<div style='text-align:Left;'><div><div><p><span>The National Cooperative Soil Survey - Soil Characterization Database (NCSS-SCD) contains laboratory data for more than 65,000 locations (i.e. XY coordinates) throughout the United States and its Territories, and about 2,100 locations from other countries. It is a compilation of data from the Kellogg Soil Survey Laboratory (KSSL) and several cooperating laboratories. The data steward and distributor is the National Soil Survey Center (NSSC). Information contained within the database includes physical, chemical, biological, mineralogical, morphological, and mid infrared reflectance (MIR) soil measurements, as well a collection of calculated values.

Soil Data Access (SDA) web services for querying data</span></p><p><span>4. Direct download of the entire database in several formats.</span></p><p><span>Data at each location includes measurements at multiple depths (e.g. soil horizons). However, not all analyses have been conducted for each location and depth. Typically, a suite of measurements was collected based upon assumed or known conditions regarding the soil being analyzed. For example, soils of arid environments are routinely analyzed for salts and carbonates as part of the standard analysis suite. Standard morphological soil descriptions are available for about 60,000 of these locations. Mid-infrared (MIR) spectroscopy is available for about 7,000 locations. Soil fertility measurements, such as those made by Agricultural Experiment Stations, were not made. Most of the data were obtained over the last 40 years, with about 4,000 locations before 1960, 25,000 from 1960-1990, 27,000 from 1990-2010, and 13,000 from 2010 to 2021. Generally, the number of measurements recorded per location has increased over time. Typically, the data were collected to represent a soil series or map unit component concept. They may also have been sampled to determine the range of variation within a given landscape.</span></p><p><span style='font-family:"Avenir Next W01", "Avenir Next W00", "Avenir Next", Avenir, "Helvetica Neue", sans-serif; font-size:16px;'>Individual Metadata [</span><a href='https://inventory.data.gov/dataset/69f36f6d-8212-47a7-bdb9-72025f849e6a/resource/9aebddcb-f3f1-4e81-a058-8c317675ec26/download/ncss-sc_iso19115_version3_20241209.xml' target='_blank' rel='nofollow ugc noopener noreferrer'>XML</a><span style='font-family:"Avenir Next W01", "Avenir Next W00", "Avenir Next", Avenir, "Helvetica Neue", sans-serif; font-size:16px;'>]</span><span></span></p></div></div></div>

