Journal ArticleDOI
Characterization of slow pyrolysis biochars: effects of feedstocks and pyrolysis temperature on biochar properties.
Stefanie Kloss,Franz Zehetner,Alex Dellantonio,Raad Hamid,Franz Ottner,Volker Liedtke,Manfred Schwanninger,Martin H. Gerzabek,Gerhard Soja +8 more
TL;DR: It is demonstrated that biochars are highly heterogeneous materials that, depending on feedstock and HTT, may be suitable for soil application by contributing to the nutrient status and adding recalcitrant C to the soil but also potentially pose ecotoxicological challenges.
Journal ArticleDOI
Mineralogical and geochemical indicators of the polygenetic nature of terra rossa in Istria, Croatia
TL;DR: In this paper, the difference in particle size, mineralogy and geochemistry observed between terra rossa and the insoluble residue of limestones and dolomites was analyzed.
Journal ArticleDOI

Enhanced Cu and Cd sorption after soil aging of woodchip-derived biochar: What were the driving factors?
Maria V. Rechberger,Stefanie Kloss,Shan-Li Wang,Johannes Lehmann,Harald Rennhofer,Franz Ottner,Karin Wriessnig,Gabrielle Daudin,Helga C. Lichtenegger,Gerhard Soja,Franz Zehetner +10 more
TL;DR: The data suggest that the accessibility of BC's pore network and reactive surfaces is likely to be the overriding factor responsible for aging-related changes in HM sorption capacity, rather than direct interactions of HMs with oxidized functional groups.
Journal ArticleDOI
Results of an inter-laboratory comparison of methods for quantitative clay analysis
TL;DR: In a comparison of analytical methods in clay mineralogy, two clay samples (from Hennersdorf and Freydegg) of different clay composition were analyzed by 19 laboratories mainly by XRD as mentioned in this paper.
