The Soil Temperature and Moisture Profiles (STAMP) System provides half-hourly measurements of soil moisture, soil temperature, soil conductivity, soil permittivity, and plant water availability at three profiles of five depths. The system also measures one-minute accumulations of precipitation. The STAMP systems use soil-type-specific calibrations for each depth for each SGP Extended Facility, including Okmulgee EF21. Most of the STAMP systems were installed in late 2015, with the remaining three being installed in early 2016.
