Dr. Jeremiah M. Okeyo Profile

Education

1.PhD in Soil Science, University of Wyoming: August 2010 – May 2014
Thesis Title: The Effect of Conservation Agriculture Practices on Soil Quality and Crop Productivity under Contrasting Smallholder Farming Systems in Western Kenya and Eastern Uganda.
Research Synopsis: Sustainable farming practices are required to address the persistent problems of land degradation and declining crop productivity in sub-Saharan Africa. In this study, we assessed the impact of conservation agriculture (CA) practices in comparison to conventional farmer practices on soil quality indicators and crop yields under shortand long-term trials in western Kenya and eastern Uganda. Soils were sampled and analyzed for total and labile soil carbon and nitrogen pools, aggregate stability and infiltration capacity. Our results indicate that reduced tillage combined with crop residues enhanced physical soil quality but better targeting of CA approaches is necessary to enhance crop productivity.
Research Interests: My research interests are in application of sustainable soil, water and nutrient management practices to smallholder farming systems in sub-Saharan Africa and other developing countries with the aim of meeting the dual goals of enhanced crop productivity for food security and resilience to climate change. In particular, I am interested on how we can adapt sustainable farming practices to the highly diverse agro-ecological and socio-economic conditions within which smallholder farmers operate.
