Assistant Professor Soil Chemistry
Department of Plant and Soil Science
Theophilus Udeigwe is an Assistant Professor of Environmental Soil Chemistry in the Department of Plant and Soil Science, Texas Tech University. Dr. Udeigwe holds a B. Agric (Soil Science) from the University of Nigeria, Nsukka, and an M.S. and a Ph.D. in Environmental Soil Chemistry (minor: Civil/Environmental Engineering) from Louisiana State University. Prior to joining Texas Tech University, Dr. Udeigwe was an Assistant Professor-Research at the Northeast Research Station, Louisiana State University AgCenter.
Dr. Udeigwe is currently a reviewer for four international journals, as well as the United States Department of Agriculture (USDA), and an active member of three professional organizations in the fields of agriculture and environmental sciences. Of interest he has secured over $0.6M of external grants from various competitive sources within the past five years. Dr. Udeigwe has also designed and taught over 20 course sessions in soil science, soil fertility and nutrient management, and environmental soil chemisty at undergraduate and graduate levels, both live (on campus) and online (distance) within the past three years.
Dr. Udeigwe’s program has strong international components with a major focus on developing countries. He has recorded significant international collaborations/activities in Egypt, Kenya, South Africa, Jordan, and China with 10 of his peer-review scientific publications resulting from these collaborations. He was recently awarded a prestigious Carnegie African Diaspora Fellowship by the Institute of International Education (IIE), sponsored by the Carnegie Cooperation of New York, to assist in enhancing the quality of higher education in Africa. Dr. Udeigwe has also won grants from the US Department of Agriculture (USDA) and US Agency for International Development (USAID) programs aimed at hosting and training scholars from Africa and have mentored/mentoring students and post-doctoral fellows from Egypt, Ghana, Liberia, Brazil, Syria, and Germany.
Dr. Udeigwe’s research focuses on the following:
I. Soil, water, and environmental chemistry
-Chemistry and fate of pollutants (organic and inorganic) and wastes in soil/water systems
-Soil management: Chemistry and reuse of waste materials for remediation purposes
II. Soil fertility and nutrient management
-Micronutrient fixation kinetics and modelling
-Agricultural management practices impacts on soil and environmental quality
-Chemistry of nutrients in agroecosystems
-Row crop production (soybean, cotton, corn, and sorghum)
-Irrigation: Development of cPHP has encountered an Access Violation at 025973CDrop coefficients for irrigation purposes
Findings from Dr. Udeigwe’s studies have been shared through 24 peer-review scientific publications, 25 abstracts, 7 technical reports, and 10 other presentations.
