State Soil Data Access (SDA) Report

An SDA-populated select list is used to pick a state and SSA which enables creation of a "Potential Baseball Infield Soil Source" based upon those selections. Baseball infields have been historically constructed with optimum drainage and particle size in mind. Baseball infield areas have a specified range of characteristics which this interpretation uses to identify soil map units with the highest potential for these materials. This table gives information about the soils as potential sources of soil material suitable for baseball field. Normal compaction, minor processing, and other standard construction practices are assumed. Criteria for this report is sand content between 60 and 65 percent and silt to clay ratio is between 0.75 to 1. Ideally, medium sand to total sand ratio should be greater than 0.5 Baseball infields have been historically constructed with optimum drainage and particle size in mind. Baseball infield areas have a specified range of characteristics which this interpretation uses to identify soil map units with the highest potential for these materials.
For more information about the table,

• areaname: The name given to the specified geographic area.
• areasymbol: A symbol that uniquely identifies a single occurrence of a particular type of area (e.g. Lancaster Co., Nebraska is NE109).
• chkey: A non-connotative string of characters used to uniquely identify a record in the Horizon table.
• claytotal_r: Mineral particles less than 0.002mm in equivalent diameter as a weight percentage of the less than 2.0mm fraction.
• cokey: A non-connotative string of characters used to uniquely identify a record in the Component table.
• compname: Name assigned to a component based on its range of properties.
• comppct_r: The percentage of the component of the mapunit.
• hzdepb_r: The distance from the top of the soil to the base of the soil horizon.
• hzdept_r: The distance from the top of the soil to the upper boundary of the soil horizon.
• musym: The symbol used to uniquely identify the soil mapunit in the soil survey.
• hzname: The concatenated string of four kinds of symbols (five data elements) used to distinguish different kinds of layers in the soil. (SSM)
• mukey: A non-connotative string of characters used to uniquely identify a record in the Mapunit table.
• muname: Correlated name of the mapunit (recommended name or field name for surveys in progress).
• musym: The symbol used to uniquely identify the soil mapunit in the soil survey.
• sandmed_r: Mineral particles 0.25mm to 0.5mm in equivalent diameter as a weight percentage of the less than 2 mm fraction.

The suitability of the material for specific purposes is not evaluated, nor are factors that affect excavation of the material. The properties used to evaluate the soil as a source of particle size are gradation of grain sizes (as indicated by the Unified classification of the soil), the thickness of suitable material, and the content of rock fragments. The ratings are for the whole soil, from the surface to a depth of about 6 feet.

Information in this table is intended for land use planning, for evaluating land use alternatives, and for planning site investigations prior to design and construction. The information, however, has limitations. For example, estimates and other data generally apply only to that part of the soil between the surface and a depth of 5 to 7 feet. Because of the map scale, small areas of different soils may be included within the mapped areas of a specific soil.

The information is not site specific and does not eliminate the need for onsite investigation of the soils or for testing and analysis by personnel experienced in the design and construction of engineering works.
