Biography and Research Information
OverviewAI-generated summary
Amanda J. Ashworth is a soil scientist whose research focuses on soil health indicators, soil hydraulic properties, and microbial community structure. Her work investigates the relationships between soil properties, management practices, and environmental factors such as topography. Ashworth has published extensively on evaluating carbon indicators, aggregate stability, and selecting soil hydraulic properties as indicators of soil health. She has also explored the use of the Topographic Wetness Index as a proxy for soil moisture and investigated soil bacterial diversity in silvopastoral systems.
Her research extends to the potential use of insect frass as an organic fertilizer within circular economies and linking soil microbial community structure to carbon mineralization. Ashworth is a highly cited researcher with an h-index of 33 and over 200 publications. She has received significant federal funding as a Co-PI on an NSF grant focused on the phylogeny, systematics, and adaptation of marine epizoic diatoms. Ashworth leads a research group at the University of Arkansas at Fayetteville and collaborates with several researchers, including P. Moore, D. Philipp, Kelsey L.H. Greub, and Helen C. S. Amorim.
