Abstract:

To study the characteristics of pedogenesis and types attribution of soils in Yongnian District of Handan City, the 3rd National Soil Survey was carried out in the district in 2022. A total of 616 surface soil samples and 20 soil profiles were collected, 6 typical soil profiles were selected as the study subjects, and the position of each soil body in the Keys to Chinese Soil Taxonomy (CST) was determined through the analysis of soil profile morphological characteristics and physical and chemical properties. According to the classification search results of CST, it was found that the diagnostic layers in the test profile included ochric epipedon, cambic horizon, and argic horizon, and the diagnostic features included redoxic features, calcaric property, lithologic characters, soil temperature regimes, and soil moisture regimes. In CST, the studied soils were belonged to 3 orders of primosols, argosols, and cambosols, 4 suborders, 4 groups and 4 subgroups; meanwhile, 5 soil families and 6 soil series (Zhaili series, Jiyao series, etc.) were established of the selected soil profiles. The reference between pedogenesis and system classification of 6 soils profiles was conducted from high and base taxon. It provides a precedent for carrying out the soil survey and soil system classification work in Handan City.