The National Cooperative Soil Survey (NCSS) Soil Characterization Database (SCD) is composed of soil laboratory measurements made by the Kellogg Soil Survey Laboratory (KSSL) and other NCSS Cooperator laboratories. It includes data that may or may not represent the central concept of a soil series or map unit and pedons sampled to estimate the range of soil properties within a series or a landscape. Sample preparation and analytical procedures are described in Soil Survey Investigations Report, No. 42, Natural Resources Conservation Service (NRCS), 1992. Users unfamiliar with a given soil may want to consult a knowledgeable soil scientist to determine how well the data represents a soil series. Furthermore, the database has not been edited to remove all of the erroneous or sometimes misleading data. For research purposes, all such data are retained in the database. Users are responsible for the assessment of the accuracy and applicability of the data.
These data are used to develop and support the range in characteristics for a soil series or soil components in the Soil Survey Geographic (SSURGO) data. In other cases, the data has been used as training data for research projects and developing digital soil maps.
Data tables with a brief description included are as follows:
lab_analysis_procedure: The Analysis Procedure table is a lookup table that contains information about the analysis procedure. The analysis procedure is the basic analytical method applied to a prepared sample. This procedure may be applied to different sample preparations, but the default size-fraction is the most commonly used size-fraction. An analysis may have more than one procedure, one of which is chosen by the analyst to complete the analysis.
lab_analyte: The Analyte table is a lookup table that contains information about an analyte (primary result of an analysis by a procedure). The laboratory information management system (LIMS) uses this data to format the data and to provide abbreviations and units of measure for reporting the data.
lab_area: The Area table is a lookup table containing the list of valid NRCS areas, both current and obsolete for country, county, soil survey area (SSA) and major land resource area (MLRA). Note that a soil survey area code is a concatenation of a U.S. State Federal Information Processing Standards (FIPS) code and a soil survey area number. Since this table is intended to record only U.S. and U.S. territory soil survey areas, every soil survey area code in this table should be unique.
lab_calculations_including_estimates_and_default_values: The Calculations Including Estimated and Default Values table contains the results of calculations using measured, estimated and default values.
lab_chemical_properties: The Chemical Properties table contains the results of the analysis of chemical properties of the soil that are measured by the KSSL and cooperating university laboratories.
lab_combine_nasis_ncss: The Combine NASIS NCSS table is a linkage between National Soil Information System (NASIS), pedon morphological and the lab data. This table stores information about locations, layers, or horizons of a pedon that has had samples submitted to the KSSL at the National Soil Survey Center (NSSC) or one of the various laboratories at NCSS cooperating universities. Data is periodically transferred from the KSSL database to this table.
lab_layer: The Layer table contains information about the layer, including the field identifier, horizon designation, reporting, and depths. Layer in the LIMS can be a true soil horizon or a reporting layer that does not correspond to the traditional soil horizon.
lab_major_and_trace_elements_and_oxides: The Major and Trace Elements and Oxides table contains major and trace elements, total oxides, x-ray data and the method codes related to the methods used.
lab_method_code: The Method Code table relates a non-connotative method code with the preparation, instrument, size fraction, analyte, procedure (if any) and calculation algorithm (if any) represented by that method code.
lab_mineralogy_glass_count: The Optical Mineralogy Glass Count table provides the raw data for the sample. The table contains the type of optical count, the size fraction and replicate number.
lab_mir: The Mid-infrared Spectroscopy table stores the spectra absorbance values for samples that have these results. Spectroscopy is the study of the interaction between matter and electromagnetic radiation. It is based on the principle that molecular vibrations and electronic transitions associated with soil constituents absorb light while interacting with radiation.
lab_mir_wavelength: The Wavelength Metadata lookup table stores the wavelength range collected for the MIR spectra (lab_mir) data table.
lab_pedon: The Pedon table stores general information about the pedon. The pedon is associated with a site.
lab_physical_properties: The Physical Properties table contains the results of analysis of physical properties of the soil measured by the KSSL and cooperating university laboratories.
lab_preparation: The Preparation table contains the information about the type of preparation, size of the original and final fractions prepared, default container type and preparation sort order.
lab_rosetta_key: The Rosetta Key table stores values returned from ROSETTA model, a USDA software program, which implements five hierarchical pedotransfer functions for the estimation of water retention, as well as the saturated and unsaturated hydraulic conductivity.
lab_site: The Site table stores information about the site location and where the samples or pedon originated.
lab_webmap: The Webmap table is used to develop a webmap to use for the interactive display of geographic information pertaining to laboratory information. The interactive map offers a national database of soil characterization data, allowing location of pedons spatially. Pedons are the smallest unit of soil containing all the soil horizons of a particular soil type. Users can access lab data about a specific pedon by selecting a pedon location within the interactive map. To access the new interactive map, select this offsite link image. You can also view the map on the Soil Lab Data Mart (LDM) website (bottom left of page) here: https://ncsslabdatamart.sc.egov.usda.gov/.
lab_xray_and_thermal: The X-ray Diffraction and Thermal Data table contains the raw data for each mineral in the sample.

<div style="text-align:Left;"><div><div><p><span>Although strict quality-control measures are applied, the NSSC does not warrant that the data are error free. In some cases, the measurements are not within the applicability range of the laboratory methods. For example, dispersion of clay is incomplete in some soils by the standard method used for determining particle-size distribution. Soils producing incomplete dispersion include those derived from volcanic materials or that have a high content of iron oxides, gypsum, carbonates, or other cementing materials. The determination of clay minerals by x-ray diffraction is relative. Measurements of very high or very low quantities by any method are not very precise. Other measurements have other limitations in some kinds of soils. Such data are retained in the database for research purposes. Some of the data were obtained from cooperating laboratories within the NCSS. The accuracy of the location coordinates has not been quantified but can be inferred from the precision of their decimal degrees and the presence of a map datum. Some older records may correspond to a county centroid. When the map datum is missing it can be assumed that data prior to 1990 was recorded using NAD27, and WGS84 was used after 1995. For detailed information about methods used in the KSSL and other laboratories refer to Soil Survey Investigation Report No. 42 - https://www.nrcs.usda.gov/sites/default/files/2023-01/SSIR42.pdf. For information on the application of laboratory data, refer to Soil Survey Investigation Report No. 45 - https://www.nrcs.usda.gov/sites/default/files/2022-10/SSIR45.pdf. Users unfamiliar with any terms or methods should consult their NRCS State soil scientist. Terms of Use: This dataset is not designed for use as a primary regulatory tool in permitting or citing decisions but may be used as a reference source. This is public information and may be interpreted by organizations, agencies, units of government, or others based on needs; however, they are responsible for the appropriate application. Federal, State, or local regulatory bodies are not to reassign to the Natural Resources Conservation Service or the National Cooperative Soil Survey any authority for the decisions that they make. The Natural Resources Conservation Service will not perform any evaluations of these data for purposes related solely to State or local regulatory programs.</span></p></div></div></div>
