Agricultural Yield Mapping
Definition
Yield mapping uses GPS and sensors on harvesters to record crop productivity variations across a field. Data is visualized as heatmaps to guide soil treatment, irrigation, or seed selection.
Application
Farmers identify low-yield zones for soil testing or drainage improvements. Agri-lenders assess risk using historical yield data. Commodity traders predict regional production.
FAQ
1. What sensors are used in yield mapping?
Grain flow sensors, moisture meters, and GPS receivers.
2. How is yield data cleaned?
Outliers from machinery stops or overlaps are filtered using software like SMS Advanced.
3. Can yield maps predict climate impact?
Yes, combined with weather models, they forecast drought or flood effects.
4. What’s the ROI of yield mapping?
Studies show 10–15% input cost savings via targeted fertilizer use.
