Biography & Education

Biography

Dr. Augustine Obour is an Assistant Professor of Soil Science at Kansas State University Agricultural Research Center, Hays. A native of Ghana, Obour earned a bachelor’s degree in Crop Science from the Kwame Nkrumah University of Science &Technology, Ghana. He holds a master’s degree in Agronomy and a Ph.D in Soil and Water Science from the University of Florida.

His expertise is in soil and nutrient management with emphasis in tillage and nutrient management interactions in dryland cropping systems. He worked as a research scientist for the University of Wyoming from 2010 to 2013. He joined Kansas State University in May 2013.

Research

Augustine Obour’s research efforts are focused on developing soil management and agronomic production practices which protect soil, water, and air resources while sustaining crop yields and maintaining soil and environmental quality. Specific research goals are:

  • Develop oilseed and bioenergy feedstock production recommendations for western Kansas.
  • Investigate soil fertility and nutrient management issues in dryland (water-limited) cropping systems.
  • Investigate the interaction among tillage, cropping sequence and nutrient management and evaluate their impacts on crop productivity, nutrient cycling, carbon sequestration and overall soil health.
