| Summary: | Anthropogenically disturbed soils have unique properties. In most of the ecosystems, especially under disturbed soil
conditions, the soil properties are controlled by the accumulated materials. However, the equilibrium between the already
present soil mass and the accumulated soil mass is very fragile and is affected by many factors. There are diversity of views
about their identification and interpretations. This paper reports on the physico-chemical properties of the investigated
sites under different texture soil accumulate. Three sites namely Chung-nam university field (Site-I), Chung-buk Geosan
(Site-II) and Yong-in (Site-III) were investigated for diversity in physico-chemical properties. In situ and ex situ physical
and chemical properties were determined and comparisons were made for soil profiles examined at three sites. The
classification of disturbed soils largely depends upon the system followed for classification. The objectives of this paper
were to compare the properties of the disturbed soils and to classify for further research investigations of such soils.
Abrupt change in electrical conductivity at Site-III was recorded ranged between 10.7 dS m–1 and 1.1 dS m–1 below 20
cm depth. Sudden and abrupt changes in infiltration rates at all sites were also calculated. The data suggested that the
soil texture of the accumulated soil had also affected the properties of the underlying soil. Apparently, the difference in
the properties seems to be the result of overlying soil accumulates with different texture. The disturbed soils need to be
studied in detail and groupings be made on the basis of genesis and similarities. |
