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...
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 ...
Soil texture is the soil property that has been demonstrated to be very well predicted by sensing technologies. Its importance in the assessment of soil's capability to sustain biomass production is supported by differences in yield productivity in soils with different textures. For example, the abo...
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 becomes seve...
With respect to the hydraulic properties, the cover beds vary mainly in texture, especially regarding coarse clasts, and bulk density (Kleber et al., 1998b). An important property, which is unique to rock that weathers to platy clasts, is its imbricate structure. This is the result of the...
The experimental soil had a sandy loam texture, and had been used in rice cultivation prior to the experimental period. The properties of the organic fertilizer, vermicompost, and soil were determined according to Lu (2000) and are summarized in Table 1. Table 1 The properties of organic ...
000 years because the leaching process is speeded by acidic materials. Parent materials heavy in texture require a much longer time to develop into soils because of an impeded downward flow of water. Soils develop more slowly in dry regions than in humid ones. Soils on steep slopes often ...
Soil and water losses were determined from sieved air-dry samples of five Iowa soils varying in texture using a laboratory rain simulator with a 3-m. drop fall, a 4.85 to 5.00 mm. drop diameter, and an intensity ranging from 3.43 to 6.78... WC Moldenhauer,DC Long - 《Soil Science Soc...
The termKs,str[mm h−1] is the saturated hydraulic conductivity due solely to the presence of soil structure andKs,texequals the saturated hydraulic conductivity determined by soil texture. It is noteworthy that using a superposition of VG functions also for the hydraulic conductivity represents...
{\rho _0}}\), whereφ = pore space,ρ = fine fraction bulk density,ρ0 = density of the solid phase. Soil texture was determined with the pipette method54. Of the three variables sand, silt and clay, we retained soil clay content as an explanatory variable. A list of...
