What type of yield monitoring technology utilizes sensors on harvesting equipment?

In-line yield monitoring systems are specifically designed to measure crop yield directly during the harvesting process. These systems employ sensors that are embedded in harvesting equipment, such as combines, to provide real-time data about the amount and quality of the crop being harvested. The sensors collect information on the flow of grain or other crops moving through the combine, allowing for immediate analysis of yield variability across different areas of the field.

This technology is essential for precision agriculture, as it enables farmers to optimize their harvesting practices, identify high-yield and low-yield areas within a field, and make informed decisions for future planting and resource allocation. The real-time feedback from in-line systems helps in zoning management practices and guides inputs for subsequent crop cycles to improve yield and reduce waste.

The other options represent technologies that serve different purposes. GPS tracking systems are primarily used for navigation and mapping, while drone surveillance technology focuses on aerial imagery for crop health assessment, and soil moisture sensors measure water levels in the soil rather than yield during harvest. Each of these contributes to agriculture but does not specifically address the direct measurement of yield during harvesting as in-line yield monitoring systems do.
