TYPE LOCATION: Island of Maui, Maui County, Hawaii; Paia Quadrangle; 800 feet southwest of Haleakala Highway and 0.7 mile southeast of Haliimaile Road intersection in field number 228, Maui Pineapple Company Plantation; lat. 20 degrees 51 minutes 08 seconds N. and long. 156 degrees 21 minutes 24 seconds W. (Old Hawaiian Datum).
RANGE IN CHARACTERISTICS: Depth of soil is more than 60 inches. A few pebbles and cobbles are in some pedons. Mean annual soil temperature is 68 degrees F.
The A horizon has hue of 5YR or 7.5YR, value of 2 or 3 moist or dry, and chroma of 2 or 3 moist and 2 through 4 dry.
The B horizon has hue of 5YR or 7.5YR, value of 3 or 4 dry, and chroma of 2 or 3 moist and 2 through 4 dry. It is silty clay or clay.
COMPETING SERIES: (This needs updating.) These are the Kolekole, Pohakupu, and Kunia series. Kolekole and Pohakupu soils have oxidic mineralogy and mean annual soil temperatures of more than 72 degrees F. Kunia soils have mean annual soil temperatures of more than 72 degrees F.
GEOGRAPHIC SETTING: The Haliimaile soils are on uplands at elevations ranging from 500 to 2,000 feet. Slope is 3 to 15 percent. The soils formed in volcanic ash overlying residuum weathered from basic igneous rocks. The average annual precipitation ranges from 30 to 50 inches. Mean annual temperature is about 71 degrees F., average January temperature is 68 degrees F, and average July temperature is 74 degrees F.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Hamakuapoko, Keahua, Pane, and Paia soils. Hamakuapoko soils have an argillic horizon. Keahua soils have a fine-silty control section. Pane soils have an ashy control section.
DRAINAGE AND PERMEABILITY: Well drained; medium runoff; moderately rapid permeability.
USE AND VEGETATION: These soils are used for growing sugarcane and pineapple. Natural vegetation is guava (Psidium guajava), indigo (Indigofera suffruticosa), false vervain (Stachytarpheta cayannensis), koa haole (Leucaena glauca), lantana (Lantana camara), Natal redtop (Tricholaena repens), and yellow foxtail (Setaria geniculata).
DISTRIBUTION AND EXTENT: Island of Maui, Maui County, Hawaii. This series is of small extent, about 6,500 acres.
MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: Davis, California.
SERIES ESTABLISHED: Soil Survey, Territory of Hawaii, 1949.
REMARKS:
FCC Classification: Cdhik.
Edit Log: 12/03 SN. Classification changed from Fine, kaolinitic, isothermic Ustoxic Humitropepts due to changes in Taxonomy. Horizon designations updated and volcanic ash parent material added.
