STEVENS HYDRA PROBE ENHANCES ACCURACY FOR SOIL MOISTURE MONITORING IN LOAM CONDITIONS
Portland, Ore., April 24, 2007 – Stevens Water Monitoring Systems’ Hydra Probe soil moisture sensor continues to make advances in performance and now comes with a new loam setting feature that covers more of the soil triangle spectrum. The new firmware calibration model is based on the work of Mark Seyfried from the USDA-ARS and Keren Humes from The University of Idaho. The new loam setting is a calibration model now programmed into the Hydra Probe that was determined from a variety of different soils taken from different depths. Loam is a term used to describe a soil that contains mixtures of sand, silt and clay. This new calibration curve will serve to make the Hydra Probe even more accurate over a wider range of soil types. The soil textures where the Loam setting would be applicable include:
The loam setting has also been shown to work well in some clays and in soils that have high organic matter contents such as an A horizon. Information about this new loam calibration was also published in the Vadose Zone Journal, a peer-reviewed scientific publication.
