CHA, Jong Whan(Graduate School, Dong Kook University) The Soil properties of woodland having different geological origins. Kor. Jour. Bot. Ⅶ (3):15-21, 1964.
In this experiment, the chemical compenents of the soils were collected from different horizons in some forest soils and naked soils developed on granite, crystalline schist, and granite gneiss were ana1ized to be compared with each other.
The developed degree of the surface soils showed some difference according to the different geological formation. The soil derived from granite gneiss was showed to have more water content, available nitrogen, exchange properties and weathered most.
Much quantity of the organic matter, and of the available phosphorus was discovered in the soil derived from granite and found closely related to each other. The soil derived from the parent rock of granite showed highest acidity.
The soil derived on crystalline schist was found to have the maximum quantity of the nitrate nitrogen and the least of the exchange properties.
The only significant difference among the chemical properties of the three parent rock seems to be in the contents of the available phosphorus, nitrogen, water content, and organic matter in the Pinetum densiflorae, of the nitrogen, exchange properties, and pH in the Alnusetum japonicae, of the available phosphorus, nitrogen, total exchangeable base, and base saturation in the naked area, and of the nitrogen, base exhange capacity, and pH in all forest soils.
The degree of the distribution of the nutrient in soil was found decreasing going from the surface soil down to the subsoil.
