  KST Soil Moisture Regimes
The soil moisture regimes are defined in terms of the level of ground water and in terms of the seasonal presence or absence of water held at a tension of less than 1500 kPa in the moisture control section.
The aquic (L. aqua, water) moisture regime is a reducing regime in a soil that is virtually free of dissolved oxygen because it is saturated by water.
The ustic (L. ustus, burnt; implying dryness) moisture regime is intermediate between the aridic regime and the udic regime.

Moisture farmers are located on dry planets where water is scarce, such as the planet Tatooine on the Outer Rim.
A moisture ratio is a ratio that compares the mass or volume of air to the mass or volume of moisture contained in that air.
Soil moisture is the ratio of the volume of the voids to the volume of water, and thus ranges from zero, when there is no water in the soil, to one, when all the voids are filled with water and there is no air.

A regime (occasionally spelled "régime", particularly in older texts) is the set of rules, both formal (for example, a Constitution) and informal (Common law, cultural or social norms, etc.) that regulate the operation of government and its interactions with the economy and society.
In science, a regime can mean a particular state of affairs where a particular physical phenomenon or boundary condition is significant, such as "the superfluid regime" or "the steady state regime".
Regime is the name of a band from Pembrokeshire, United Kingdom.

 Populating Taxonomic Moisture Class and Subclass in NASIS | NRCS Soils
A taxonomic moisture subclass that is not “typic” reflects a taxonomic intergrade or extragrade.
Some soils having a particular moisture regime are transitional to another regime (intergrades) or are grading away from the regime to which they are assigned (extragrades).
For the Mollic subgroup, the taxonomic moisture subclass is understood to be typic because the Aeric subgroup (the name of which indicates the only other moisture subclass to be used with aquic) precedes the Mollic subgroup in the key, leaving typic as the only remaining choice.
