Congress ; Soil ; Soil classification ; Soil properties ; Soil science ; Taxonomy
The A. presents the meeting and its objective: to discuss the various concepts of soil horizons and the role that soil horizons play in soil characterization, classification and mapping. This number of Catena contains selected papers of this meeting.

Some remarks on soil horizon classes

Some remarks on soil horizon classes
Soil horizons
Soil ; Soil classification ; Soil properties ; Soil science ; Taxonomy
Soil horizons are the results of pedological processes and classes of soil horizon descriptions are seen as fundamental to soil classification. A fuzzy-sets approach to horizon classes is suggested to deal with the intergrading and multivariate
nature of soil horizons.

Pedological regional variations in well-drained soils, Denmark

Pedological regional variations in well-drained soils, Denmark
Denmark ; Pedogenesis ; Soil ; Soil classification;Classification of soils ; Soil properties ; Spatial variation ; Statistics
Soil profile investigations were carried out within a national 7 km grid. The profiles were classified according to the 1974 FAO-Unesco Soil Classification System. This paper describes the regional variations in soil profile development
and the related dominant soil formation processes.

The Soil Conservation Service of New South Wales (Australia) is mapping soil landscapes at a scale of 1:100,000 and is using a soil layer based entity, termed soil materials, as the basic entity for soil description and classification. This paper

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, brown soils, 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 brown soils, chernozems, earthy barren grounds, hydromorphous soils). Surfaces are classified according
to the extent of soil loss.

Degradation of soil structure by welding. A micromorphological study

Degradation of soil structure by welding. A micromorphological study
Agricultural practice ; Agropedology ; Limburg ; Loess ; Micromorphology ; Netherlands (The) ; Soil ; Soil erosion ; Soil properties ; Splash
In 1985 a plot study was started on sloping cultivated loess soils in South-Limbourg (The Netherlands) to evaluate the effects of various cropping systems of fodder maize on runoff, soil loss and crop yield under natural rainfall. In 1988
, in addition a soil micromorphological investigation was undertaken of the soil layer at and immediately below the soil surface on the experimental plots. In this paper the results of the micromorphological analysis of the processes of soil structure
degradation and crust formation are presented including the applicability of the McIntyre model of soil crust formation.

Soil science reference books

Soil science reference books
Bibliography ; Soil ; Soil classification ; Soil properties ; Soil science ; Textbook
This paper focuses on the 7 major soil reference books that were published between 2000 and 2012 : Handbook of Soil Science (2000 and 2012), Encyclopedia of Soil Science (2002 and 2006), Encyclopedia of Soils in the Environment (2005), Encyclopedia
of Soil Science (2008), and Soil Science — Reference collection (2009). These soils science reference books contain 1920 articles authored by some 2000 authors. The Handbook of Soil Science covers the basic subdisciplines (physics, chemistry, biology
, pedology) most extensively whereas the encyclopedia have more applied entries/articles. Overall, these intradisciplinary reference works show that the soil science discipline is vibrant and has a rapidly expanding knowledge base.

Fire impacts on soil nutrients and soil erosion in a Mediterranean pine forest plantation

Fire impacts on soil nutrients and soil erosion in a Mediterranean pine forest plantation
Ecosystem ; Fire ; Forest ; Israel ; Rill wash;Runoff ; Soil ; Soil erosion ; Soil properties ; Soil science
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
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.

Soil horizon use by the U.S. soil survey

Soil horizons
Concept ; Soil ; Soil classification ; Soil properties ; Soil science ; Taxonomy ; United States
There are many more possibilities for designating horizons and layers in field descriptions than there are when applying the defined diagnostic horizons that are used in Soil Taxonomy. The first set are based on qualitative judgements, the latter
are based on quantitative measurements. The Soil Survey in the United States has found it useful to keep the two kinds of horizon designations separate.

Detachment of soil particles by shallow flow : sampling methodology and observations

Detachment of soil particles by shallow flow : sampling methodology and observations
Erodibility ; Grain size distribution ; Methodology ; Precipitation ; Rill wash ; Sampling ; Sediment budget ; Soil ; Soil erosion ; Soil properties ; Splash
This study compares several methodologies for conducting flow detachment tests. Particularly, differences in initial soil moisture conditions and soil surface characteristics due to the combined effects of various types of crops and applied raindrop
kinetic energy caused differences in soil detachability by overland flow. Furthermore, soil sampling in different periods of the year resulted in variations in soil detachment indicating a seasonal trend in soil detachability.

Farmer perception of soils in the mountains of the Dominican Republic

Farmer perception of soils in the mountains of the Dominican Republic
Dominican Republic ; Environmental perception ; Perception ; Rural geography ; Soil ; Soil conservation ; Soil erosion
In Las Cuevas north of Azua 80 farmers were interviewed about their soils : 48% of them were aware of soil erosion, but had little interest in soil conservation. None of the farmers named more than six kinds of soil. Stoniness or soil depth were
not considered by them to be important in defining soil quality. - (DWG)

Soil erosion and soil structure in Impact of water and external forces on soil structure. Selected papers of the 1st Workshop on soilphysics and soilmechanics, Hannover 1986.
Recent studies show that measured soil losses due to water erosion differ significantly from estimated values using nomographs derived from loess soils. Under identical environmental conditions these deviations seem to be caused by the parent
material affecting soil structure. The final questions show that research on the interaction between soil loss and soil structure needs to be forced.
