A “patchwork quilt” of soils from South Korea
A "patchwork quilt" of 324 soil profiles from the Abgog to Yuwon soil series composed of images from the NAS (National Institute of Agricultural Sciences), Republic of Korea (naas.go.kr/english/)
The National Institute of Agricultural Sciences seeks to enable the general public including farmers to gain access to soil information easily by providing information on the attributes of soils and soil test information covering individual areas.
When described, using the Soil Taxonomy of the USDA, soils in Korea are classified into seven Soil Orders which are then further divided into 16 Sub-Orders according to soil moisture regime. Among those seven Soil Orders, the younger soils, Entisols and Inceptisols, are dominant. Entisols are the youngest soils, followed by Inceptisols. Alfisols and Ultisols are relatively older soils. The working unit of soil classification is Soil Series. Currently, over 400 soil series have been identified in South Korea.
Soil series are a level of classification in the USDA Soil Taxonomy classification system hierarchy. The actual object of classification is the so-called soil individual, or pedon. Soil series consist of pedons that are grouped together because of their similar pedogenesis, soil chemistry, and physical properties. More specifically, each series consists of pedons having soil horizons that are similar in soil color, soil texture, soil structure, soil pH, consistence, mineral and chemical composition, and arrangement in the soil profile. These result in soils which perform similarly for land use purposes.
The soil series concept was originally introduced in 1903. Soil series were originally intended to consist of groups of soils which were thought to be the same in origin but different in texture. Soils were thought to be alike in origin if they were derived from the same kind of rocks or if they were derived in sediments derived from the same kind of rocks and deposited at the same time.
A soil series name generally is derived from a town or landmark in or near the area where the soil series was first recognized. For example, the Haugan Series in the U.S. was first identified near Haugan, Montana. The distribution of a given series is not necessarily restricted to the boundaries of only one county or state—for example, the Hagerstown Series was first described near Hagerstown, Maryland, but has also been found as far away as Tennessee and Kentucky.
