Dr. David C. Weindorf currently serves as Associate Vice President in the Office of Research & Innovation (ORI), Professor, and BL Allen Endowed Chair of Pedology in the Department of Plant and Soil Science. Dr. Weindorf holds a B.S. in Range Management, M.S. in Soil Science (geochemistry minor), and Ph.D. in Agronomy from Texas Tech University (TTU). In his research career, Dr. Weindorf has focused extensively on the development of new applications for proximal sensors, particularly portable X-ray fluorescence (PXRF) spectrometry, and visible near infrared diffuse reflectance spectroscopy (VisNIR DRS) for soil survey and environmental quality assessment. A considerable component of his research features international engagement with ongoing research in Brazil, China, India, Romania, Italy, and South Africa. Dr. Weindorf and his research team have published more than 150 peer reviewed research papers on topics ranging from classical pedology and proximal sensing applications to optimized land use management techniques.

Session Name: CCREF Supported Research Results: Air Emissions, Soluble Salts, Wetland Restoration

Session Time: Wednesday, January 29, 4:15 to 5:45 PM

Presentation Title: Understanding Soluble Salts in Compost

Presentation Description: Salinity represents a key chemical property which has strong implications for the overall use and value of compost products. However, confusion exists with regards to many aspects of salinity. This presentation will elucidate the important differences between salinity and sodicity, salinity as a contributor to cation exchange capacity (CEC), salinity tolerances of various plant species, and optimal levels of salinity in composted products. Additionally, units of salinity will be discussed, along with both classical and contemporary methods for compost salinity characterization.
