About

I am a Professor of Soil Chemistry and Fertility with a lot of interest in Soils, Agriculture, Environment and Development. I hold professional memberships with a lot of professional bodies. I have participated in various capacity building conferences such as the 40thAnnual Conference of the Soil Science Society of Nigeria, University of Calabar, March 14-18, 2016. I have handled several services within and outside the University of Uyo. My publications in journals, books and public discourse are highly rated and some can be downloaded here and redistributed where necessary.Learn more...
