Content and composition of inorganic X-ray amorphous materials in temperate climate soils determined by the Rietveld method

Sileola Joseph Akinbodunse, Laura S. Schnee, Andre Baldermann, Kristian Ufer et autres

Inorganic X-ray amorphous materials (iXAMs) are reactive soil components, including nanocrystalline minerals and mineraloids, often overlooked by mineralogical analyses. We evaluated their abundance and composition in temperate climate soils (Cambisol, Podzol, Chernozem, and Stagnosol) using Rietveld analysis of powder X-ray diffraction data …

Soil development, mineralogy and organic matter stocks in a West Greenlandic tundra landscape

Tino Peplau, Patrick Liebmann, Claudia Fiencke, Selina Undeutsch et autres

• We examined soils from different landscape positions in a glacially shaped valley. • Slope dynamics and water availability control soil development and carbon stocks. • Soil carbon stocks are spatially highly heterogenous and underestimated in models. • Solifluction and cryoturbation are …

Antimony(V) reaction with particulate natural organic matter: Sorption behavior, binding mechanism, and environmental implications

Christian Mikutta, Iso Christl, Kerstin Hockmann, Max Niegisch et autres

Antimony (Sb) is a metalloid extensively used in industrial products with a high potential for accumulation in organic-rich soils. Under oxic conditions, dissolved Sb occurs in its pentavalent oxidation state, Sb(V), but little is known about sorptive interactions between Sb(V) and natural …

Soil organic matter quality in an olive orchard differently managed for 21 years: Insights into its distribution through soil aggregates and depth

Rosangela Addesso, Fabrizio Araniti, Andrea Bloise, Alba N. Mininni et autres

Among the current global challenges, the research of new practices aimed at mitigating soil impoverishment, exacerbated by the pressing climate changes, is the most urgent. Studying soil organic matter (SOM) ecological dynamics and comparing the conventional intensive farming practices with the emerging …

Redox cycling of straw-amended soil simultaneously increases iron oxide crystallinity and the content of highly disordered organo-iron(III) solids

Christian Mikutta, Max Niegisch, Aaron Thompson, Ricarda Behrens et autres

Iron speciation in soils is influenced largely by its redox state, but the extent of and controls on Fe speciation during recurrent reduction and oxidation events are not fully understood. To investigate the effects of organic matter (OM) inputs and the frequency …

Clay Types Modulate the Toxicity of Low Concentrated Copper Oxide Nanoparticles Toward Springtails in Artificial Test Soils

Jonas Fischer, Ghanem D. A. Talal, Laura S. Schnee, Patricks Voua Otomo et autres

Abstract Copper oxide nanoparticles (CuO-NPs) can be applied as an efficient alternative to conventional Cu in agriculture. Negative effects of CuO-NPs on soil organisms were found, but only in clay-rich loamy soils. It is hypothesized that clay–NP interactions are the origin of …

Thermogravimetric-calorimetric characterisation of organic matter in oxide-rich tropical soils

Laura S. Schnee, Stephan Kaufhold, Albert Ngakou, Juliane Filser

Tropical soils are increasingly subjected to both site conversion and intensification of agricultural practices, leading to cultivation-induced losses of soil organic matter (SOM) and associated nutrients. Hence, robust techniques for the qualitative characterisation of SOM in heavily weathered tropical soils are required. …

Does biochar contribute to soil organic matter accumulation? – A tropical perspective

Laura S. Schnee, Albert Ngakou, Juliane Filser

Tropical soils are often deeply weathered and vulnerable to degradation. Biochar appears a promising means to improve soil quality while sequestering carbon into the soil. Yet, sustainable soil amelioration depends on stable soil organic matter (SOM) stocks for nutrient retention, water uptake …

Does biochar enhance soil organic matter formation in tropical soils?

Laura S. Schnee, Albert Ngakou, Juliane Filser

Abstract Tropical soils are often deeply weathered and vulnerable to degradation. Biochar is a promising means to improve physico-chemical characteristics such as pH or bulk density. Sustainable soil amelioration is best achieved by improving biological activity, resulting in enhanced soil organic matter …

Long-term impact of single biochar and compost application on soil aggregation

Laura S. Schnee, Hartmut Koehler, Albert Ngakou, Thilo Eickhorst

Abstract Soil aggregation is an important indicator of soil quality and highly responsive to management such as application of organic amendments. Compost generally increases aggregate stability and enhances soil microbial activity, while the effects of biochar on these factors remain inconclusive. We …
