What can breaks in normal cultivation patterns indicate to the pilot?

Breaks in normal cultivation patterns can indicate hidden hazards to the pilot. These breaks might suggest the presence of obstacles or irregularities in the field that are not immediately visible. For example, if there are abrupt changes in surface texture or unexpected patterns of soil disruption, these can signal issues such as rocks, irrigation channels, or other obstacles that could pose risks during aerial application. Pilots must be alert to these signs, as flying over areas with hidden hazards can lead to accidents or equipment damage.

Contextually, while each of the other choices presents concerns that might arise during cultivation, they do not specifically relate to what breaks in cultivation patterns signify. Mechanical issues would follow signs of equipment malfunction, soil erosion is more related to visible deterioration of the land, and weed presence usually manifests through growth patterns, not necessarily as breaks in cultivation. Hence, the focus on hidden hazards is particularly relevant for flight safety and operational integrity.
