- 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.
- Appraisal of World Reference Base for soil resources - from a nordic point of view
- Comparative study ; Cultivated land ; Denmark ; Europe ; Finland ; Human impact ; Northern Europe ; Norway ; Podsol ; Soil ; Soil classification ; Soil properties ; Sweden ; Taxonomy
- The WRB (World Reference Base for Soil Resources) classification of 13 different soils from Denmark, Finland, Norway and Sweden, is comparedwith the FAO and Soil Taxonomy classification. This highlighted some of the classification problems
- . This paper will propose changes to the WRB in order to improve the performance of the system for Nordic soils.
- Establishing the role of pedogenesis in changing soil hydraulic properties
- Chronosequence ; Pedogenesis ; Podzol ; Rill wash ; Scotland ; Slope dynamics ; Soil properties ; Soil water ; United Kingdom
- Chronosequences provide suitable sources for the study of changes in soil hydraulic behaviour as a result of long-term pedogenesis. For a podsol chronosequence in the Scottish Highlands, data are presented to indicate the changes that have occurred
- over 13 000 years in the saturated hydraulic conductivity in each horizon. As the soil profile has evolved into a differentiated sequence of three horizons, the resulting hydrological changes can be both measured and quantified. The results

- This paper aims to identify the spatial distribution of exchangeable base cations in soils on an acid hillslope, (Quantock Hills, Somerset, UK), and to investigate possible cation release processes from slope soils to the stream. The basic
- assumption underlying this research is that the amount of exchangeable cations in soils reflects the nutrient stores and cation leaching processes across the slope where vegetation and parent materials are similar.
- mainly podsolic soils have been developed on Pleistocene sands. The present day landscape and the usability of the soils for various agricultural activities have been described. (A.I.S.).
- The soils of an area in the centre of the province Friesland have been described. Extensive areas consist of peat soils, in the northwestern part of the sheet an area developed on Holocene sea clay deposits is found, in the southern and eastern part

- In 1990 FAO published a revised legend to Soil Map of the World (FAO-UNESCO 1990). In order to harmonize the soil maps of Europe, it is necessary to transform the EC soil map using the 1985-nomenclature to the FAO revised legend of 1990. This paper
- describes the construction of a Danish soil ap at scale 1:1000000 using the FAO 1990 legend.

Land-use legacies and soil development in semi-natural ecosystems in the marginal uplands of Ireland
- Land-use legacies and soil development in semi-natural ecosystems in the marginal uplands of Ireland
- Forest ; Forest fire ; Ireland ; Land use ; Oak ; Palynology ; Pedogenesis ; Pine ; Podsol ; Quaternary ; Soil ; Soil properties ; Vegetation dynamics
- The relationships between semi-natural oak woodlands and the podzolic nature of their soils were investigated at 14 wooded and nine non-wooded sites located in otherwise similar environments in Ireland. Historical records and palynological data were
- used to evaluate vegetation-soil dynamics and land-use history for both site types.

- This study was conducted to evaluate the potential of SEM/EDS analysis (scanning electron microscopy/energy dispersive spectrometry) to fingerprint two types of topsoil in a research basin: a black, chernozemic, farmland soil and a grey, podzolic
- , forest soil. The two simulated suspended sediment samples were similar in particle size distribution, mineralogy, and total chemistry, but an important difference was the morphology of the clay class particles, consisting of water-stable clay aggregates.

- The AA. present a detailed thermoluminescence chronology of soil horizons from 11 late Quaternary coastal aeolian and barrier sedimentary sequencies along a 900 km stretch of coast in south-east Australia. The results show that in the majority
- of cases the A and B horizons of what appear to be typical intact podzol profiles have widely disparate ages. The AA. suggest that these soil profiles have been subject to reworking. Although these soils give the appearance of being intact, they are in fact
