Which of the following is NOT a primary component of a yield monitoring system?

In the context of yield monitoring systems used in agriculture, a soil sampler is not a primary component. Yield monitoring systems are designed specifically to measure and record the amount of crop harvest as it is being harvested.

Key components of a yield monitoring system include:

• Flow sensors, which measure the rate at which crop material is passing through the combine harvesters. This information is crucial for determining yield per unit area.

• GPS systems, which allow for spatial mapping of yield data, enabling farmers to understand the variation in yield across different parts of a field.

• Data loggers, which store the information collected from the flow sensors and GPS systems over time, allowing for data analysis and review.

While soil sampling is an important practice in agriculture for understanding soil health and nutrient levels, it is not a direct component of a yield monitoring system, which focuses on measuring the outputs during the harvesting process rather than assessing soil conditions. This distinction clarifies why soil samplers do not belong within the primary components of yield monitoring systems.
