UAS mapping, scouting, and stand counts are common now, but ag engineering plans operations under FAA Part 107 and sets SOPs for airspace, visual observers, weather minima, and maintenance. FAA — Small UAS Regulations (Part 107)

Spraying with drones adds another rulebook

When dispensing ag chemicals or seed by air, ag engineering addresses additional certification and operating requirements, coordinates with applicator rules, and documents training and maintenance to keep flights compliant. FAA — Dispensing Chemicals & Agricultural Products (Part 137)

Codes, permits, and “ag exemptions” vary by county

Even in areas with “ag exempt” provisions, ag engineering still coordinates zoning, utilities, fire, and electrical codes with local officials; early conversations remove surprises about setbacks, egress, sprinklers, and wiring. Colorado State University Extension — Building Codes & Permits

Career pathways that support your projects

Consulting firms, equipment manufacturers, conservation agencies, and research labs all hire for ag engineering roles focused on design, testing, field support, commissioning, and continuous improvement—career tracks that keep the work practical and close to outcomes.

Final thought

The quiet backbone of every productive farm is rigorous ag engineering: layouts that keep traffic safe, structures that stand through storms, machines and data systems that stretch every gallon of fuel and drop of water; treat it as a continuous improvement loop—measure, design, build, monitor, refine—and you’ll see it in uptime, yields, safety, and compliance.
