TL;DR: In this paper, the complex developmental history of a paleoargillic brown earth in Plateau Drift has been investigated using mainly micromorphological techniques and eight kinds of pedological features are identified, quantified and related to a probable sequence of soil-forming events.

TL;DR: In this article, a review of the literature showed that deep tillage and modification of soils having unfavorable profiles may increase crop production by providing larger, more favorable zones of soil for the growth, proliferation, and activity of roots.

TL;DR: In this article, the transformation of phyllosilicates by oxalic acid and other complexing agents synthesized by microorganisms that survived partial sterilization was studied and a satisfactory model of weathering in that soil-forming process was provided.

TL;DR: In this article, the total trace element contents of a Scottish soil corresponds to that expected on the basis of the geochemistry of its parent materials and that the influence of agricultural operations on soil contents is of secondary importance.

TL;DR: In this paper, the authors deal with colluvial deposits found in dry valley heads in a farmland area near the village of Berle in northern Luxembourg, where the colluvium shows signs of groundmass illuviation in the form of matriargillans, matrans or agricutans, as this feature is variously called.

TL;DR: In this article, the authors used soil morphology to define sample size and soil maps to locate test sites within defined mapping units, and showed that permanent high ground-water levels were primarily due to low hydraulic gradients and not to a low Ksat.

TL;DR: In this paper, the Fe/Al ratio from pH 9.5 buffered tetraborate extract is proposed as a test to classify the "sols bruns ocreux" and "sol cryptopodzoliques" which are hard to classify in situ according to morphological characteristics.

TL;DR: In this paper, a fixed effects ANOVA model is used to distinguish, within any set having the same variance, those units having different means and variances for measured properties, and the results of the ANOVA and MANOVA analyses give three distinct sets of contrasted groups when the spatial distribution of the mapping units is taken into account.

TL;DR: In this paper, the adsorption coefficients of boric acid in a sandy loam and an organic loamy clay measured by batch equilibration were about twice as high as by elution from cylinders of soil aggregates.

TL;DR: Frost-heave measurements conducted over two winters in frost-susceptible soil at two adjacent Canadian locations, one near Guelph, and the other near Elora, Ontario, are examined in the light of supporting environmental data.

TL;DR: The clay soils on limestone in South Limburg range in age from Holocene (young) to probably Late Tertiary (profile 1) and show correspondingly great differences in their characteristics.

TL;DR: In this paper, pH 4.8 and pH 8.2 are reported for peroxidized clay separates from a group of Irish soils derived from a variety of parent materials.

TL;DR: The Ando soil group was identified during reconnaissance soil surveys in Japan by American soil scientists as discussed by the authors and was later recognized in places as far apart as Alaska, France and New Guinea.

TL;DR: Water contents were measured in a soil profile during the winter from the time of harvest until soil temperatures were greater than 0°C through this profile in the spring by using the Darcy flow law and changes in water flux as discussed by the authors.

TL;DR: The Post-Diamond Hill Paleosol generally underlies Late Pleistocene sediments of the Willamette Formation as discussed by the authors, and the soils are mostly typic Pelloxererts in the fine, montmorillonitic, mesic family.

TL;DR: In this article, the identification of paleosols according to their stratigraphic position facilitates the description of those characteristics affecting land use studies in southern Australia, which have been the subject of earlier studies of soils with regard to land use.

TL;DR: The alteration of the limestone into parent material is described and discussed in this article, where chemical and mineralogical analyses of the solid materials and the chemical analyses of interstitial waters permit the following conclusions about the parent materials: decalcification and desilication have occurred; low-ordered tridymite has been formed by replacement of the carbonates which, together with plagioclases and magnesite (Mg-calcite), have subsequently been transformed into smectite and kaolinite.

TL;DR: In this article, the concentration of inositol hexa-, penta-, and di-and triphosphates were significantly correlated with organic phosphorus, total phosphorus, organic carbon, total nitrogen, inositolin phosphate, and exchangeable iron and aluminium.

TL;DR: In this paper, a detailed laboratory study of rock samples showed that siliceous materials outcropping at these locations are bedrock essentially unaltered since Palaeozoic burial and deformation.

TL;DR: Paleosols in Japan consist of buried soils and relict soils as discussed by the authors, and the former occur primarily in tephra deposit, whereas the latter occupy old land surfaces in various parts of the country.

TL;DR: Paleosolic features are important to land use and management of soils on fan terraces in southwestern Oregon Soil-geomorphology studies identified relict duripans and established the distribution of associated Durochrepts, Duraquolls and Argixerolls These soils represent two late Pleistocene geomorphic surfaces, each with distinct kinds of periglacial patterned ground Soil behavior is discussed in terms of soil characteristics and qualities as discussed by the authors.

TL;DR: In this article, three representative soil profiles were selected and studied in detail, and some observations and conclusions on the distribution, age and characteristics of these soils are presented, and weathering and soil formation are discussed in the second and third parts.

TL;DR: The Graulehme (grey loams) are relict soils or paleosols formed during the Tertiary or earlier but persisting locally on land surfaces as discussed by the authors.

TL;DR: Paleosols at the land surface and others that are buried are formed almost entirely from tephra parent materials as discussed by the authors, and current information on nutrient uptake by trees, on highway construction, pipe corrosion, and construction of earthworks is summarized briefly in this paper.

TL;DR: In this paper, the potentials at the interphase boundary of different minerals in contact with an electrolyte acquired by the association of the different minerals may accelerate or retard weathering of the mineral surfaces and is shown to cause surface precipitates and changes in the composition of the intervening electrolyte.

TL;DR: In this article, soil samples were fractionated by sedimentation in water and by flotation in heavy liquids to separate complexed and uncomplexed organic and inorganic components, and organic matter was concentrated in low density fractions in all separates.
