Research Interests

  • Nutrient cycling on smallholder farms in Africa – designing cropping sequences to align with farm socio-economic circumstances (legume –cereal sequences, intercropping, integrated soil fertility management)
  • Investigations on soil- water interactions through low cost practices that have potential for adoption by risk averse small farms in Africa
  • Soil organic carbon dynamics and cereal productivity along soil fertility gradients/toposequence
  • Africa Rising project
