Autor: Cathy A. Seybold, Zamir Libohova, David Lindbo, S. D. Peaslee, Skye Wills, Phillip R. Owens, Dylan Beaudette, Kabindra Adhikari

Publikováno v: European Journal of Soil Science. 70:185-199

Statistical validation of spatial predictions of soil properties requires assessment of errors against measured values. The objective of this study was to assess the size of errors in the measurement of soil pH from different sources in the United St

Publikováno v: Journal of Soil and Water Conservation. 73:411-421

Soil organic matter (SOM) has been known to hold water and be an important factor in contributing to the available water-holding capacity (AWHC). Recently, however, there have been overestimates of this amount. The objective of this research was to r

Soil Survey

Autor: Cathy A. Seybold, Zamir Libohova

Publikováno v: Soil Science. 182:1-8

Soil survey is an ongoing process from initial soil mapping through soil survey updates. A national model of linear extensibility percent (LEP) is needed to improve this process. The objective of this work was to develop and validate models for estim

Soil Systems for Upscaling Saturated Hydraulic Conductivity for Hydrological Modeling in the Critical Zone

Autor: Zamir Libohova, Doug Wysocki, Skye Wills, Phil Schoeneberger, Cathy A. Seybold, Phillip R. Owens, Laura C. Bowling, Candiss O. Williams

Publikováno v: Vadose Zone Journal, Vol 17, Iss 1 (2018)

Successful hydrological model predictions depend on appropriate framing of scale and the spatial-temporal accuracy of input parameters describing soil hydraulic properties. Saturated soil hydraulic conductivity () is one of the most important propert

Using Soil Survey to Assess and Predict Soil Condition and Change

Autor: Zamir Libohova, Joel R. Brown, Linda Scheffe, Cathy A. Seybold, Skye Wills, David L. Hoover, Curtis J. Talbot, Candiss O. Williams

Publikováno v: Progress in Soil Science ISBN: 9783319433936

Soil survey organizes the landscape into units with common soil properties, characteristics, and classification. Soil survey units can be used to predict soil behavior and thus are useful for making management decisions and evaluating soil change. Tr

Effects of Precipitation on Nonpoint Source of Alkaline Earth Element Contamination to Surface Waters in the US Great Plains

Autor: M. A. Elrashidi, Cathy A. Seybold

Publikováno v: Soil Science. 179:314-323

Declining surface water quality is of great concern across the Great Plains. Recent changes in the earth’s climate can create abrupt changes in domestic weather that can alter the impact of nonpoint sources on water quality. A 2-year study (dry and

Predicting soil bulk density for incomplete databases

Autor: Cleiton H. Sequeira, Skye Wills, Cathy A. Seybold, Larry T. West

Publikováno v: Geoderma. 213:64-73

Soil bulk density (ρb) is important because of its direct effect on soil properties (e.g., porosity, soil moisture availability) and crop yield. Additionally, ρb measurements are needed to express soil organic carbon (SOC) and other nutrient stocks

Annual Precipitation and Effects of Runoff Nutrient From Agricultural Watersheds on Water Quality

Autor: Jorge A. Delgado, Cathy A. Seybold, M. A. Elrashidi

Publikováno v: Soil Science. 178:679-688

Declining surface water quality from agricultural nonpoint sources is of great concern across the Great Plains. Trends in the earth climate create abrupt changes in domestic weather (i.e., precipitation) that can alter the impact of the nonpoint sour
