Drones for Crop Scouting

What can a drone show about a crop?

From above, patterns appear that you cannot see at ground level: uneven stands, wet or dry patches, lodged plants, wheel tracks, drainage lines and areas where wildlife has been feeding. A quick flight can cover a large field in a short time and show which spots need a closer walk.

Some drones carry special cameras that record light beyond what the eye sees. Those images can highlight plant stress but must be interpreted carefully. Different crops need different timing. A flight early in the season can show gaps in emergence, while one later may reveal lodging or disease patterns. Ask an advisor what to look for at each stage. Wet spots seen early can guide where to dig a test hole, and tracks across a field can show where deer or livestock are getting in.

• Uneven stands and gaps
• Water damage and standing water
• Wind or hail damage
• Wildlife feeding patterns

What can a drone not tell me?

A picture cannot tell you the cause of a problem. A yellow patch might be disease, insects, nutrient shortage, herbicide drift, compaction or something else. Without going to the spot, digging, counting and sometimes testing, you may treat the wrong thing.

Extension specialists and crop advisors can help you match what you see to a cause. Many offer help for sample submissions, and some labs accept samples for testing.

How should I plan a scouting flight?

Fly at a consistent time of day, ideally with similar light each time, so images are comparable. Choose calm weather. Keep the same height and path from flight to flight if you want to see change over time. Note the date, growth stage and weather with each flight.

Mark places that look unusual with a phone's GPS, then walk to each one. Take photos of what you find at ground level to match the aerial image.

Keep to rules about flying height, distance and visual contact, and check the latest requirements. Share your plan with whoever sprays or works nearby, so you do not meet spray equipment or low aircraft while flying. Avoid launching near power lines, irrigation pivots and tall equipment.

What about the rules, privacy and neighbors?

Scouting flights fall under the aviation authority's rules and may count as business use. Check current requirements, including registration, training and where flying is restricted. Our article on drone rules points to the right places.

Fly only over land you own or have permission to use. Never drift over a neighbor's field or home. Tell neighbors and be mindful of livestock, which may be easily frightened. Do not fly near people applying chemicals or near aircraft that do. Check whether any program or crop insurance you use accepts images as evidence, and ask the agency or your agent, since rules differ.

How do I use the images afterward?

Store images with dates and field names. Compare them over several weeks and across seasons. A problem that appears in the same place year after year may point to drainage, compaction or soil differences, and records help you explain it to an advisor.

Software that stitches images into maps can help, but simple side-by-side comparisons work well on small farms. Use free tools first and learn what you need before paying for more.

Share images with an extension agent or crop advisor if you need help interpreting them. Keep file names consistent, such as field name and date, so you can find them a year later.

Is a drone worth it for a small farm?

For a small place, walking may be faster and cheaper than learning and maintaining a drone. A drone becomes more useful as acreage grows, as fields get hard to walk, or after a storm when you need a quick look at damage.

Compare the real cost, including batteries, time to learn, storage and rule compliance, against the value of the information. Ask a neighbor or extension office whether a shared service or hired operator makes more sense, and check the rules for paid services. Weigh time too. Learning to fly, process images and interpret them takes hours that may be better spent walking, depending on the size of your operation. A shared flight with a neighbor, or a hired operator, can spread the cost across several farms, as long as the person flying follows the rules.
