Subsoil Compaction: A hidden form of Soil Sealing in Europe [PDF]

open access: yes, 2001
There are two definitions of ‘soil sealing’: (I) ‘covering (sealing) the soil surface by impervious materials, e.g. concrete, metal, glass, tarmac and plastic’; and (II) ‘changing the nature of the soil such that it behaves as an impermeable medium, e ...

An investigation of tillage systems and implement design for water conservation in semi arid conditions in Botswana

open access: yes, 2006
Botswana, as a semi arid country, is faced with serious shortage of moisture for crop production. Its challenging climatic condition makes the little moisture received from summer rainfall insufficient.

Derivation of a macroscopic model for transport of strongly sorbed solutes in the soil using homogenization theory [PDF]

open access: yes, 2010
In this paper we derive a model for the diffusion of strongly sorbed solutes in soil taking into account diffusion within both the soil fluid phase and the soil particles.

Porosity imaging in porous media using synchrotron tomographic techniques [PDF]

open access: yes, 2004
This paper describes novel uses of synchrotron radiation in examining porosity distributions within porous media. Tomographic energy dispersive diffraction imaging and Tomographic X-ray fluorescence have been combined within one measurement method and ...

Scale-dependent covariance of soil physical properties above and below a soil horizon interface: Pedogenic versus anthropogenic influences on total porosity [PDF]

open access: yes, 2011
The basic unit of soil – the pedon – is described as the minimum, three-dimensional unit of soil representative of the variability of soil horizon dimensions and morphology.

Effects of Different Porosities on Shear Strength of Fiber Clay by Response Surface Methodology

open access: yesChemical Engineering Transactions, 2018
To study the effects of different factors (fiber length, fiber content and porosity) on the shear strength of fiber reinforced soil, the direct shear test of 3 levels and 3 factors was designed by response surface methodology (RSM) to explore the effects

Addition Pinus massoniana fallen wood improved the growth of Plagiomnium acutum in a substrate cultivation

open access: yesScientific Reports, 2022
Soilless culture has been widely used in horticultural plant production, but little research has been done on bryophyte. In this study, we selected a cultivation substrate mixed and proportioned with garden soil, granular soil, grass charcoal soil ...

Study on soil water characteristics of tobacco fields based on canonical correlation analysis

open access: yesWater Science and Engineering, 2009
In order to identify the principal factors influencing soil water characteristics (SWC) and evaluate SWC effectively, the multivariate-statistical canonical correlation analysis (CCA) method was used to study and analyze the correlation between SWC and ...

Tillage and crop rotation effects on soil carbon and selected soil physical properties in a Haplic Cambisol in Eastern Cape, South Africa

open access: yesSoil and Water Research, 2020
The effects of tillage and crop rotation on the soil carbon, the soil bulk density, the porosity and the soil water content were evaluated during the 6th season of an on-going field trial at the University of Fort Hare Farm (UFH), South Africa.
