TLDR
In this paper, the authors used X-ray microtomography (micro-CT) to evaluate the 3D pore size distribution and morphology of both undisturbed soil cores (5 cm diameter, 6 cm length) and aggregates (sieved at 5-6mm).About:

Journal ArticleDOI
Soil macro- and microstructure as affected by different tillage systems and their effects on maize root growth
TL;DR: In this article, the authors compared conventional (CT) and no tillage (NT) practices to evaluate their effects on soil structure and maize root morphology and dynamics during a two-year transition period.
Journal ArticleDOI
Relations between macropore network characteristics and the degree of preferential solute transport
TL;DR: In this paper, the authors examined the relationship between macropore network characteristics, hydraulic properties and state variables and measures of preferential transport and found that columns with smaller macroporosities, poorer local connectivity, and smaller near-saturated hydraulic conductivities exhibited a greater degree of preferential transfer.

Steffen Schlüter,Caroline Großmann,Caroline Großmann,Julius Diel,Gi-Mick Wu,Sabine Tischer,Annette Deubel,Jan Rücknagel +7 more
TL;DR: In this article, a long-term field experiment on tillage practices at the Westerfeld trial in Bernburg, Germany (25 years of different management) is investigated in a X-ray microtomography with bulk properties like bulk density, air capacity and saturated hydraulic conductivity, as well as integrative, ecological properties like earthworm abundance and crop yield.

Effect of vegetation type on microstructure of soil aggregates on the Loess Plateau, China
Dong Zhao,Mingxiang Xu,Mingxiang Xu,Guobin Liu,Luyang Ma,Shengmin Zhang,Tiqiao Xiao,Guanyun Peng +7 more
TL;DR: In this article, the authors used synchrotron-based high-resolution X-ray micro-computed tomography to quantify the microstructure of soil aggregates under four types of revegetation and an active cropland on the Loess Plateau.

Impact of Long-Term Fertilization Practice on Soil Structure Evolution
Muhammad Naveed,Per Moldrup,Hans-Jörg Vogel,Mathieu Lamandé,Dorthe Wildenschild,Markus Tuller,Lis Wollesen de Jonge +6 more
TL;DR: In this paper, the authors characterized soil structure development and evolution in six plots that were amended with varying amounts of animal manure (AM) and NPK fertilizer over a period of 106 years in a long-term fertilization experiment in Bad Lauchstadt, Germany.

Organic matter and water-stable aggregates in soils
Judith. Tisdall,J.M. Oades +1 more
TL;DR: In this article, the effectiveness of various binding agents at different stages in the structural organization of aggregates is described and forms the basis of a model which illustrates the architecture of an aggregate.

A history of research on the link between (micro)aggregates, soil biota, and soil organic matter dynamics
TL;DR: In this article, Tisdall and Oades [J. Soil Sci. 62 (1982) 141] coined the aggregate hierarchy concept describing a spatial scale dependence of mechanisms involved in micro- and macroaggregate formation.
