Boettinger Lab Group
Pedology is a branch of soil science focusing on the formation, morphology, and classification of soils as bodies within the natural landscape. Pedology seeks to understand how the properties and distribution patterns of soils worldwide have developed along with broader landforms, biogeochemical environments, and habitats of living organisms. Through their understanding of the causes and magnitudes of soil variations, pedologists help to broaden knowledge of the surface of the Earth and promote conservation of the soil resource.

Spatial Prediction of Surface Soil Temperature Classes from Soil Climate Analysis Network (SCAN) Data
Utah NRCS installed 35 SCAN sites throughout the state in 2007 and 2010. SCAN sites record soil moisture and temperature data at several depths in the soil profile. In addition, the SCAN sites also record selected climatic data. The goal is to eventually use SCAN data to predict soil climate across the state of Utah at different temporal scales (annual, monthly, daily). We are focusing the initial phase of this project on predicting annual surface soil moisture classes in a subset area of MLRA 28A, extending from the Utah-Nevada border to the Wasatch front.
Annual surface soil moisture data will be calculated from SCAN, SNOTEL, and active weather stations in the subset area and used as training data for the classification. Predictor variables will be a combination of remote sensing and DEM derivative data, surface soil property data from SSURGO products, vegetation data from SWGap data, and other possible data sources. The Random Forests classifier will be used to predict annual surface soil moisture classes across the subset area. This project is in the preliminary stage with no results to report, but will be complete by the end of 2011.
Applying the Optimum Index Factor to Multiple Data Types for Soil Survey
Digital soil mapping in production soil survey requires simple, straight-forward methods that can be easily implemented into daily activities of soil mapping. The Optimum Index Factor (OIF) was developed by Chavez et al. (1982; 1984) as a method for determining the three-band combination that maximizes the variability in a particular multispectral scene. The OIF is based on the amount of total variance and correlation within and between all possible band combinations in the dataset. Although the OIF method was developed for Landsat TM data, the concept and methodology are applicable to any multilayer dataset. We used the OIF method in a subset area of the initial soil survey of the Duchesne Area, Utah, USA, to help determine which combination of data layers would be most useful for modeling soil distribution. Unique multiband images created from layers of multiple data types (elevation and remote sensing derivatives) were evaluated using the OIF method to determine which data layers would maximize the biophysical variability in the study area. A multiband image was created from the optimum combinations of data layers and used for classification and modeling in ERDAS Imagine. The output from the classification and modeling are being evaluated as pre-maps for soil mapping activities in the study area.

Land Cover Classification from Landsat Imagery for Mapping Dynamic Wet and Saline Soils
Wet and saline soils have been recognized as an important and complex component of wetland ecosystems in arid environments. Analysis and classification of remotely sensed spectral data is an effective method for discerning the spatial and temporal variability of soils. The East Shore Area (ESA) of the Great Salt Lake soil survey update is focused on updating soil map units containing wet and saline soils. The ESA provides a unique environment for the use of remotely sensed spectral data for map unit refinement because of low relief and a large extent of soils that are wet and saline to various degrees. Map units in the ESA containing wet and saline soils were updated and refined using Landsat 7 imagery. Five land-cover classes are related to dominant soil types that vary in soil wetness, salinity, calcium carbonate concentration and vegetation cover type. Supervised classification of the imagery was performed using the five land cover classes. The final classification resulted in 14 land cover classes, including nine additional classes that help describe the variability in the original five classes. The classification results were validated using visual inspection in the field, a priori knowledge of the area and an error matrix. The results of the classification were used to enhance original soil map units and calculate map unit composition in the final soil mapping process. This information was then incorporated into the updated soil map. Temporal variation in land cover classes has the potential to be considered in map-unit refinement to reflect the dynamic nature of the margins of the Great Salt Lake, Utah.

Soil Survey Using Traditional and Landscape Analysis Methods – Grand Staircase-Escalante National Monument, Utah
The overall goal of this research was to develop methodology to advance the soil survey of the Circle Cliffs area of the Grand Staircase-Escalante National Monument. A soil survey of the Circle Cliffs area was completed using traditional soil survey methods, and then enhanced using GIS-based methods. A lithosequence of soils was also examined to enhance the understanding of arid soil genesis and the soil-landscape relationships in the Circle Cliffs area. GIS was shown to be beneficial for soil survey data analysis, and was useful for quantifying and validating map unit concepts. The lithosequence study showed that soils formed in lithified parent material exhibited varying degrees of soil development, and the soil formed in non-lithified parent material appeared to be polygenetic. GIS was very useful for accelerating the soil survey, and may be applicable in other remote areas for examining soil-landscape relationships.

