Soil science
Soil structure
Earth science; Soil science
The combination or arrangement of primary soil particles into secondary units or peds. The secondary units are characterised on the basis of size, shape, and grade (degree of distinctness).
Adsorption
Earth science; Soil science
The process by which atoms, molecules, or ions are taken up from the soil solution or soil atmosphere and retained on the surfaces of solids by chemical or physical binding.
Flow velocity of water in soil
Earth science; Soil science
The volume of water transported per unit of time and per unit of cross-sectional area normal to the direction of water flow.
Pore-size distribution
Earth science; Soil science
The volume fractions of the various size ranges of pores in a soil, expressed as percentages of the soil bulk volume (soil particles plus pores).
Transmission zone
Earth science; Soil science
That part of a soil profile which is behind the wetting front during infiltration and does not increase in water content during further infiltration.
Heat of immersion
Earth science; Soil science
The heat evolved on immersing a soil, at a known initial water content (usually oven dry) in a large volume of water.
Specific water capacity
Earth science; Soil science
The change of soil-water mass content with change in soil-water matric potential.
