Andres Patrignani installs soil moisture sensors at the OSU Range Research Station

in support of our Joint Fire Science Program funded research to understand the links

between soil moisture and wildfire in grasslands.



Welcome to the home page for the Oklahoma State University Soil Physics program. Here you can learn about our research and teaching activities and access information related to the discipline of soil physics.


Program Mission and Focus:

Our mission is to help people better understand and appreciate the soil, the soil water balance, and the surface energy balance so that we can more wisely manage and conserve the land and water with which we have been entrusted. Our primary focus is on multi-scale soil moisture monitoring and improved utilization of soil moisture data in agriculture, meteorology, environmental modeling, and drought adaptation.


An Urgent Appeal for Soil Stewardship



  1. New paper published in Vadose Zone Journal: Calibration and Validation of the COSMOS Rover for Surface Soil Moisture Measurement. Open access.
  2. Calibration and Validation of the COSMOS Rover:  Tyson Ochsner describes research on calibration and validation of the COsmic-ray Soil Moisture Observing System (COSMOS) rover for measurement of 0-5 cm soil moisture at spatial scales suitable for validating soil moisture satellites.
  3. Group member wins top award at SSSA annual meeting: Jordan Beehler won first place in the "Original Research Instrumentation" student poster competition with her poster on a method for analyzing green canopy cover.  The poster was coauthored by Andres Patrignani.
  4. New paper published in Journal of Atmospheric and Oceanic Technology:  New Soil Property Database Improves Oklahoma Mesonet Soil Moisture Estimates.
  5. Group members win top awards at OWRRI Symposium:  Andres Patrignani won first place and Sonisa Sharma won second place in the student poster competition at the 2013 Oklahoma Water Resources Research Institute (OWRRI) Research Symposium.
