Single crystals, or arrangements of crystals of relatively pure fractions of the plasma that do not enclose the s-matrix of the soil material but form coherent masses; their morphology is consistent with their formation and present occurrence in original voids in the enclosing soil material.
Industry:Earth science
An organism whose optimum temperature for growth falls in an intermediate range of approximately 15 to 35°C. Synonymous with "mesophile. \
Industry:Earth science
Arrangement of strata inclined at an angle to the main stratification. This is a general term having two subdivisions; cross-bedding, in which the cross-strata are thicker than 1 cm, and cross-lamination, in which they are thinner than 1 cm.

Industry:Earth science
An instrument in the form of a cylindrical rod with a cone-shaped tip designed for penetrating soil and for measuring the end-bearing component of penetration resistance. The resistance to penetration developed by the cone equals the vertical force applied to the cone divided by its horizontally projected area.
Industry:Earth science
Mollisols that have a udic soil moisture regime with mean annual soil temperatures of 8°C or more. Udolls have no calcic or gypsic horizon, and are not saturated with water for periods long enough to limit their use for most crops.
Industry:Earth science
Remains of fish excreta and similar materials that occur in some organic soils.
Industry:Earth science
Bacteria able to convert organic phosphorus into orthophosphate.
