Combination of Imaging Infrared Spectroscopy and X-ray Computed Microtomography for the Investigation of Bio- and Physicochemical Processes in Structured Soils [PDF]

Frontiers in Environmental Science, 2020
Soil is a heterogeneous mixture of various organic and inorganic parent materials. Major soil functions are driven by their quality, quantity and spatial arrangement, resulting in soil structure.

Mycorrhizas and soil structure [PDF]

New Phytologist, 2006
SummaryIn addition to their well‐recognized roles in plant nutrition and communities, mycorrhizas can influence the key ecosystem process of soil aggregation. Here we review the contribution of mycorrhizas, mostly focused on arbuscular mycorrhizal fungi (AMF), to soil structure at various hierarchical levels: plant community; individual root; and the ...

Identification of Group II Intron RmInt1 Binding Sites in a Bacterial Genome

Frontiers in Molecular Biosciences, 2022
RmInt1 is a group II intron encoding a reverse transcriptase protein (IEP) lacking the C-terminal endonuclease domain. RmInt1 is an efficient mobile retroelement that predominantly reverse splices into the transient single-stranded DNA at the template ...

SOIL SURFACE CRUST: ITS SIGNIFICANCE, TYPES AND MECHANICS OF FORMATION. A REVIEW [PDF]

Mesopotamia Journal of Agriculture, 2020
Most of the agricultural soils around the world suffer from increased soil degradation and erosion and reduce moisture conservation, which is the decisive factor in agricultural crop production, and among these problems is the phenomenon of Surface Soil ...

Soil–Water–Structure Interactions

Geotechnics, 2023
Interactions between soil, fluids (e.g., water), and structures are intrinsic to most geotechnical problems. However, these can be extremely complex and further understanding is needed in this field. Soil–water–structure interactions can be studied on many different scales (micro to macro) and perspectives (experimental, numerical, and theoretical). In

Effect of soil permeability on soil–structure and structure–soil–structure interaction of low-rise structures

Géotechnique, 2022
Earthquake-induced soil liquefaction can generate excessive damage to building structures due to significant reduction in soil effective stress. With increasing urbanisation and population growth, the performance of closely spaced buildings, such as those in towns and cities, is of greater concern where structure–soil–structure interaction (SSSI) may ...

Habitat structure: a fundamental concept and framework for urban soil ecology [PDF]

, 2007
Habitat structure is defined as the composition and arrangement of physical matter at a location. Although habitat structure is the physical template underlying ecological patterns and processes, the concept is relatively unappreciated and underdeveloped

Light structures phototroph, bacterial and fungal communities at the soil surface [PDF]

, 2013
The upper few millimeters of soil harbour photosynthetic microbial communities that are structurally distinct from those of underlying bulk soil due to the presence of light. Previous studies in arid zones have demonstrated functional importance of these

Macro- and microscale gaseous diffusion in a Stagnic Luvisol as affected by compaction and reduced tillage [PDF]

, 2008
Intensification of mechanical agriculture has increased the risk for soil compaction and deformation. Simultaneously, reduced tillage practices have become popular due to energy saving and environmental concerns, as they may strengthen and improve the ...
