.
