Respondents noted agricultural crops airside at 50% of airports, groundside at 39.5% and within 8 km of the airport reference point at 81.6%. Despite the possibility of extreme risk, depending upon the specific crop, less than a quarter of airports have attempted to influence adjacent agricultural crop management. Because agricultural crops can vary
in the hazards posed to aircraft operations, depending on the type of crop, agricultural practices implemented, and distance from the airport, the airport needs to address the specific risks posed by the agricultural crops present.
