AbstrAct:The uniqueness of limestone soil-forming substrate was assessed with respect to the classification of forest ecosystems. 50 soil profiles from the Bohemian Karst were studied and the results were confronted with previously published works from other karst areas. The evaluation of soil profiles was based on a macroscopic description, on the results of chemical and physicochemical analyses, and on a micromorphological study. The carbonate bedrock was a cause of specific genesis of soils in these sites -both recent and relict ones (terrae calcis). However, it does not always condition the unique characteristics of these sites whose differentiation would call for an a priori special edaphic category. Unique geochemical characteristics of the substrate are modified on the gradient of advanced pedogenesis (Holocene up to mid-Pleistocene soils were assessed) by a very intensive soil-forming process connected with the impact of allochthonous, mostly aeolian material. Two possible approaches were designed for the classification of these sites: (i) wider conception -distinction of the basic edaphic category with small limitations for the quality of soil-forming substrate, (ii) narrower conception -limestone edaphic category with a number of limitations to distinguish this edaphic category.

“…These are Red Latosols, Red Podzols, Red desert soils and Red Mediterranean soils. The latter are termed Terra Rossa when they develop over limestones (Bronger and Bruhn-Lobin, 1997) and are usually seen in the coastal Mediterranean region where they are characterized by a red to brick red colour, which owes its origin to the presence of hematite (Yaalon, 1997). However, the climatic regimes are different from Saurashtra and hence the red beds may best be referred to as Terra Rossa-like soils.…”

“…These have been termed Terra Rossa and appear to be typical of Mediterranean regions, which experience rainfall during the winter months. Terra Rossa soils are currently understood to have formed by leaching and residual accumulation of limestone (Bronger and Bruhn-Lobin, 1997) although alternative hypotheses that propose Saharan dust addition exist (Herwitz et al, 1996). Late Quaternary aeolianites occur along the coast of Saurashtra in western India.…”

“…The latter, however, may contribute only partially, or not at all, to the soil parent material. Although some authors have assumed an origin of Terra Rossa from the residual material of limestone dissolution (Bronger and Bruhn-Lobin, 1997;Nagatsuka and Maejima, 2002), many others stress the importance of aeolian depositions (Olson et al, 1980;Yaalon, 1997;Delgado et al, 2003) as the amount of the limestone insoluble residue is often low and cannot produce the actual thickness of many Terrae Rossae. Aeolian deposition can be composed of Sahara dust (Nihlen and Olsson, 1995;Frumkin and Stein, 2004), loess (Durn et al, 1999), or volcanic ashes (Jackson et al, 1982).…”

Pedostratigraphic levels (PLs) are typical assemblages of soil-genetic horizons, formed by materials having the same degree of weathering. The pedostratigraphic approach can be very useful to comprehend the formation of the Quaternary soil cover, the environmental evolution of a territory, and to estimate the age of paleosols. A pedostratigraphic study of a Terra Rossa was carried out to understand the soil-parent material origin and to estimate the time of the beginning of pedogenesis. Besides soil and geomorphological survey, the Terra Rossa was analyzed for Fe forms, geochemistry, clay mineralogy, micromorphology, and with scanning electron microscope. Optical dating was applied to obtain age estimates for the deposition of the parent material of soil formation. The insoluble residue of limestone was obtained and analyzed for geochemistry and clay mineralogy. The bedrock is constituted by Quaternary lacustrine limestone, showing pronounced karst landforms. The soil profile is situated in a little dissolution doline and was divided into three PLs: PL1 (0-110 cm) is constituted by cambic and ochric horizons, formed during Holocene in a mixture of colluvial soil sediments and fresh limestone, with aeolian components; PL2 (110-290 cm) includes two argic horizons, which began to form during Late-Middle Pleistocene in colluvial soil sediments, with few aeolian additions; PL3 (290-330 cm) is constituted by a red argic horizon, with nitic properties, which developed from the insoluble residue of the limestone. The age of PL3 was calculated through a mass balance and an estimation of the limestone-dissolution rate during the Quaternary, which led to an approximate age of Middle Pleistocene, between 250 and 500 ky BP. The time of the beginning of pedogenesis on limestone can be used as a reference for the tectonic uplifting of the area and emersion of the plateau.
