Physical Properties of Soil

2012
Physical properties of soil include color, texture, structure, porosity, density, consistence, temperature, and air. Colors of soils vary widely and indicate such important properties as organic matter, water, and redox conditions. Soil texture, structure, porosity, density, and consistence are related with types of soil particles and their arrangement.

The Soil. Physical, Chemical and Biological Properties

2016
This chapter provides a basic description of soil properties and processes, stressing the concept that the soil is a dynamic entity where complex interactions among its biological, chemical and physical components take place. All these components and properties determine the functioning of the soil for different purposes; this functioning is included ...

The Physical Properties of Soil

1964
A sample of soil taken from the field will contain mineral particles of very different sizes. There may be sizeable stones in it which have to be removed in order to obtain a homogeneous sample on which to conduct soil investigations. This is unfortunate because the field behaviour of a soil may be markedly affected by the presence of stones or large ...

Physical Properties of Soils

1999
Soil texture can be defined as the size and proportion of the soil particles—sand, silt, and clay—that are present in a soil. . . . Sand is the largest—from 0.05 to 2mm—and considered coarse texture; consists of angular spheres or cubes. Silt is intermediate—from 0.002 to 0.05mm—and considered medium texture; consists of properties between sand and ...

Soil Physical Properties in Reclamation

1991
To provide coordinated direction for reclamation research in Alberta, the need to review the current understanding and the role of soil physical properties in soil disturbance related activities was identified. Surface coal mining, pipeline and wellhead construction, oil sands extraction, timber harvesting, and agricultural production activities alter ...

Physical Properties of Allophane Soils

1977
Publisher Summary This chapter provides a comparison of the physical properties of allophane soils with the properties measured for soils with crystalline clay minerals. Allophone soils are the soils having observed properties common to soil materials, which arise from weathering of pyroclastics.

Physical Properties of Soils

1992
The physical properties of a soil give insight as to the identification of the soil and the determination of its characteristics and load response. These properties can be determined by performing a laboratory analysis on undisturbed soil samples obtained during the test boring process, as described in Article 3–6.
