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, brown forest soils 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 (brown forest soils, chernozem brownsoils, chernozems, earthy barren grounds, hydromorphous soils). Surfaces are classified according
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
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.
Geografia pôd Vysokych Tatier a ich predpolia. (The soil geography of the High Tatra Mts. and their foreland)
The soils of the area consist of the podzols, rankers, rendzinas (alpine subtypes), pseudogleys and brownsoils. The vertical soil zonality in the crystalline and mezozoian oart is presented as well. (MS).

-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
Effects of prolonged irrigation on the humus of steppe soils in southwest Siberia
Records in soils of environmental and anthropogenic changes
Asian part of Russia ; Humus ; Irrigation ; Soil ; Soil moisture ; Soil properties ; Steppe ; West Siberia
Changes in humus resulting from up to 20 years'irrigation with slightly saline water were studied in dry steppe soils in southwest Siberia. The amounts of brown humic acids and of the Pg fraction increased with the period of irrigation
, and their maximum amounts occurred at greater depths in the profile. Other fractions of humus and humic acids fluctuated within the limits typical of dry steppe soils. The humus therefore remained essentially stable under irrigation for up to 20 years.

The objectives of this paper are to: i) describe the types of gelatinous, red-brown, iron-rich precipitates found in waterlogged surface layers of recently-formed, saline, sulfidic soils and compare these precipitates with those that befoul
boreholes in the same area and ii) elucidate the biogeochemical processes of iron mineral formation in both the gelatinous red-brown iron-rich precipitates formed during the wet season and yellowish iron-rich crusts formed in the dry season.
Bergbaubedingte Veränderungen des physischen Nutzungspotentials dargestellt am Beispiel des linksrheinischen Braunkohlreviers. (Changes of the natural potential resulting from mining on the example of the Rhenish Brown Coal Field)
The purpose of the study is to analyse the changes resulting from the mining of brown coal. The study examines the natural potential of the sample areas before the extraction of the brown coal and after the recultivation, and it evaluates
or deteriorations of the land potential differenciated according to the components soil, landform, and local climate. (l'A.).
Rates and mechanisms of discontinuous gully erosion in a red-brown earth catchment, New South Wales, Australia
was episodic depending on pipe development, cracking, and soil detachment during small runoff events which prepared the heads for rapid soil movement by the infrequent large event.
In the years 1985 and 1988 soil chemical parameters have been analysed for shallow layered rendzinas on slopes and brown clay soils formed in the bottom of valleys and dolines. Within the three years the measurements of pH (KCl) show an obvious
change towards to acid conditions. Nitrogen- and sulphur-enrichment took place in the top layer of the soils. The supply of nutrients decrease, but they are still sufficient available. The decrease in trace elements correlate with the decrease in the pH

Unique features related to the genesis and classification of dry-steppe soils with an eluvial-illuvial differentiated profile on ancient weathering zones of the Tersek Plateau are discussed on the basis of detailed morphological descriptions

Studies of critical concentration distribution features of polluted elements of Cd and As in main soil types of China, such as laterite, yellow brownsoil, black soil and sierozem revealed that soil types vary in different zones, so do
their critical concentrations. The critical concentration has a zonal differentiation with the distribution of soil types from south to north and fromm east to west. This coincides with changes of climate zones and soil zones.
