Struktura pudniho fondu v CSR. (Structure of soil fund in the Czech Socialist Republic)
A survey of soil fund structure in the CSR for the height soil zones of hydromorphic soils, chernozems, brownsoils, illimeric podzol soils, brownforestsoils and mountain podzol soils. (MS).
A Tolnai-dombsag genetikai talajtipusai és talajlepusztulasa. (Genetic soil types and soil erosion in the Tolna Hills)
The loess covered and minutely dissected hilly region of high relief is described by various soil types (brownforestsoils, chernozem brownsoils, chernozems, earthy barren grounds, hydromorphous soils). Surfaces are classified according

-order minerals) and if there is a relationship between pedogenesis and aspect and more recent landscape history. The morphology of the soils indicates brownsoils with only few signs of podsolisation. In contrast, selected chemical properties
of the soils reveal very strong weathering and leaching. The inclusion of these soils into the brownsoil order of the New Zealand soil classification is therefore somewhat misleading and does not ideally reflect their soil genesis and chemical properties
This study focuses on soils in a mountainous catchment area located in the eastern part of the Southern Alps, South Island, New Zealand. The aim was to check the soils for non- or poorly crystalline constituents (metal organic complexes, short-range
. It is proposed that the components and the podsolisation features are relicts caused by more acidic conditions under former forest cover which supported a stronger weathering and leaching.
The forestsoils developed in the sandy weathering material of the Liassic limy sandstones in southeastern Belgium have been mapped as argillic brown sands ore, more rarely, as podzolic soils. Chemical and mineralogical analyses make the author
to propose that the brownish or slightly podzolised profiles which are developed in the loessic sands of the Liassic cuesta, are the expression of the post-glacial forest pedogenesis, whereas the underlying argillic horizons are probably inherited from
Zum Spurenelementgehalt von Fichtenstandorten im Tharandter Wald und Osterzgebirge. (Trace element content of spruce sites in the Tharandt Forest and eastern part of Erzgebrige)
For forest sites situated on various basic rocks in the eastern parts of the Ore Mountains the total content of a greater number of trace elements in the mineral soil and A. horizon is reported. The values of the nutrient level K (eutrophic
) correspond approximately to the medium contents in soils predominantly used for agricultural purposes. Brown earths over olivine-nephelinite, gneiss, and phyllite are richer in trace elements than podzols over quartz porphyry. But even in the case of brown
earth rich in Cu and Zn and lying an olivine-nephelinite tolerable contents are not exceeded. The partially richer accumulation of Pb in the mineral soil of the Tharandt Forest is conditioned mainly by geological and petrographical factors
Climatic and pedoclimatic features of the areas of European sod-podzolic, lessivé and brownforestsoils are compared. The differences in quantitative pedoclimatic indices, the thermic ones especially, proved to be neteworthy. They account
for the heat reserves in soils and for the facies-provincial soil pattern. Basing on thermic criteria soils were subdivided at the subtype level. The differences between three soils as to their moistening and water reserves in annual and seasonal cycles were
revealed. (L'Ed.). Traduction anglaise dans Soviet soil science, 1981, 13, n 4, pp. 103-110.

The AA. calculated rainfall erosivity for future climates using new temperature threshold in the Southern Rockies Ecoregion (SRE). They used RUSLE to calculate soil loss for 16 future climate and wildfire scenarios and compared future soil loss
to results from historic runs. Based on 100 simulations of future wildfire applied to RUSLE for each global circuation model scenario combination, they found that soil loss will likely increase above historic levels but that considerable uncertainty remains

The humic brownsoils of the Papua New Guinea highlands : a reinterpretation
Developing on volcanic ash, these soils owe their distinctive appearance and properties to the nature of the soil parent material rather than climate. Not as fertile as once presumed, the soils are no longer capable of sustaining continuous cropping
frost and thaw cycles, include frost cracks, cryoturbations and creep or solifluction mass movements. Fossil soils are either gray brown podzolic soils developed under forest, or hummic steppic soils.
The genesis and the stratigraphical context of the periglacial phenomena and the fossil soils preserved into the Upper Pleistocene deposits at Maisières-Canal, Harmignies and Rocourt are discussed here| for most of them, it has been possible

Stone forest is a unique karst landform with a complex evolution process. This paper will focus on stone pillars, the basic component of stone forest, analyse different combinations of sub-aerial, soil, and sub-soil erosion in Lunan Stone Forest
area, and propose a Triplex erosion mechanism for stone forest evolution.
Effect of fire on soil, rice, weeds and forest regrowth in a rain forest zone (Côte d'Ivoire)

Forest, soil, rice, weeds and regrowth were studied in the fields off local farmers in permanent plots during 2-5 years. The fields covered all currently cultivated soil types and forest types. This study is concerned with the full shifting
wildfire at the end of summer 1988. The results suggest that light and moderate forest fires may increase soil fertility without cousing a marked difference in soil runoff and erosion.
Detailed measurements of soil nutrients, runoff and sediment discharge were made in two plots about 200 m2 each in a plantation of Aleppo and Brutia Pine in the Mediterranean climatic region of Israel. One of the plots was affected by a moderate
In this paper the solution profiles of an eluviated loamy soil and a podzolized sandy soil are presented, and the soil formation processes as reflected in the soil solutions are related to the models proposed by Ugolini.
