What is one of the primary goals of using aerial applications?

Maximizing crop yields through effective pest control is a primary goal of using aerial applications. Aerial application allows for the swift and efficient delivery of pesticides, fertilizers, and other agricultural inputs directly to the crops. This method can cover vast areas quickly, which is particularly advantageous in large farming operations. By accurately targeting pests and diseases at critical growth stages, aerial applications help to minimize crop loss and improve overall health, leading to higher yields.

In contrast, minimizing the use of machinery in farming does not directly relate to the specific benefits of aerial applications; rather, it's more about the efficiency of methods used. Ensuring crops grow at the same height is more related to cultural practices in crop management rather than the application technique itself. Increasing the number of flights in a season is not inherently a goal of aerial applications; efficiency and effectiveness in pest and nutrient management are the key focuses.
