Abstract. Equatorial podzols are soils characterized by thick sandy horizons overlying more clayey horizons. Organic matter produced in the topsoil is transferred in depth through the sandy horizons and accumulate at the transition, at a depth varying from 1 to more than 3 m, forming deep horizons rich in organic matter (Bh horizons). Although they cover great surfaces in the equatorial zone, these soils are still poorly known. Studying podzols from Amazonia, we found out that the deep Bh horizons in poorly drained podzol areas have a thickness higher than 1 m and store unexpected amounts of c

Abstract Atotal of 212 soil profiles were described and assessed for physical and chemical properties during July 2006 as part of an Ecological Land Classification study along the Churchill River in central Labrador. Two major soil types were found in the study area along the Churchill River: Podzols and Organic soils. Podzolic soils covered approximately 60% and Organic soils occurred in 24% of the study area. Approximately 15% of the study area was classified as rock and other unconsolidated material. Summary results and a sub−set of the following soil units (from 10 soil profiles) are prese

Abstract:

In recent years, the number and intensity of forest fires has increased and thus more attention is paid to studying the pyrogenic soils. Parameters under study include, the post-fire return of phosphorus, alkali and alkaline earth metals, etc. from burnt plants and forest floor to the soil, but the related dynamics of iron and aluminum compounds has been poorly studied. However, these two elements are crucial for soil-forming processes and the productivity of many soils, in particular of the podzols under the most fire-hazardous pine forests in dry habitats.

Soil solutions from an Orthic Ferro-Humic Podzol and a Typic Humisol were extracted using a soil to solution ratio of 1:10 by the batch and column procedures. The aluminum speciation in the extracts was determined by measuring three forms of dissolved aluminum (uncomplexed monomeric, total monomeric and total reactive). The two methods of extraction gave different results. For most of the mineral horizons and the moderately to well-decomposed organic horizons the batch method tended to extract more dissolved aluminum, particularly in uncomplexed monomeric form.

Abstract. Podzol-ferralsol soil systems cover great areas in Amazonia and in other equatorial regions, they are an end-member of old equatorial landscape evolution, are frequently associated with kaolin deposits and store and export large amounts of carbon. Their biogeochemistry was usually inferred from soil mineralogy and from spring or river water properties. This paper presents a database for groundwaters sampled in situ in a typical podzol-ferralsol soil catena from the Alto Rio Negro region, Brazil; the sampling periods allowed to sample under high- and low-level water-table conditions.

AbstractTwo soils, a haplic Podzol and a dystric Cambisol, developed from post-glacial tills, were studied with respect to their soil chemistry and clay mineralogy. Although the state factors (age, geology, topography, climate) of soil formation were almost identical, two different types developed. The E horizon of the Podzol contained more smectite, characterized by a montmorillonite-beidellitemixed phase. The neoformation of smectite could be traced back to the weathering of mica and chlorite. The Podzol had less hydroxy-interlayered smectite (HIS) in the surface horizons than the Cambisol.

Calcareous sands (Fluvisols/Regosols) and Podzol soils of at least seven different ages (0, 2500, 3000, 5000, 5800, 6200 and 6500 calendar years) form a soil chronosequence in the prograded beach-ridge plain near Moruya Heads, on the south coast of New South Wales. Ages of the soils were determined by radiocarbon dating of marine shell deposited with the sediment. The soils range from undifferentiated quartz sand mixed with marine shell debris at the youngest site, to well developed podzols with pronounced AI, A2 and iron-humus B horizons at the oldest sites. Age trends are evident in a range

Abstract:

Four Bf and one Bhf Podzol horizon samples from the Precambrian Shield, Ontario, Canada were leached with pH 3 solutions in three different experiments to determine which soil aluminum fraction was primarily responsible for the aluminum leached into solution. For the Bf horizons, it was primarily the oxalate-extractable aluminum fraction (corrected for pyrophosphate, Alo–Alp); for the Bhf horizon it was equally the pyrophosphate (Alp) and Alo–Alp. A comparison with other studies suggests that when the ratio (Alo–Alp)/Alp is above 0.3–0.7, the oxalate-extractable fraction will be most important

A chronosequence of sandy soils was investigated on four terraces near Lake Michigan to assess rates of podzolization and changes in soil properties with age. The terraces ranged in age from 3000 to 10 000 BP. Each surface was systematically sampled to determine the modal profile, which was then described and sampled. Quantities of OC, Fe, and Al in the B horizons of modal soils increased with soil age. Silt content of surface horizons also increased with age, possibly due to eolian input or physical weathering.

Abstract:

Pine-green moss forests on Podzols exhibit high susceptibility to fire. Subsequent to wildfire, soot and charcoal enter the soil profile and accumulate in the upper part of the podzolic horizon (E). This process results in the development of a greying pyrogenic podzol horizon (Epyr). The maximum concentration of pyrogenic components accumulates in the surface layer of Epyr, which is 1 to 4 cm thick and the darkest in colour. The comprehensive soil descriptions showed the existence of a fine pyrogenic layer between the forest floor and mineral horizon. This layer was not analysed. The current s

Abstract:

Boreal agriculture struggles with soils of lower agronomic value, most of which are sandy with a low water holding capacity (WHC) and prone to nutrient leaching. Biochar amendments are associated with positive effects on soil hydraulic properties and enhanced nutrient retention. However, these effects are strongly related to feedstock type and pyrolysis parameters and depend on biochar application rates and soil types. While biochar could increase the productivity of boreal agriculture by improving water and nutrient use efficiency, little is known about its effects on hydraulic processes in p

An ancient sand-dune system located in the Myall Lakes National Park, N.S.W. (32�28'S., 152�30' E.) supports an open eucalypt forest with Eucalyptus pilularis as one of the co-dominant tree species. Profile development of the sand mass is typical of a light humic podzol. The relative pool sizes of available nutrients contained by the acidic podzol were such that phosphorus was the most limiting for the growth of E. pilularis seedlings. The bulk of seedling phosphorus was assimilated from the A, horizon of this podzol. Soil from the A, horizon was characterized by a low total level of phosphoru

The mobility and fate of these elements and Cr were determined by extractions with sodium pyrophosphate, ammonium oxalate (pH 3.0), dithionitelcitrate and dilute HCl. In some cases, pyrophosphate extractions gave higher values than expected when considering the ammonium oxalate values, confirming that peptizatio

At 21 of the 27 sites, however, the pedons were classified in one family: Orthic Ferro-Humic Podzol, coarse loamy, cold, humid.
