Shioya

From Soil Testing

Shioya Series

 

Soil Classification: Carbonatic, isohyperthermic Typic Ustipsamments.

Description:
The Shioya series consists of deep and very deep, rapidly permeable, excessively drained soils on coastal strands. These soils formed in water-deposited coral sand. The depth to bedrock is 102 to 152 centimeters or more. Soil texture of top horizon is dominantly loamy sand, but it ranges to sand and sandy loam. Content of clay is 0 to 3.0 percent. The Shioya soil covers approximately 1.0 percent of Guam's total land area.

Suitability: This soil series is poorly suited to subsistence and commercial farming and homesite development. It is moderately suited to grazing. It is mainly used for recreation and wildlife habitat. The main limitations are the low available water capacity, high content of salt, low soil fertility, and droughtiness. Crops can be damaged by saline spray and wind. Crops should be planted as far from the open coastline as possible.
