Hilo soil and landscape
Soil profile: A representative soil profile of the Hilo series; the State Soil of Hawaii. (Photos provided by Amy Koch, USDA-NRCS)
Landscape: Aerial view of an area dominated by Hilo soils showing a diversity of land uses, including orchards and cultivated crops.
The Hilo series was established in 1949 and was first mapped in Soil Survey of the Territory of Hawaii published in 1955. The Hilo series occurs on the Island of Hawaii, to the north of the town of Hilo. The Hilo soils are derived from volcanic ash and occur on the wet, rainy side of Mauna Kea volcano.
The Hilo series consists of deep, well drained soils that formed in material weathered from volcanic ash. Hilo soils are on ashfields and have slopes of 0 to 35 percent. The mean annual rainfall is about 3683 millimeters (145 inches) and the mean annual temperature is 22 degrees C (72 degrees F) or higher.
TAXONOMIC CLASS: Medial over hydrous, ferrihydritic, isohyperthermic Acrudoxic Hydrudands
Depth to bedrock: 112 to over 152 centimeters (44 inches to over 60 inches).
Soil moisture: The soil is typically moist but there may be occasional brief periods of dryness in the surface from 0 to 30 centimeters (0 to 12 inches) during the driest months of the year, usually June thru August.
Rock fragments: 0 to 20 percent cobbles in the first 102 centimeters (40 inches)
Soil temperature: 22 degrees C (72 degrees F) or higher
Surface fragments: 0 to 10 percent
USE AND VEGETATION: These soils are used for forest, wildlife habitat, building site development, recreation, orchard crops, agroforestry, and livestock grazing. Common vegetation is hilograss (Paspalum conjugatum), guinea grass (Urochloa maxima), California grass (Urochloa mutica) and strawberry guava (Psidium cattleianum).
DISTRIBUTION AND EXTENT: This series is along the Hamakua coast on the island of Hawaii. This series is moderately extensive with a total of about 30,000 acres.
