The numerical difference between the liquid and the plastic limit or, synonymously, between the lower plastic limit and the upper plastic limit.
Industry:Earth science
The amount of work required to raise a body a specified height in a gravity field. Gravity head is expressed as energy per weight and is equal to the distance Z, of a measurement point in the soil above an arbitrary reference height (z). Gravity potential is expressed as energy per volume and is equal to the product of the distance raised, Z, the water density, ρ and the gravitation constant, g (ρgZ)
Industry:Earth science
The excreta of animals, with or without an admixture of bedding or litter, fresh or at various stages of further decomposition or composting. In some countries may denote any fertilizer material.
Industry:Earth science
The height of the dominant and codominant trees (not suppressed during development) at an index age, commonly 25, 50, or 100 years. Used in conjunction with volume tables, site index provides an indication of relative site production.
Industry:Earth science
The effective diameter of a particle measured by sedimentation, sieving, or micrometric methods.
Industry:Earth science
The orderly arrangement of atoms in a crystalline material.
Industry:Earth science
The content of water, on a mass or volume basis, remaining in a soil 2 or 3 days after having been wetted with water and after free drainage is negligible.
Industry:Earth science
Ultisols that have low or moderate amounts of organic carbon, reddish or yellowish argillic horizons, and a udic soil moisture regime. Udults are not saturated with water for periods long enough to limit their use for most crops.
