Research Project: Calibration and Validation of In Situ Soil Moisture Sensors at Marena Oklahoma

Location: Hydrology and Remote Sensing Laboratory

Project Number: 8042-13610-030-053-S
Project Type: Non-Assistance Cooperative Agreement

Start Date: Sep 1, 2022
End Date: Aug 26, 2027

Soil moisture sensor technology is constantly evolving, and new sensors are developed each year. This agreement supports field work related to the maintenance and scaling of new in situ sensors at an existing testbed which contains many current technologies. Work with Oklahoma State University to evaluate the quality and accuracy of new in situ soil moisture monitoring instrumentation in a rangeland field. Large scale sampling of soil moisture and co-location of a variety of soil moisture sensor technologies will be implemented in a rangeland field on Oklahoma State University property under the management of their Range Research Station. Physical collection of soil moisture samples and characterization of the field on a routine basis for the term of 5 years will be the primary objective.

The cooperative work proposed here will assess the accuracy and representativeness of the soil moisture studies included in the project, based upon physical collection of soil moisture. ARS will direct the research testbed, leading the investigation and analysis of the results. OSU will be providing local logistical support for the testbed including site maintenance and communications support for the instrumentation.
