How does aerial application reduce soil compaction?

Aerial application significantly reduces soil compaction by minimizing the need for ground vehicles, which can compress the soil. When crops require treatment with fertilizers or pesticides, using aerial methods eliminates the necessity for heavy machinery to traverse the fields.

Ground vehicles typically exert a considerable amount of weight on the soil, which leads to compaction and can hinder root growth, water infiltration, and overall soil health. By conducting these applications from the air, the risk of soil compaction is greatly diminished, allowing for healthier soil structure and improved conditions for crop growth.

The other options do not directly address soil compaction in the same way. For instance, the use of heavy machinery typically increases compaction rather than reducing it. The application of organic fertilizers and the improvement of drainage systems can benefit soil health and crop yield but do not specifically solve the problem of compaction related to ground traffic.
