Short Biography

Dr. Khaled Ibrahimi is an assistant professor of Soil Science at the Higher Agronomic Institute of Chott-Mariem, The University of Sousse, Tunisia. He graduated with a degree in Soil Science and Environment in 2001 from the National Agronomic Institute of Tunisia. Then, he earned his Master’s degree in sustainable management of arid zone resources in 2003 from the same academic institution. From the year 2005 until 2007 he worked as a soil scientist in the National Center for Agronomic Studies where he had the opportunity to work in teams that included engineers from various disciplines. In March 2011, he received his Ph.D. in Soil Physics and Soil Hydrology, Department of Biological and Environmental Engineering, Graduate School of Agricultural and Life Science, The University of Tokyo, Japan. He then continued working at the same University as a postdoctoral researcher before he was appointed as an assistant professor at the University of Sousse in January 2013. His research interests broadly encompass soil physics, soil hydrology, environment, resource management in arid and semi-arid areas as well as usage of GIS and remote sensing tools for development and sustainability studies. He has a strong interest as well in combining experiments with quantitative models to explore the complex physical and chemical processes associated with unsaturated flow and transport across variable land use and scales.

Over the years, cultivation using sustainable tillage practices has gained significant importance, but the impact of tillage on soil water infiltration is still a concern for landowners due to the possible effects on crop yield. This study investigates the impact of different tillage managements on the infiltration rate of sandy clay loam soil under a semiarid environment. Field experiments were conducted in Chott Mariem Sousse, Tunisia. The tillage practices consisted of three treatments, including a tine cultivator (TC, 16 cm), moldboard plows (MP, 36 cm) and no-tillage (NT). Three infiltration models, Kostiakov, Philip and Horton, were applied to adjust the observed data and evaluate the infiltration characteristics of the studied soils. Comparison criteria, including the coefficient of determination (R2), along with the root mean square error (RMSE) and mean absolute error (MAE), were used to investigate the best-fit model. The results showed that moldboard plowing enhanced soil infiltration capacity relative to tine cultivation and no-tillage treatments. The mean saturated hydraulic conductivity was highest under MP, while it was lowest in NT, with 33.4% and 34.1% reduction compared to TC and MP, respectively. Based on the obtained results, Philip’s model showed better results with observed infiltration due to a higher R2 (0.981, 0.973 and 0.967), lower RMSE (3.36, 9.04 and 9.21) and lower MAE (1.46, 3.53 and 3.72) recorded, respectively, for NT, MP and TC. Horton’s model had a low regression coefficient between observed and predicted values. It was suggested that the Philip two-term model can adequately describe the infiltration process in the study area.
