TLDR
The aggregation of clays after the addition of organic materials is described in this article, where clays were incubated with or without added organic matter in the form of grass, straw, or charcoal and needed to be dried to a water potential of −1.5 MPa or less to aggregate.Abstract:
The aggregation of clays after the addition of organic materials is described. Clays were incubated with or without added organic matter in the form of grass, straw, or charcoal and needed to be dried to a water potential of −1.5 MPa or less to aggregate. It was the fine fraction of the clay (<0.5 μread more

Soil organic matter turnover is governed by accessibility not recalcitrance
TL;DR: In this article, the authors explore how advances in quantitative analytical techniques have redefined the new understanding of SOM dynamics and how this is affecting the development and application of new modelling approaches to soil C.

TL;DR: In this paper, a harmonized concept for aggregates in soils is proposed that explicitly considers the structure and build-up of microaggregates and the role of organo-mineral associations.

Implications for Soil Properties of Removing Cereal Straw: Results from Long-Term Studies
TL;DR: In this article, the RothC model was used to simulate the effect of straw removal on soil organic carbon (SOC) and related properties, and the authors concluded that it would be unwise to remove straw every year as this is likely to lead to deterioration in soil physical properties.

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.

Advances in characterization of soil structure
TL;DR: Soil structure is defined as "the spatial heterogeneity of the different components or properties of soil" as discussed by the authors, and it is a property of soil that is important for plant development, soil water balance and soil workability.

Macro-aggregation of soils by biological bonding and binding mechanisms and the factors affecting these: a review
TL;DR: In this article, the authors present an analysis of the labile bonding (organic compounds) and binding (hyphae and roots) mechanisms involved in stabilising soil into macro-aggregates in soils.

Aggregation of soil by fungal hyphae
TL;DR: In this article, the authors examined the aggregation of soil clay by saprophytic (Rhizoctonia solani and Hyalodendron sp.) and mycorrhizal (Hymenoscyphus ericae and Hebeloma sp.) fungi.

The role of roots, fungi and bacteria on clay particle organization. An experimental approach
TL;DR: Modifications of the microstructure were recognized with all species, the size depending on the size of organism, and polysaccharide-mediated aggregation was predominant.
