HARSTINE SERIES Landscapeglacial drift plains Landformridges Teninoless than 50 percent sand in control section; 2C horizon with more than 60 percent rock fragments GEOGRAPHIC SETTING: SOIL SURVEY REGIONAL OFFICE (SSRO) RESPONSIBLE: Portland, Oregon In the United States, twelve major soil texture classifications are defined by the USDA.
The twelve classifications are sand, loamy sand, sandy loam, loam, silt loam, silt, sandy clay loam, clay loam, silty clay loam, sandy clay, silty clay, and clay. Soil textures are classified by the fractions of each soil separate (sand, silt, and clay) present in a soil.

Sand ranges in size Constant Head Permeability Test: 1) Assemble the permeameter and attach the manometer tubing to the side of the permeameter. 3) Measure the height of the compacted soil.
Web Soil Survey (WSS) provides soil data and information produced by the National Cooperative Soil Survey. It is operated by the USDA Natural Resources Conservation Service (NRCS) and provides access to the largest natural resource information system in the world.

Rock fragments are dominantly channers, flagstones, or gravel, Permeability classes and most references to permeability have been removed from the NSSH and replaced with the saturated hydraulic conductivity classes of the 1993 Soil Survey Manual.
The NSSH adopted the index surface runoff guide from the Soil Survey Manual, without reference to classes, as well as the guidelines for estimating saturated Land and soil judging requires careful attention to soil texture, color, drainage conditions, permeability, depth, stoniness or rockiness, slope and surface runoff. 1) physical, chemical, and mineral composition of the parent material Soil Testing Criteria.
