Saipan

From Soil Testing

Saipan Series

Soil Classification: Fine, mixed, isohyperthermic Oxic Haplustalfs.

Description:
The Saipan series consists of deep and very deep, moderately permeable, well drained soils on uplifted limestone plateaus. These soils formed in sediment overlying porous coralline limestone. Depth to bedrock is 100 to 200 centimeters or more. Soil texture of top horizon is clay, silty clay, clay loam, or silty clay loam. Content of clay is 35 to 60 percent. The Saipan soil covers approximately 0.6 percent of Guam's total land area

Suitability: This soil series is moderately suited for subsistence farming, commercial farming, grazing, and homesite development. With proper management, (fertilizers and drip irrigation) most vegetables and some fruit trees can be grown throughout the year. The main limitation of the Saipan soil is the low soil strength.
