    Het onderzoek naar de kwaliteitsaspecten van substraten wordt steeds verfijnder. Wageningen UR tilt het visuele onderzoek naar een hoger plan met behulp van beeldanalyse, waarvoor fer Weerheijm van Independent Substrate Consulting apparatuur beschikbaar stelde. Volgens onderzoeker Chris Blok zal het tijdrovende voortraject potgrond en substraatleveranciers op termijn veel werk besparen en betere resultaten opleveren
    Strooiselafbraak onder verschillende loofboomsoorten op de stuwwal bij Doorwerth : micromorfologisch onderzoek van de humusprofielen

    Dit rapport presenteert de resultaten van een micromorfologisch onderzoek van slijpplaten gemaakt in humusprofielen onder verschillende loofboomsoorten op een zwak lemige stuwwalbodem bij Doorwerth (Gelderland). Er werden opstanden vergeleken van linde, esdoorn, haagbeuk, eik en beuk. Het onderzoek was het vervolg van eerder gepubliceerd onderzoek naar de relatie tussen loofboomsoort, humus en ondergroei op dezelfde locaties (Alterra-rapport 920). Hieruit bleek dat onder invloed van het `rijke¿, goed verterende bladstrooisel van linde, esdoorn en haagbeuk een ontwikkeling in de richting van een `rijker¿ bostype op gang te zijn gekomen. Alleen onder linde was echter binnen 40 jaar een goed ontwikkelde, soortenrijke Carpinion-vegetatie met meerdere oud-bossoorten ontstaan. Het micro¬morfologisch onderzoek ondersteunt deze resultaten, geeft inzicht in de onderliggende processen en laat zien welke groepen bodemorganismen bij de vorming van de verschillende humusvormen betrokken zijn. Ook wordt duidelijk dat bodemverdichting ten gevolge van berijding de ontwikkeling naar een `rijker¿ bostype kan vertragen.

    Tunnels in feldspar grains, assumed to be created by fungal hyphae, were first discovered in a boreal podzol. In this paper, we further describe the phenomenon of mineral tunneling by determining the rate of feldspar tunneling across a north Sweden podzol chronosequence. The chronosequence is a result of ongoing land uplift, which started after the retreat of glaciers about 9000 years ago. The sequence comprises a series of soils that began developing on glacial tills 190-7800 years ago. Feldspar tunneling was concentrated in the uppermost 2 cm of the E horizon, and its frequency increased significantly with soil age. Although no tunnels were found in feldspar grains from the youngest soil (190 years), they were seen more frequently in soils aged 2000 years and older. This lag phase in tunnel formation of about 2000 years coincided with the disappearance of the easily weatherable potassium-(K) and calcium (Ca)-containing minerals biotite and hornblende and with the appearance of etch pits on feldspar grains. In the oldest soil (7800 y), about 25␘f the feldspar grains in the upper 2 cm of the E horizon were tunneled. Within site variation in tunnel frequency was high, and we were able to exclude spatial variations in mineralogy and texture as a possible explanation. The shape of the tunnels, their depth distribution, and the fungal hyphae found inside them all offer support for the previous assumption that their formation is mediated by biological activity involving fungi. The results of this investigation also indicate that the bioavailability of Ca and K may be a factor in tunnel formation.

    The characteristic strong aggregation observed in Oxisols is usually attributed to the presence of free aluminium or iron compounds. Previous investigation of Oxisols from Minas Gerais, Brazil, suggested that iron oxide minerals do not necessarily play a role in aggregation. Oxisol profiles developed on different parent materials (rock-saprolites and sediments), and with different degrees of polygenesis, were investigated to assess whether the physical makeup, rather than the iron content, determines aggregation. Oxisols were investigated by means of micromorphology and laser diffraction grain-sizing. Grain-size distribution curves were determined after three pre-treatments: shaking with water; removal of organic matter; and removal of organic matter followed by deferration. Micromorphology indicated that soils developed on rock-saprolites have hematite droplets (discrete, red colored, equidimensional concentrations) in the saprolite, whereas droplets are not found in soils on Tertiary sediments. However, secondary iron accumulations related to periodic water saturation are encountered in the soils on sediments and not in the soils on rock-saprolites. Grain-size distribution curves showed that the Oxisols on rock-saprolites do not have strong aggregation because of iron oxides alone. Conversely, aggregation by iron oxides is evident in the Oxisols on sediments. This indicates that remobilization of iron during soil formation is essential for iron forms to play a role in aggregation. These findings suggest that the mode of formation and iron mineralogy affect aggregation.

