Dynamic Soil Survey Team

Digital Soil Survey photo.Overview

The Soil and Plant Science Division (SPSD) currently provides aggregated soil survey products to customers for use in land and conservation planning. SPSD recognizes the need for enhanced soils information for current and future customer needs. Dynamic Soil Survey (DSS) is an evolving approach to soil survey that will incorporate recent and long-standing advances in pedology, ecology, and hydrology with improvements in digital technology.

  • North Woodstock, NH (Hubbard Brook Experimental Forest) US Forest Service
    St. Johnsbury MLRA office has completed the first draft of the digital soil map. Soil Plant Science Division and U.S. Forest Service have an interagency agreement to have a post doc working on Hubbard Brook and Coweta.
     
  • Otto, North Carolina (Coweeta Experimental Forest) US Forest Service
    Waynesville MLRA office has completed the first draft of the digital soil map. Forest Service post doctorial staff is running the Regional Hydro-Ecological Simulation System (RHESSys) model to develop the relationship of soil moisture to the watershed water budget. Additional onsite soil moisture data will improve the model and should allow changes in forest management to project changes in soil moisture. Understanding impacts of forest management on soil moisture will be important in forest management.
     
  • Manhattan, Kansas
    Kansas State, Oklahoma State, Texas A&M Universities and USDA Agricultural Research Service evaluating soil moisture sensors and their ability to work in a variety of soils. Five-year study beginning in 2022. Documentation of sensor selection, calibration and data interpretation so researchers, irrigation managers understand measurement errors of sensors affected by soil properties.
     
  • Clay Center Kansas (Kansas NRCS Staff and Kansas State University)
    Four watersheds with H-flumes evaluating conservation practices Conservation Crop Rotation, Residue and Tillage Management, No-till, Nutrient Management and Cover Crop. Nine-year study began in 2021. Understanding how the soil moisture budget is altered by changes in these conservation practices. Data will be used to support conservation planning decisions.
     
  • El Reno Ok, Agricultural Research Service (ARS)
    Discussion has begun with the ARS staff at El Reno Oklahoma on possible site selection for agricultural production.
     
  • Moscow, Idaho University of Idaho
    SPSD staff are evaluating a quantitative comparison of soil moisture regimes and geomorphology. Five-year study beginning in 2022. Data from study will enhance use of soil taxonomy related to the xeric soil moisture regime. This data will assist in quantification of the boundary between xeric, ustic and udic. Important for forest and range management.
     
  • Stephenville, Texas
    Stephenville MLRA staff are seeking to improve the interpretation of seasonal water tables in several soil series in MLRA 84. Began in FY2020 it is a ten-year study. Document the presence or absence of seasonal water tables and to improve the understanding of catenary water relationships to nonpoint source pollution in the West Cross Timbers.
