An important characteristic of soil is particle size distribution (granular distribution or texture) or colour. Both agricultural and soil science properties are to a large extent determined by soil texture and colour. Determining the particle size and classification of the soil is essential for ...
Because soil is a particulate material，it is natural to consider the size of these particles and their effect on the behavior of the soil. Several different classification schemes are available， but the one published by ASTM ( American Society for Testing and Materials) is the most...

2.2. Classification of Particle Size Particle sizes are expressed as the average diameter of spheres of the same size. To calculate the molecular volume and size when the composition of molecular particles is known, we use the formula:
(øi+1/øi) is constant. Meanwhile, according to the United States Department of Agriculture classification of soil particle size, the soil size was partitioned into 3 grades, clay (0–2 μm), silt (2–50 μm) and sand (50–2000 μm). The soil organic matter (SOM) was ...
The different origin of tal parameters potentially useful for classification and prediction. The the various size fractions may explain the various scaling multifractal spectra of 30 PSDs covering a wide range of soil textural classes were analyzed. Parameters calculated from each multifractal domains ...
To study the fractal dimensions of the soil particle size distributions (PSDs) within different plantations (of Pinus densiflora, Quercus acutissima, Robinia pseudoacacia, and Larix kaempferi) and evaluate PSDs as an indicator of the likelihood of Robini
