• M.S., Soil Science, Texas Tech University (1971)
• B.S., Soil Science, Texas Tech University (1969)

Dr. Wayne Hudnall's research interests are in soil genesis, classification, mineralogy, hydric soils, wetland delineation, and agronomic requirements. Other areas of expertise include soil mapping, geomorphology, nutrient management, requirements for septic system installations, remote sensing, and GIS. He has been awarded research grants to study the remediation for drastically disturbed land, identification of delineation of hydric soils and wetlands, and carbon sequestration within the coastal marsh. His recent research projects include soil and vegetation resilience index for environmental management, geostatistical analysis of sediments characteristics in reservoirs, and soil and temperature relationships to Vertisols.

His job duties include all phases of the Cooperative Soil Survey Program and supporting field and laboratory research in soil genesis, morphology, and classification in cooperation with the USDA-NRCS and the Louisiana Agricultural Experiment Station. Before coming to Texas Tech, Dr. Hudnall taught for 3 years at West Texas A&M University and 25 years at Louisiana State University. He has served as the chairperson of the USDA-NRCS International Committee on Soil Moisture and Temperature Regimes and a Fellow of Soil Society of America.
