The remodeling agricultural land in South Korea is an anthropogenic soils created by reclaimed dredging generated from the Four Major River Restoration Project. The area of ​​the remodeled agricultural land is 7,727 ha, and many of the area are located near the Four Major Rivers. Soils made artificially by human activities differ from natural soil in terms of development as well as soil properties. Thus, this study attempted to classify the soil of the remodeled agricultural land using 3 soil classification system 1) Soil Taxonomy, 2) WRB (2014), 3) WRB (2022). Inchang series, a remodeled agricultural land, is fine, mesic family of Anthroportic Udorthents for Soil Taxonomy. WRB (2014) is recognized as Spolic Urbic Technosols (Siltic, Anthraquic, Gleyic, Transportic) and WRB (2022) is classified as Stagnic Gleyic Spolic Urbic Technosols (Siltic, Anthraquic, Transportic). Soil Taxonomy is limited in understanding soil properties because it categorizes anthropogenic soils into subgroups. On the other hand, WRB classifies anthropogenic soils into Anthrosols and Technosols into RSG, and continuously revises the classification system for accurate classification of anthropogenic soils. Therefore, it is necessary to revise classification of Korean soils according to the revised classification system for accurate soil classification. Furthermore, for soil classification suitable for Korean soil, it is necessary to create a soil classification system by referring to the WRB as well as Soil Taxonomy.

Results of classification of Inchang series using Soil Taxonomy (2014), WRB (2014) and WRB (2022) are fine, mesic family of Anthroportic Udorthent, Spolic Urbic Technosols (Siltic, Anthraquic, Gleyic, Transportic) and Stagnic Gleyic Spolic Urbic Technosols (Siltic, Anthraquic, Transportic).
