Biography and Research Information
OverviewAI-generated summary
Helen C. S. Amorim is a postdoctoral researcher at the University of Arkansas, focusing on soil science and the application of advanced spectroscopic techniques. Her research interests include the mechanisms of soil organic carbon retention, conservation agriculture's impact on soil quality, and the utilization of industry by-products as fertilizers. Amorim has investigated soil quality indices under various long-term management practices, including conservation pasture and cropping systems, as well as burning, irrigation, and fertility management. Her work also explores the composition and potential use of insect frass as an organic fertilizer within circular economy frameworks, examining its effects on forage and soil health. Amorim's publications have addressed global trends and drivers of C:N ratios in soils and particle-size fractions, indicating preferential nitrogen sorption by clays. She collaborates with researchers at the University of Arkansas, including Amanda J. Ashworth and Gerson Laerson Drescher.
