(12 to 15 inches thick)
B3--26 to 36 inches; dark reddish brown (5YR 3/3) extremely stony silty clay, reddish brown (5YR 4/4) dry; weak medium and fine subangular blocky structure; slightly hard, friable, sticky and plastic; common roots; many fine pores; few very fine black specks; 70 to 80 percent gray and light yellowish brown pebbles, cobbles and stones; strong delayed effervescence with hydrogen peroxide; neutral (pH 6.7); clear wavy boundary. (9 to 12 inches thick)
IIC--36 to 56 inches; dark brown (7.5YR 3/2) extremely stony silty clay, dark brown (7.5YR 4/4) dry; massive; slightly hard, firm, sticky and plastic; few fine and medium pores; 80 to 90 percent gray and light yellowish brown pebbles, cobbles and stones; strong effervescence with hydrogen peroxide; slight effervescence with hydrochloric acid on small pebbles; neutral (pH 7.1).
TYPE LOCATION: Island of Maui, Maui County, Hawaii, Lahaina Quadrangle; 70 degrees 51' 26" north latitude and 156 degrees 39' 28" west longitude; 50 feet east of field road and 1,800 feet northeast of State Highway 30 in field number MC-4 of Pioneer Mill Company plantation.
RANGE IN CHARACTERISTICS: Stoniness on the surface ranges from very stony to extremely stony. Pebbles, cobbles and stones range from 50 to 80 percent in the particle size control section. Mean annual soil temperature is 75 degrees F.
The A horizon has value of 2 or 3 moist, 3 or 4 dry and chroma of 3 or 4 dry.
The B horizon has chroma of 3 or 4 moist. It is silty clay or clay.
In some pedons stones are coated with lime in the C horizon.
COMPETING SERIES: These are the Kamaole, Kaupo and Keawakapu series. Kamaole soils have isothermic temperature regime. Kaupo and Keawakapu soils are underlain by fragmental Aa lava.
GEOGRAPHIC SETTING: The Wainee soils are on alluvial fans. Slope is 3 to 15 percent. Large man-made rock piles are common in the area. Elevation ranges from sea level to 1,000 feet. The soils formed in old alluvium from basic igneous material. The average annual precipitation ranges from 10 to 20 inches. Mean annual temperature is about 75 degrees F.; average January temperature is 72 degrees F.; average July temperature is 78 degrees F.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Pulehu and Wahikuli soils. Pulehu soils have a fine-loamy particle size control section. Wahikuli soils have a fine-textured control section and are 20 to 40 inches deep.
DRAINAGE AND PERMEABILITY: Well drained; medium runoff; moderate to moderately rapid permeability.
USE AND VEGETATION: These soils are used for sugarcane. The natural vegetation is mainly fingergrass (Chloris spp.), kiawe (Prosopis chilensis), nutgrass (Cyperus rotundus) and uhaloa (Waltheria indica).
DISTRIBUTION AND EXTENT: Island of Maui, Maui County, Hawaii. This series is inextensive, with a total of approximately 2,700 acres.
