Dr. Kedir is an agri-environmental scientist. Currently a post-doctoral fellow and project manager (2020 to present) at the Memorial University of Newfoundland under the supervision of Prof. Adrian Unc. Dr. Kedir’s doctoral research investigated phosphorus dynamics in the podzolic soil converted from boreal forest to agriculture. He studied phosphorus adsorption and availability, suitable agri-environmental P tests and analyses techniques for the northern boreal agriculture. His work sheds light on the soil fertility test tools for boreal agriculture for sustainable financial and environmental benefits. Dr. Kedir’s research involves improving soil health and nutrient uptake in podzolic soil by integrating soil, plant science, and waste management knowledge. His research on environmentally sustainable nutrient recovery from local organic waste and agricultural utilization helps the local farming community improve podzolic soil productivity and explore alternative nutrient sources for plant production. Dr. Kedir and his team investigated the reutilization and integration of community, agriculture, and fishery-based organic wastes in the small community as a means of sustainable waste reduction and GHG emissions. Also, he assessed the potential to repurpose depleted potting soil for vegetable production in the GH. Currently, Dr. Kedir is the project manager and team member of the ongoing integrated soil health project for crop production in the northern boreal region, helping the farmers and scientific communities to better understand the expansion of agriculture into the northern boreal region and its effect on soil fertility, and soil-plant interactions.

Research interests:

  • Phosphorus dynamics in natural and northern agriculture soil and climate change effect.
  • Nutrient recovery and recycling from diverse organic waste and its utilization in improving soil health.
