Significant effects of soil fauna on soil structure are achieved mainly by a few groups among the larger soil invertebrates that are widely distributed and generally present in large numbers. Of these groups the most important are earthworms, termites and ants.

SOIL-STRUCTURE AND SOIL-STRUCTURE-SOIL INTERACTION: EXPERIMENTAL EVIDENCE AT THE VOLVI TEST SITE
Journal of Earthquake Engineering, 2005This paper shows the results of two passive experiments carried out at the European Volvi test site where a scaled building has been constructed. The first experiment was performed to study the motion of the structure excited by two small earthquakes. For one month, six strong-motion recorders were installed within the structure, at the top and at the ...

Exploring the relationship between soil structure and soil functions via pore-scale imaging
Geoderma, 2020Biogeochemical and structural heterogeneities at the pore-scale govern processes in soil in many ways. They are therefore of key importance for understanding soil functioning. Prominent examples are the stabilization of soil organic matter due to reduced

Soil Dynamics and Earthquake Engineering, 2020
Soil-structure interaction (SSI) phenomena subjected to seismic loadings are investigated in this study. Firstly, shaking table tests on dynamic soil‐structure interaction subjected to seismic loadings are carried out, and SSI effects are analyzed ...

Three-dimensional constitutive model for cyclic behavior of soil-structure interfaces
Soil Dynamics and Earthquake Engineering, 2020Many soil-structure interaction systems experience a three-dimensional loading condition (i.e. shear coupling) at their interfaces. In this study, an elasto-plastic constitutive formulation for interfaces in soil-structure interaction problems is ...

Soil drying and soil structure
2020<p>Classical soil water retention curves relate tension and water content in soil. Often, the tension is equated with the equivalent diameter of the largest water-filled pores, using the capillary rise equation. This relationship is known to be an approximate one as most soils contain clay minerals that swell and shrink with ...

Soil structure formation along an agricultural chronosequence
Geoderma, 2019During soil formation, the interaction of different biota (plants, soil fauna, microbes) with weathered mineral material shapes unique structures depending on the parental material and the site specific climatic conditions.

Soil Structure and Soil Biology
Ecology, 1936As Lars-Gunnar Romell has emphasized ('30, p. 842), "Burger ('22) with good reason, compares agricultural soil to an unorganized mass of building material, whereas the natural forest soil, with its definite, stable organization, is like a house built from this material." " It is more and more generally recognized that a natural soil, like a living ...

Sandy soils have poor soil structure, low water retention and low crop productivity. A bentonite-humic acid (B-HA) mixture was applied at a single rate of 30 Mg ha−1 to a sandy degraded soil of China for improving soil physical properties and hydric ...