    Clay mineralogical studies by X-ray diffraction performed on extracted <2-μm fractions do not always represent all clay mineral constituents present in the soil. In this work, transmission X-ray diffraction (TXRD) was applied to undisturbed microsamples of optically homogeneous mineral soil fabrics and features. These microsamples were isolated by microdrilling their periphery in soil thin sections, then removing them, and transferring them to glass capillaries for TXRD analysis. The usefulness of this technique for supplying in situ mineralogical information on identification, structure, and natural orientation of soil constituents was tested on mineral microfabrics and features of primary and secondary phyllosilicates. The study demonstrated that TXRD allowed detailed, representative interpretations of undisturbed mineral features and fabrics. In particular, this technique allowed us (1) to compare mineralogical compositions at selected microlocalities, (2) to study natural preferred orientations, and (3) to detect small amounts of minor mineral interstratification phases. In addition, complementary information on crystallography and crystal chemistry may be obtained by performing analytical transmission electron microscopy on the same microsample. | Clay mineralogical studies by X-ray diffraction performed on extracted <2-μm fractions do not always represent all clay mineral constituents present in the soil.

    The influence of time as a soil forming factor was studied on an evolutionary sequence of five soils (1850 radiocarbo years BP-ca. 120,000 BP) developed in rhyolitic tephra deposits in New Zealand. New micromorphological observations were combined with existing macromorphological, chemical, textural, and clay mineralogical analyses to assess the extent of polygenesis in the soils. The younger soils (1850 BP to ca. 22,600 BP) are characterised by initial weathering and little secondary mineral formation. This status is expressed by abundant pumice fragments and fresh, easily weatherable minerals, as well as a low clay content with an isotropic character. Comminution and neoformation are the main pedological processes. The older soils (ca. 120,000 BP) are characterised by a high degree of alteration of primary minerals, little or no pumice fragments, clay illuviation, gleying, and a high clay content (>80%) consisting of a range of crystalline clay minerals including halloysite, gibbsite, kaolinite, and vermiculite, plus crystalline iron oxides. Evidence of polygenesis can be observed in the micromorphology of the older soils: (1) the range of secondary minerals is the result of the integration and succession of soil-forming processes through time; (2) the accumulatory character of the tephra deposits has resulted in stronger weathering of the lower horizons than upper horizons because of continuous pedogenesis. Such polygenesis in the older soils supports the view that the older the soil, the more polygenetic it is likely to be. Copyright

    Mineral transformation at the earth surface is a complex process. In volcanic ejecta, such transformations tend to be fairly rapid. Many weathering studies on volcanic materials have been carried out at different scales of observations, mostly using bulk samples. However, to get a proper understanding of the mechanisms of weathering of primary minerals and formation secondary minerals it is necessary to obtain data of undisturbed material at the scale of observation that micromorphology and submicroscopy deal with. Weathering studies at the micrometre scale with help of micromorphology showed the heterogenous character of mineral weathering and the co- existence of different secondary minerals.

    The main objective of papers in this thesis was to characterize and explain alteration of primary minerals and formation of secondary minerals at the particle level in volcanic soils in relation to (micro) environmental conditions.
    Thin sections of volcanic soils were studied by micromorphology, and relevant features were characterized chemically and mineralogically by submicroscopical methods performed on (un)disturbed samples isolated from thin sections.
    Mineral transformations were studied both on sites in the temperate humid zone and in the humid tropics.

