Luvisols are the dominant catchment soil type of the streams falling into Vortsjarv from the north, north-east, and west; podzols
prevail in the southern and southwestern catchment parts while regosols are represented with an appreciable proportion only in the Vaike Emajogi catchment (Fig.
These forests (called caatinga) form on white sand soils of extreme infertility, made up mainly of quartz podzols
Nevertheless, the survey samples showed that the water table levels were shallower than 50 cm in the floodplains, providing the necessary data for the hydrological soil group acquisition of the Podzols
, according to (Sartori et al.
Soils varied in classification and were derived mostly from the following Food and Agriculture Organization of the United Nations (FAO) soil units: Acrisols, Calcisols, Cambisols, Fcrralsols, Luvisols, Podzols
, Solonchaks, Solonetz and Vertosols.
According to Anderson (1963), most of the plant species that grow in the forests at the centre of the peat domes are mostly those that are usually found on nutrient poorer soils, such as podzols
of the heath forest (Anderson, 1963).
du haut rio Negro, region de Marao, Venezuela.
However, in the riparian soils the soil type ranges rather from gleyic podzols
Soils are observed to be generally shallow and include cryogenic mineral soils, poorly developed podzols
, and some hygric organic soils.
Loss of expandability of smectitic clays is often observed in the acidic upper horizons of soils developed under a cool humid climate, such as Podzols
and Brown forest soils, in Europe and North America (Wilson et al.
The only overlapping characteristics may be found for qualifiers albic and dystric, which are common for Albeluvisols (pseudopodzolic soils) and Epigleyic and Fibrihistic Podzols
), and luvic, which is common for Luvisols (lessive brown soils) and Albeluvisols.
The ablation moraine has a prevalence of cambisols, the ground moraine either cambi- or luvisols and the eolic accumulation plains mainly podzols
In general, the coastal plain is characterised by Quaternary hydromorphic Podzols
