Technical Abstract: Soils data can be used to establish nutrient distribution at a selected site; however, soil sampling is labor intensive, costly, and selection of sampling sites may be difficult. This study was conducted to determine if methods developed for the management of saline soils can be applied to a vegetative treatment area (VTA) utilized to control feedlot runoff. Soil conductivity maps were generated at a VTA site. A software package, ESAP, developed by the Soil Salinity Lab at Riverside, CA was used to determine soil core locations and to estimate constituent distribution across the VTA. Tests were conducted to determine the ability of the ESAP program to estimate soil sample constituent values based on a subset of the soil conductivity and soil analysis data. Initial results indicated the method has good predictive ability based on a relatively small number of soil sampling sites. Additional work is underway to validate the methodology for alternative runoff control systems.
