Kagman

From Soil Testing

Kagman Series

Soil Classification: Very-fine, mixed, nonacid, isohyperthermic Oxic Paleustalfs.

Description:
The Kagman series consists of deep and very deep, well drained, moderately slowly permeable soils on uplifted limestone plateaus. These soils formed in sediment overlying argillaceous limestone. Depth to bedrock is 150 to 200 centimeters or more. Soil texture of top horizon is silty clay loam, clay loam, silty clay, or clay. Content of clay is 60 to 90 percent. The Kagman soil covers approximately 1.4 percent of Guam's total land area.

Suitability: This soil series is well suited to subsistence farming. The main limitation is droughtiness late in the dry season. It is susceptible to compaction during the rainy season. Mechanical tillage and vehicle traffic should be avoided when the soil is wet. It is moderately suited for homesite development, grazing and commercial farming. It can be used for wildlife habitat and watershed.
