内容 東京湾沿岸における海底浚泄土によって造成された土地の土壌の物理的, 化学的性質について調査, 分析を行なった.その結果, 1.土地造成のために用いられた浚泄土壌は地下90cmまでは砂土である.2.川崎, 市川地区では土壌断面に粘土の層が見られ, 稲毛地区より姉崎地区にかけては見られず, 同じ浚泄方法で埋立てられた土地であっても土壌断面は決して一様でない.3.土壌中における塩素は自然状態でも比較的速やかで, 埋立後約4年経てば造園植物材料に影響しないであろう.4.土壌pHはその殆んどが7.6〜9.1を示すアルカリ性であり, 置換性塩基は決して一様の状態でないがK_2O, CaOが目立っている.
On the Soil of Land Reclaimed by Dredged Soil from Sea-bottom in Tokyo Bay. T. ANBIRU. Faculty of Horticulture, Chiba University, Matsudo, Japan. Tech. Bull. Hort. Chiba Univ., No.14, 77-81, 1966. Nowadays, reclamation of land by dredging sea-bottom soil along the coast of Tokyo Bay has become popular. In this connection, the author has been conducting the surveys of the reclaimed soil to determine its suitability to trees and shrubs. The results obtainted are as follows. 1) As a result of mechanical analysis of the soil it was found that the soil of reclaimed land was sandy. 2) Vertical section of the soil revealed that it was mostly made up by sand. In the case of the soil near the mouth of river, however, it consisted of thin clayey soil layers alternating with sandy layers. 3) It was shown that salt in the soil was easily leached away at a relatively rapid rate. This fact suggests that salt in the soil will have no detrimental effect on the growth of trees in a few years. 4) With a few exceptions, soil pH was 7.6 to 9.1, indicating alkaline soil and main exchangeable bases were K_2O and CaO.
