text: Soil Moisture Regime Major Characteristics Aquic Soil is saturated with water and virtually free of gaseous oxygen for sufficient periods of time, such that there is evidence of poor aeration (gleying and mottling); Common in wetlands Udic Soil moisture is sufficiently high year-round in most years to meet plant requirement; Common in humid regions Ustic Soil moisture is intermediate between Udic and Aridic regimes; generally, plant-available moisture during the growing season, but severe periods of drought may occur; Common in semi-arid regions Aridic Soil is dry for at least half of the growing season and moist for less than 90 consecutive days; Common in arid (desert-like) regions Xeric Soil moisture regime is found in Mediterranean-type climates, with cool, moist winters and warm, dry summers.
