The sub- <br />soil is a stony loam about 6 inches thick. The underlying material is <br />basalt stones and cobble. <br />Surface runoff is medium and erosion hazard is moderate. <br />Estimated pH: 6.6 - 7.3. <br />Depth of usable topsoil: 0 - 8 inches. <br />Depth to seasonal high watertable: ~ 6.0 ft. <br />Flood hazard: None. <br />Capability unit: VIe, non-irrigated (8A). <br />~rrre, aon-irrigated (8F). <br />Range site: Stony loam. <br />
