Prof. Obed M. Lungu

Department of Soil Science
Academic Qualifications:
  • Ph.D. (Calif.-Davis),
  • M.Sc (Newcatle Upon Tyne)
  • B.Agric. Sc. (UNZA)

Was invited to join the Department of Soil Science as a Staff Development Fellow after graduating in 1975. He worked up the academic ladder at UNZA and was promoted through two ranks during 1977- 1988, to Senior Lecturer in 1989, Associate Professor in 2001 and to Professor in 2009. Served as Head of Department several terms and as Dean of the School of Agricultural Sciences 2000-2004 before retirement in 2004. During 1992 -1996 was on leave of absence from UNZA and lectured at Limpopo University (1992-1993) and served as Rector at Madzivhandila College of Agriculture (1993 -1996), South Africa. He was tasked to manage and integrate the Bantustan institution into the mainstream new South Africa. From 2004 to 2014 he was on UNZA/Golden Valley Agricultural Research Trust (GART) joint appointment and served at GART as Soil Management Specialist under the R & D Department, researching and promoting sustainable agricultural technologies.

Research Interests
  • Amelioration of soil acidity—Diagnosis of soil acidity and determination of economical lime requirements for highly weathered tropical soils.
  • Exploitation and development of local fertilizer resources involving evaluation of phosphate rock (PR) processed products for agronomic effectiveness.
On-going Research
  • Micronutrient bio-fortification of staple crops; Soil carbon and nutrient cycling through biomass and soil amendments for improved soil productivity.
