Dr. Salma Fatnassi | Soil | Soil Health Advocate Award

National Institute of Research in Rural Eaux and Forets | Tunisia

Salma Fatnassi is a researcher in soil science and environmental geochemistry whose work focuses on understanding the behavior of micronutrients and trace metals in agricultural systems irrigated with treated wastewater, generating important knowledge on soil–water–plant interactions and contaminant mobility. Her research involves designing and managing collaborative studies that assess soil contamination risks, nutrient cycling, and the environmental sustainability of wastewater reuse in agriculture. She is skilled in soil and water sampling, geochemical laboratory techniques, environmental monitoring, and the application of statistical and spatial tools for interpreting complex environmental datasets. With strong expertise in data analysis using R, Excel, ArcGIS, and SPSS, she evaluates metal bioavailability, transport pathways, and ecological impacts with high analytical rigor. Her scientific contributions include 4 published documents, 24 citations, and an h-index of 3, reflecting her growing influence in the field. Salma Fatnassi has also strengthened her methodological foundation through training in bibliographic research, pedagogy, statistical analysis, and innovative water treatment technologies, enabling her to support interdisciplinary and international research collaborations. Overall, her work advances sustainable soil and water management, improves understanding of trace element dynamics, and supports evidence-based environmental protection strategies in agricultural ecosystems.