Laureen is researching parent material, soils, and landscape characteristics associated with shrubby-reed mustard, an endangered plant species endemic to the Uinta Basin in Utah. A decision making tool for use in identifying shrubby-reed mustard potential habitat will be developed.Shrubby Reed-Mustard Habitat: Parent Material, Soil and Landscape Characteristics
Shrubby reed-mustard, or Glaucocarpum suffrutescens, is an endangered perennial shrub endemic to the Uinta Basin in northeast Utah. Only seven populations of shrubby reed-mustard have been identified. The area where the plant grows is rich in natural gas and oil deposits, as well as oil shale. Oil wells already dot the landscape, and there is significant concern that further development of these resources will threaten the continued existence of shrubby reed-mustard. Determination of the parent material, soil and landscape characteristics associated with shrubby reed-mustard habitat is imperative to facilitate conservation management.
Our shrubby reed-mustard project seeks to identify the characteristic environment of this brightly colored plant. Extensive field observation, soil sampling with laboratory characterization, and descriptive and statistical analysis of data are all required to fully characterize the habitation of shrubby reed-mustard. Based on those determinations, we will develop a decision-making tool for identifying potential habitat for this endangered species. Validation of the decision making tool will be performed. It may be possible to use derivatives of remotely sensed spectral data (e.g., Landsat 7 ETM+, ASTER) and topographic data (e.g., digital elevation models) to predict potential habitat at a larger spatial scale.
Initial field characterization and soil profile sampling was conducted in October 2010. Soil profiles were sampled from three different locations within the Uinta Basin. Probably the most important field observation made regarding the soil where shrubby reed-mustard grew was the parent material. Shrubby reed-mustard grew exclusively in soils derived from shale. On the sites sampled where shrubby reed-mustard did not grow, but where other species existed, the soil parent material was sandstone. Laboratory characterization of soils collected is on-going. Data trends and statistical findings have yet to be determined from preliminary lab results.Characteristic shrubby reed-mustard habitat.
Further field characterization and sampling will resume in Spring 2011. Selection of spring sampling locations will be influenced by the results of the Fall 2010 characterization. Elucidation of parameters for plant re-establishment is imperative to the survival of shrubby reed-mustard, given the current and future development of the area where this plant is endemic.
Colby's research focuses on using Digital Soil Mapping techniques to elucidate the spatial scale at which soil varies across different landscapes. Colby's research also focuses on the different types of statistical models useful for predicting soil distribution and what these models tell us about pedogenesis.Predicting Soil Components and Value-Added Soil Information in Canyonlands National Park, Utah
What – We modeled Biological soil crust (BSC) class (classes 0-6), map unit component, ecological site, soil series, soil depth and surface texture class for Canyonlands National Park.
Why – BSC in arid ecosystems influence infiltration and erosion rates and are important for soil resource management. Hopefully these maps will be useful for Park Service Planning and be an additional value added product derived from NRCS mapping efforts.
We used Random Forests with 1000 trees and the default number of random variables.
Pedon information used as training data was obtained from the NRCS and cleaned (checked for correct spelling, etc.).
Biological soil crust classes were rounded to the nearest integer.
Distance between pedons was calculated and Pedons <90 m apart were manually selected and removed from the training dataset.
Several concerns about this dataset exist: many pedons are photo interpreted and many do not have complete data entered.
NASIS data was obtained from the National Park Service but it came in a format for AnalysisPedon which was prohibitively difficult to use.
OOB errors for each predicted attribute are listed in the PDF Out-of-bag_Errors. While overall OOB error is informative it is often more useful to look at the individual class OOB errors. OOB error is highly dependent upon class size.
Maps of BSC class and associated probability are in Biol_soil_Crust_maps.pdf. Other predicted soil attributes are in OtherMaps.pdf. Variable importances for each prediction are in Variable Importance.pdf.

Jeremiah is conducting an ecosite evaluation using vegetative field data and Predictive Soil Mapping for one of the Fort Bliss ranges. The goal of the project is to predict soil distribution to support ecological sites. The research site is located in Otero Mesa, New Mexico.
Fort Bliss Soil Survey 2010
The purpose of this project is to establish an ecosite evaluation of the study area for future monitoring as to the effects of military training in the area. The project was initiated by the Department of Defense and is headed by the USDA from the Joranada Experimental Range office at New Mexico State University in conjunction with Utah State University. The project area has been historically used for grazing with little or no development and no impact on the landscape other than livestock and wildlife. The area has been maintained and the livestock has been managed by the BLM for the last few decades. The military is now expanding training operations into the area to include field exercises by troops on the ground. They will conduct operations by foot and vehicle in open ground areas. Training will also include the construction of temporary encampments that will result in high traffic areas. The future monitoring of the site will include possible changes to vegetation and soil conditions.
The location of this site is Otero Mesa, New Mexico. The mesa is situated at the northern extreme of Fort Bliss and 22 miles east northeast of Orogrande, New Mexico. The mesa is at an elevation of ≈5100 ft. which is approximately 900 ft. above the surrounding basin floor. The area is accessible by route 506 from state highway 54. The generalized landform of the project area is alluvial fans/remnant fans in the upland which give way to lowlands of basin floor with limited drainage. The soil temperature regime is mesic and has a soil moisture regime of aridic boarding on ustic. The parent material for this area is limestone derived alluvium.
One hundred sample locations were chosen with conditioned Latin hypercube based off of environmental covariates which included but not limited to topographic, geologic and remotely sensed spectral data. At each sample location the genetic horizons were sampled and described to a depth of one meter unless lithic contact or a limiting layer was encountered. The pedons were classified to the family level using field sampling techniques. The ecosite was evaluated from soil type and vegetative cover that was recorded on site to state and phase.
At the completion of this phase of the project we will be able to predict soil distribution using random forest classification and produce a preliminary predictive map that encompasses soil and ecosite type. The preliminary prediction is subject to change with results from ongoing laboratory analysis. Currently the mineralogy class of majority of soils sampled are of a mixed mineralogy class but analysis could easily place soils into a carbonatic classification.
