We recently interviewed a drone pilot on this subject. You can learn about how Eric brings on new clients in the AG sector by checking out the interview here: https://uavcoach.com/agricultural-drone-imagery/
Some strategies he calls out include:
highlighting cost avoidance and the potential for increases in yields
focused conversations on the imagery and the information it can provide as opposed to conversations about the drone hardware and equipment
pro bono work to get started
This seems to be a challenge for many in the AG sector, but I think Eric brings out some helpful points in the interview.
