    Beeldanalyse brengt kwaliteit substraten snel en objectief in kaart (interview met Chris Blok)
    Staalduinen, Jan van; Blok, C. - \ 2007
    Onder Glas 4 (2007)10. - p. 66 - 67.

    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.

    Micromorphology was used to reconstruct the paleo-landscape in which a woodland had grown between about 200 BC and 600 AD in Zwolle-Stadshagen. This is the second article of a set of five on the integrated reconstruction of this woodland of the past.

    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.

    Aggregation, organic matter, and iron oxide morphology in oxisols from Minas Gerais, Brazil

    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.
