Precision Agriculture: How Nebraska Farmers Are Helping Transform African Farming

When most people think of precision agriculture, they picture vast Midwestern fields with GPS-guided combines and variable-rate planters. But the principles behind these technologies — doing more with less, making data-driven decisions, and optimizing every input — are perhaps even more relevant for African agriculture, where margins are tighter and resources more constrained.

From the Great Plains to the Great Rift Valley

At SASFA, our co-founders Jay Reiners (Secretary/Treasurer, U.S. Grains Council) and Brandon Hunnicutt (Director, Nebraska Corn Board) have spent over 50 combined years farming in Nebraska — one of America’s most technologically advanced agricultural states. Over three decades, they have witnessed and adopted the full arc of precision agriculture: from early GPS guidance systems to today’s data-driven crop analytics platforms.

This experience gives them a practical perspective on what works, what doesn’t, and — critically — what can be adapted for different growing conditions. Not every technology that succeeds on a 2,000-acre Nebraska corn farm will translate directly to a 5-hectare plot in Tanzania or Zambia. The art is in knowing which principles are universal and which implementations need rethinking.

Five Precision Ag Principles That Cross Borders

1. Soil Health Monitoring — Whether you are using a $200,000 soil sampling rig or a $50 handheld pH meter, understanding your soil is the foundation of productive farming. Research from the International Food Policy Research Institute (IFPRI) consistently shows that soil testing leads to better input decisions regardless of farm scale. SASFA’s Field Assessment service begins with GPS-referenced soil sampling and historical yield analysis to identify productivity zones in every field.

2. Variable-Rate Application — Applying the right amount of input in the right place reduces waste and can improve yields. In resource-scarce environments, this matters even more. The FAO’s soils program has documented how even basic site-specific management can reduce fertilizer costs while maintaining output.

3. Weather-Based Decision Making — Satellite weather data and mobile-accessible forecasting tools are increasingly available across Africa. Services like CGIAR’s climate services are enabling data-driven planting decisions in regions that previously relied solely on traditional weather knowledge. This is especially valuable in Ethiopia and other countries facing increasing climate variability.

4. Record Keeping and Analysis — The shift from intuition to data doesn’t require expensive software. Mobile apps and simple spreadsheets can drive meaningful improvements. Studies from CIMMYT have shown that farmers who track inputs and outputs make measurably better decisions over time. Rwanda’s strong digital infrastructure makes this leap especially practical for cooperatives and commercial operations.

5. Scout Before You Spray — Integrated pest management reduces chemical costs and environmental impact. Drone scouting is becoming more accessible even in developing regions, with organizations like FAO’s Plant Production and Protection Division supporting adoption of IPM practices across Sub-Saharan Africa.

Where Precision Agriculture Pays Off Fastest

Not every operation should adopt precision agriculture today. The economics depend on the operation’s scale, the variability of its soils, the cost of inputs being optimized, and the skill base available to maintain new systems. Generally speaking, precision pays back fastest where:

• Input costs are high relative to crop value — fertilizer, seed, and crop protection costs that get wasted under uniform management
• Field variability is real — soils, drainage, and historical yield differ across the operation
• Operator capacity exists — or can be developed through training and partnerships
• Reliable equipment service is available within a day’s travel

For commercial operations in Kenya’s Rift Valley, Ghana’s rice and oil palm sectors, and emerging medium-scale farms across the continent, these conditions are increasingly met. For smallholder farmers, precision principles still apply, but the toolkit looks different — soil moisture sensors, mobile advisory services, drone-based scouting at the cooperative level rather than per-farm.

The SASFA Approach

We don’t believe in technology for technology’s sake. Our consulting approach starts with understanding local conditions, available resources, and economic realities — then identifies which precision agriculture tools and practices can deliver the highest impact for the investment required. We have made every common mistake on our own Nebraska operations — the failed first try, the mismatched system, the technology that arrived too far ahead of the workflow. That hard-won experience is what makes our advisory work different.

Working alongside research partners including the University of Nebraska–Lincoln, the Daugherty Water for Food Global Institute, and the Nebraska Corn Board, SASFA helps governments, NGOs, and commercial operations evaluate which precision technologies are appropriate for their specific conditions, design phased adoption roadmaps, and build the local capacity that makes adoption stick.
