Yield map
A geospatial visualization that illustrates the variations in crop production across a field, generated by monitoring equipment during the harvesting process.
Также говорят: yield data map, productivity map
Yield maps are created using GPS-enabled sensors on harvesters to record the precise amount of grain harvested at every point in the field. This data acts as a foundation for precision agriculture, enabling farmers to identify high-performing and underperforming areas within their crop land.
These maps are essential for planning variable rate applications of fertilizers and seeds for subsequent seasons. By comparing yield data with historical trends, agronomists can diagnose specific issues, such as soil compaction, pest damage, or nutrient deficiencies, and apply corrective measures tailored to the needs of each zone.
A common error is failing to calibrate yield monitoring systems annually, which leads to significant data inaccuracy and flawed decision-making. Furthermore, relying solely on yield maps without correlating them with soil testing data or topographic information often results in incomplete insights and ineffective field management strategies.
