Scientific Name & Composition
A particle size analysis of the soils indicates that the residual soil consists of mainly silt and clay (approximately 95%) and that soil textures are silty clay or silt clay loam. The soil colors of the residual soil are dark brown (7.5YR 3/4) through yellowish red (5YR 4/6). The pH of the residual soil ranges from 4.3 to 5.1. The major minerals of the parent rocks were quartz, biotite, chlorite, and plagioclase. The mineralogy of the sand fraction of the residual soil was quartz, biotite, muscovite and sanidine. [4]
Hwangto Korean History & Culture
Hwangto has a close connection with Korean Culture and history. Records of Hwangto can be found in Shan Hai Jing and China's classic geography book; The Annals of the Joseon Dynasty, which is listed on UNESCO's Memory of the World Programme.