    In a chronosequence of Quaternary terraces of the Allier in France, micromorphological and sub microscopical analyses showed:
    - Alteration of basaltic particles leads to clay formation whereas weathering of granite fragments contributes to the sand fractions.
    - A relative increase in the contents of Ti, Al, and Fe and a decrease of K, Na, Ca, and Si occur in weathering rinds of basalt pebbles. Differences in weathering intensity are predominantly a function of chemical composition of the basalt rather than a function of time.
    - A mass balance calculation carried out on an isovolumetric, altered basalt pebble with a fresh core, and on an enclosed, genetically related neoformed clay coating showed that all elements, except Fe were leached from all weathering rinds. Only Si, Al and some Ca were found in the clay coating, and part of the Al was derived from an external source.
    - Isotropic and anisotropic coatings occur in a Paleosol in an older terrace. Micromorphological observations demonstrated that such coatings are genetically related. The isotropic coating consists of allophanic material with minor amounts of 2:1 phyllosilicates, whereas the anisotropic types consist of 2:1 phyllosilicates only. Both types result from recombination of trachytic weathering products under restricted leaching conditions during coating formation.
    - Micromorphological observation demonstrated three types of coatings in two Planosols in two older terraces. Isotropic and anisotropic, translucent materials occur locally within one coating, suggesting a genetic similarity. These coatings are due to secondary mineral formation, The third type, anisotropic dusty clay coatings clearly resulted from clay illuviation. Cluster analyses reveal that the coatings of the same type were chemically more alike than different coatings in the same profile. About 83% of the grouped samples were classified correctly as either isotropic and anisotropic weathering coatings or anisotropic illuviation coatings.

    A technique is described to isolate undisturbed microparts of pedofeatures from thin sections. Such microparts can subsequently be analysed by Transmission Electron Microscopy. This technique allows performance of micromorphological, mineralogical and chemical analyses on one undisturbed micro sample at micrometre to nanometre scales.

    Isotropic coatings in the C horizon of a young Hapludand in Guadeloupe and in the C and R horizons of an old Hapludand in Costa Rica, both developed on andesitic volcanic materials were allophanic. Isotropic coatings present in the Bw horizons of both soils contain allophane and imogolite. The Al/Si molar ratios in the coatings in the Bw horizons are higher than those in the coatings of the C and R horizons. Anisotropic coatings are wholly gibbsitic and occur only in the Bw horizon of the older Costa Rican Hapludand. The gibbsitic coatings show a gradual transition to isotropic coatings and both types looks alike in plane polarized light suggesting a genetic relationship. The allophane coatings resulted from initial weathering of the parent materials, whereas the gibbsite coatings represent the ultimate stage of secondary mineral formation. The differences in chemical and mineralogical composition of the coatings are thought to be the result of different leaching conditions at the macro and micro scale.

    2:1 Phyllosilicates in Hapludands on Holocene andesitic beach ridges in Costa Rica occur as clay pseudomorphs after primary minerals. They are inherited from hydrothermally altered parent material from which the beach ridges were derived, and are not due to post depositional soil formation. Weathering and biological activity affect the clay pseudomorphs which leads to clay- sized particles consisting of 2:1 phyllosilicates. They are incorporated in the allophanic groundmass that results from actual soil formation in the Hapludands.

    Isotropic coatings also found in a West Java (Indonesia) Oxisol on andesitic volcanic parent materials are probably due to weathering of airborne ash additions. The coatings recrystallize to anisotropic coatings suggesting a neoformed genesis. Both types of coatings appear to be common in three andesitic catenas in Indonesia. The amount of coatings and the crystallinity tend to increase as the dry season become more pronounced. The anisotropic coatings can easily be confused with illuviation coatings.

