What is a major benefit of using a GPS system in farming?

Using a GPS system in farming offers the significant advantage of precise field mapping and efficient resource management. This technology enables farmers to accurately map their fields, which aids in planning and optimizing crop yields. By utilizing GPS data, farmers can determine the best planting patterns, manage irrigation systems more effectively, and apply fertilizers or pesticides in a targeted manner. This not only maximizes crop output but also minimizes waste and reduces environmental impact.

Additionally, the precision that GPS provides allows for better tracking of equipment and resources, leading to more effective resource allocation and lower operational costs. While other options mention advantages such as weather updates or labor reduction, they do not encapsulate the comprehensive impact that precise mapping and management have on the overall farming process and productivity.
