A strongly alkaline soil (pH 8.5 or higher) rich in sodium. It is found in many salt-accumulated lowlands in the dry climates of the temperate continental zone, and its soil type is called Solonetz soil. The lower layer is a dark, dense layer of accumulated clay and humus, and when it dries it shrinks and forms a characteristic columnar structure. Many plants cannot grow in this type of soil. To improve the soil, it is desalined by irrigating it heavily. It is not found in Japan. Source : Heibonsha Encyclopedia About MyPedia Information |
ナトリウムに富む強アルカリ性(pH8.5以上)の土壌。大陸温帯の乾燥気候下の塩類集積した低地に多く発達し,土壌型名はソロネッツ土。下層は粘土,腐植が集積し暗色で緻密(ちみつ),かわくと収縮して特徴的な柱状構造を示す。多くの植物は生育できない。土壌改良には多量の灌漑(かんがい)により脱塩化させる。日本には分布しない。