    In the past, investigations on surface seals developing under simulated rains usually were performed with uniform rainfall intensities. Recent studies, however, showed that varying-intensity rains affect erosion and volumes of runoff. We conducted a study on surface sealing under varying-intensity rains using physical and morphological methods. Four 1-h-duration rainfall patterns were used: S1, S2, S3 and S4, with mean rainfall intensities of 83, 69, 65, and 51 mm h-1, respectively, and highest intensities of 148, 120, 111, and 100 mm h-1, respectively. Two experiments were performed in triplicate: (i) in packed soil columns, pressure heads at 1-cm depth were measured, and runoff (Rt) and wash sediment (St) collected at short time intervals during S1, S3, and S4 patterns; and (ii) packed shallow soil flumes were successively exposed to 10, 15, 30, 40, and 60 min of S2 and S4 patterns, and the surface was then characterized by micromorphological analysis of thin sections (S2) and top-view photographs (S2 and S4). The largest differences between rainfall patterns occurred during the intensity peaks (10–30 min): at the end of these periods, measured surface seal hydraulic conductances (β) attained values of 0.80, 0.25, and 0.51 h-1 for S1, S3, and S4, respectively. These relative β values are thought to be due to partially open surfaces as a result of microrill erosion (S1), complete sealing without erosion (S3), and incomplete sealing (S4). Presented Rt, St, and morphological data support these conclusions. After 5 min of the intensity peaks of S2, surface seals attained maximum observed thickness and minimum macroporosity (>30 µm). Planar voids (>500 µm) were eliminated at this point. Under continuing rain, erosion reduced the seal thickness and increased macroporosity, mainly as planar voids

    Dutch Late Weichselian braided river deposits and Holocene meandering river deposits of the Rhine have been studied and compared. Cross sections demonstrate the lateral and vertical variations of the Late Weichselian sediments. Soil mapping of these deposits, even on a very detailed scale, proves very difficult. Best results have been obtained with a legend based on hydrology enabling the distinction of topo-hydrosequences of well drained brown soils, imperfectly drained mottled soils and poorly drained grey soils.

    Advanced soil formation and notably the dramatic processes in the Late Weichselian period (decalcification, clay illuviation, pseudogleying, periglacial formation of a highly reoriented, very dense microstructure) have caused clay mineralogical, chemical and physical changes in the Late Weichselian soils.

    The well drained and imperfectly drained Late Weichselian soils have an argillic horizon (Alfisols, Luvisols), occasionally with very low base saturation (Ultisols, Acrisols) and with strong subsequent pseudogleying in the imperfectly drained soils. The Holocene soils demonstrate decalcification and biogenic homogenization as well as some gleying according to their drainage position. These soils are classified as Inceptisols (Cambisols), occasionally as Mollisols (Phaeozems).

    Less favourable physical characteristics and behaviour (soil strength, structure stability and tillage behaviour) of the Late Weichselian soils and soil material is quantitatively documented. Differences with the Holocene soils and soil material are statistically highly significant and are caused by differences in texture, content, quality and distribution of organic matter and the highly reoriented, very dense microstructure.

    Use as permanent grassland or ley in the crop rotation is recommended to increase levels of biological activity. This seems the only remedy for the imperfectly and poorly drained Late Weichselian soils that are compacted by natural soil forming processes not counteracted by biological activity. Very recently improved drainage of large areas of Late Weichselian imperfectly drained soils has increased the saturated hydraulic conductivity to noncritical levels through increased earthworm activity to some metres depth.

    A study was made of those morphological and physical soil properties considered to govern root development.

    A deep and wide-branched root system was shown only to develop in a soil containing a permanent heterogeneous pore system, formed by biological activity in the profile. Therefore a distinction was made between biogenic structures having a relatively heterogeneous pore-size distribution and physicogenic and geogenic structures with a more homogeneous one.

    To demonstrate the effect of differences in management on soil structure in originally similar profiles, three types of land use were compared. Use as arable land proved to give rise to the formation of compacted surface soils with physicogenic structures. Here, mechanical forces leading to degeneration of structure were not compensated by biological regeneration. The same soil under horticulture was, however, shown to have a high biological activity, through added organic manure, and to yield very porous surface soils.

    Land, used as pasture, proved to have intermediate properties in this regard. Only with sufficient drainage this favourable biological effect was found. Methods, developed to study the occurrence of biopores, were applied in some small soil surveys. It was suggested to include the biopore concept in both soil suitability and classification studies.
