Effect of phosphogypsum and poultry manure on aggregate-associated alkaline characteristics in bauxite residue.
TL;DR: Findings reveal that application of phosphogypsum and poultry manure directly alter the distribution of exchangeable bases and alkaline indicators within residue aggregates, resulting in aggregate size distribution and microstructure variations.
Journal ArticleDOI
Going submicron in the precise analysis of soil structure: A FIB-SEM imaging study at nanoscale
TL;DR: In this article, focused ion beam plus scanning electron microscopy (FIB-SEM) imaging technique was used for the characterization of pore size distributions and observed pore inscribed radii ranging from 2.5 µm to 1 µm.
Journal ArticleDOI
Estimating soil porosity and pore size distribution changes due to wetting-drying cycles by morphometric image analysis
TL;DR: In this paper, the effect of W-D cycles in the soil porous system of core samples submitted to contrasting management practices (conventional tillage- CT, minimum tillage - MT, no-tillage - NT) was analyzed.

Temporal variations of the hydraulic conductivity characteristic under conventional and conservation tillage
Janis Kreiselmeier,Janis Kreiselmeier,Parvathy Chandrasekhar,Parvathy Chandrasekhar,Thomas Weninger,Andreas Schwen,Stefan Julich,Karl-Heinz Feger,Kai Schwärzel +8 more
TL;DR: In this article, the effects of a conventional tillage, reduced tillage and no tillage (NT) system on hydraulic conductivity characteristic (HCC) were investigated on an experimental field with a Haplic Luvisol in Eastern Germany throughout part of a winter wheat growing season.
Journal ArticleDOI
Long-term effects of sustainable management practices on soil properties and crop yields in rainfed Mediterranean almond agroecosystems
TL;DR: The long-term effects of conservation agriculture on soil physical and chemical properties and their relationship with crop yields are still relatively poorly understood as mentioned in this paper, and the effects of those practices vary widely depending on climatic and edaphic conditions and cannot be generalized for all agro-ecological regions and crop types.

A closed-form equation for predicting the hydraulic conductivity of unsaturated soils
van Genuchten,M. Th. +1 more
TL;DR: Van Genuchten et al. as mentioned in this paper proposed a closed-form analytical expression for predicting the hydraulic conductivity of unsaturated soils based on the Mualem theory, which can be used to predict the unsaturated hydraulic flow and mass transport in unsaturated zone.

The Lognormal Distribution.
J. Aitchison,J. A. C. Brown +1 more
TL;DR: Lloyds Bank has its main root in a substantial private bank founded in Birmingham nearly two centuries ago; one hundred years ago this Bank still had only the one office in Birmingham, with a related private banking house in Lombard Street, and by amalgamation it has absorbed scores of other eighteenth and nineteenth century banks, both private and joint stock, and at least two of the former reach back into Restoration London, perhaps Cromwellian London.

The lognormal distribution
TL;DR: Lloyds Bank has its main root in a substantial private bank founded in Birmingham nearly two centuries ago; one hundred years ago this Bank still had only the one office in Birmingham, with a related private banking house in Lombard Street, and by amalgamation it has absorbed scores of other eighteenth and nineteenth century banks, both private and joint stock, and at least two of the former reach back into Restoration London, perhaps Cromwellian London.

Lognormal Distribution Model for Unsaturated Soil Hydraulic Properties
TL;DR: In this paper, the water retention model developed by Kosugi was modified to be compatible with Mualem's model in order to derive an analytical expression for the relative hydraulic conductivity Kr.

Tillage effects on soil hydraulic properties in space and time: State of the science
TL;DR: In this article, a literature review addresses the quantitative effects of soil tillage and associated management (e.g., crop residues) on the temporal and spatial variability of soil hydraulic properties, including incidental management effects such as soil compaction, and natural sources of variability, such as topography.
