Ylig

From Soil Testing

Ylig Series

 

Soil Classification: Fine, mixed, acid, isohyperthermic Aquic Ustifluvents.

Description:
The Ylig series consists of very deep, somewhat poorly drained, moderately slowly permeable soils in seep areas on concave hillsides and in drainageways. These soils form in alluvium derived from weathered tuff and tuff breccia. The soils are hummocky in some areas. The depth to bedrock is 114 centimeters or more. Soil texture of top horizon is silty clay or clay. Content of clay is 50 to 70 percent. The Ylig soil covers approximately 1.9 percent of Guam's total land area.

Suitability: This soil series is moderately suited to subsistence farming and grazing. It is poorly suited for commercial farming. Crops that can be grown during the dry season include beans, watermelons, and Chinese and head cabbages. Most areas of this soil series are poorly suited to banana and other fruit trees that are sensitive to wetness. The main limitations are the included area of poorly drained soils (wetness), soil acidity, and droughtiness late in the dry season. It is used as watershed and wildlife habitat. The use of this soil series as wildlife habitat and watershed can be enhanced by maintaining existing wetland vegetation.
