Research

Soil Health & Carbon Dynamics
Understanding how management practices influence soil organic carbon, nutrient cycling, and long-term soil health across agricultural and dryland systems.

Applied Agronomy & Crop Production
Evaluating crop, soil fertility, nutrient, and water management strategies to improve crop productivity, resource-use efficiency, and resilience across diverse production systems.

Cover Crops & Sustainable Cropping Systems
Evaluating cover crops, perennial systems, compost, and other climate-smart practices for improving soil function while maintaining crop productivity.

Greenhouse Gas Emissions
Investigating soil COâ‚‚ and Nâ‚‚O dynamics and how agricultural management can reduce emissions while increasing soil carbon storage.

Agricultural Systems Modeling
Using process-based models, including DayCent, APSIM, DSSAT, DNDC, and CERES-Maize, to evaluate crop productivity, soil carbon, greenhouse gas emissions, and management scenarios.

Climate Resilience & Food Security
Exploring how climate, soil fertility, management practices, and broader socioeconomic pressures affect agricultural productivity and food-system resilience, particularly in Sub-Saharan Africa.

Extension & Agricultural Outreach
Translating research into practical, evidence-based information for farmers, agricultural professionals, and other stakeholders through field demonstrations, educational programs, digital resources, and direct engagement.
