Soil Physics Workshop – Syllabus
Soil Hydrology with the Stevens HydraProbe Soil Sensor
This year at the Meteorological Technology World Expo 2018 event in Amsterdam Stevens is excited to present a 2-hour Soil Physics Workshop. The interactive lecture will be hosted by Steven’s own Soil Scientist & Geochemist / Certified Professional Hydrologist Keith Bellingham.
Course Summary
Knowledge of soil moisture and the measurement of soil moisture help society answer some important questions about drought, flood forecasting, greenhouse gas emissions, food security and crop production. This course will focus on the science of the analytical measurements of soil water content and water potential. From an “applications in the field” perspective to a more theoretical approach, this course provides tools, information, and insight for users of soil moisture sensors and soil moisture data, with a focus on the HydraProbe.

The Stevens Soil Resource Guide
Developed by B. K. Bellingham, Soil Scientist at Stevens, this is an excellent resource for anyone installing soil moisture sensors and interpreting soil moisture data.
In the summer of 2019, Stevens Water Monitoring Systems and the Oregon State University (OSU) Hermiston Agricultural Research and Extension Center (HAREC) partnered to evaluate
We’re happy to announce the publication of our Soil Resource Guide. Written by the soil experts at Stevens, it contains a wealth of information and will
