Soil is a porous medium with different particle compositions that display irregular shapes and self-similar structures, and it exhibits fractal characteristics. Therefore, fractal theory has been applied to the study of soil characteristics1. Texture is determined by the distribution of different particle...
Briefly, soil texture was determined using a simple sifting and sedimentation-based approach47, and the pH of the soil was assessed in a 1:5 suspension (soil to distilled water). Organic matter was determined colorimetrically following oxidation with a combination of potassium dichromate and ...
The latter can be quantified as functions of soil water potential (Ψ) or soil water content, the form of these relations being strongly influenced by soil texture (Van Genuchten, 1980). Spatial heterogeneity of soil water and roots and the difficulty of measuring each of the resistances ...
It is because the degree and magnitude of soil compaction depend on soil strength, which is related to the mechanical strength of soil (determined by soil texture and soil organic matter (OM) content), tillage layer, and wetness of soil (Hamza & Anderson, 2005). The effect of compaction ...
As it is a surrogate for conductance from bare soil (Kelliher et al. 1995), gCn may be soil texture dependent. Show moreView chapterExplore book Soil Physics Quirijn de Jong van Lier, ... Paulo Ivonir Gubiani, in Encyclopedia of Soils in the Environment (Second Edition), 2023 Use of ...
It is mainly sandy backfill with pebbles. The uncontaminated control soil (Ctrl) was sampled in a kitchen garden, Gradignan, France. Both sandy soils were air-dried and sieved at 4 mm. Soil texture and physico-chemical parameters were determined with standard methods and a quality scheme by ...
Soil texture is defined as the distribution of mineral particles less than 2 mm in diameter (fine earth fraction): clay (<0.002 mm), silt (0.002–0.63 mm) and sand (0.063–2 mm).Particles larger than sand are considered coarse fragments, and include gravel (2–64 mm), cobbles (64 mm...
In this paper, SMCCs of undisturbed soil samples determined experimentally are compared with those provided by using PTFs. For this purpose we used Soil Water Characteristics from Texture software. Comparisons of the test results are made. Furthermore the usefulness of SWCT as a tool for ...
Soil texture was determined using the hydrometer method using 40 g of air dry soil. Soils were treated with hydrogen peroxide to remove organic matter prior to texture measurements. Soil organic matter content (%) was measured using loss-on-ignition by drying a 25 g sample at 105 °C...
The soil texture was determined by a fluid suspension method using a specialized hydrometer, based on Stokes’ law of particle dispersal83. RNA isolation and bacterial community fingerprinting analysis Total RNA was recovered from desert soil samples using an modified phenol-chloroform extraction ...
