The classification of soil drainage is broadly defined based on internal soil drainage and permeability, as well as relationships with soil color mottles, the location of mottles, groundwater level, soil texture, parent material, and topography. In Korea, soil drainage classes are defined as ‘somewhat excessively drained,’ ‘well drained,’ ‘moderately well drained,’ ‘somewhat poorly drained,’ and ‘poorly drained.’ However, the classification criteria for ‘excessively drained’ and ‘somewhat excessively drained’ in Korea are currently not quantified, making them ambiguous. Therefore, this study aims to classify soil series distributed in Korea into drainage classes such as ‘excessively drained’ and ‘somewhat excessively drained’, which currently lack clear classification criteria. The study follows the Soil Survey Manual and proposes quantified classification criteria based on soil characteristics. According to the Soil Survey Manual, ‘somewhat excessively drained’ is defined as ‘water is removed very rapidly or rapidly, consisting of coarse-textured soil with very high saturated hydraulic conductivity or very shallow effective soil depth.’ Quantitatively, this is classified as coarse-textured soil (Clay < 15%, Silt < 30%, and Sand ≥ 70%) with very high or high saturated hydraulic conductivity or very shallow effective soil depth (< 25 cm). Based on these criteria, forest soils in Korea were classified, and it was confirmed that some forest soils were misclassified. The proposed quantitative criteria for drainage classes are expected to be widely utilized by researchers for direct classification, moving away from traditional reliance on survey experts. These criteria are also expected to contribute to field farming guidance and the development of soil management strategies. Furthermore, correcting misclassified soils is essential to improve the accuracy of soil suitability ratings for crops.
