Water Potential 301–How to Push Your Instruments Past their Specifications

undefined

Learn the skills needed to create a soil water characteristic curve with wet end and dry end data that actually match up in the middle.

Leo Rivera teaches the skills needed to create a soil water characteristic curve with wet end tensiometer data (Hyprop) and dry end dew point data (WP4C) that actually match up in the middle.

These techniques potentially make it possible for researchers to push their instruments past their specifications. Learn about issues surrounding these measurements, including the effects of hysteresis and changes in sample preparation methods required when you move into the wet range.

Presenter

Leo Rivera operates as a research scientist and Hydrology Product Manager at METER Group, the world leader in soil moisture measurement. He earned his undergraduate degree in Agriculture Systems Management at Texas A&M University, where he also got his Master’s degree in Soil Science. There he helped develop an infiltration system for measuring hydraulic conductivity used by the NRCS in Texas. Currently, Leo is the force behind application development in METER’s hydrology instrumentation including HYPROP and WP4C. He also works in R&D to explore new instrumentation for water and nutrient movement in soil.
