Ag Drone Services in Knox County, NE

Ag drone service rates in Knox County, NE

Ag drone services in Knox County, NE are priced per acre, application only, by FAA Part 137-certified operators licensed by the Nebraska Department of Agriculture. These are typical one-pass rates for fields around Creighton, Bloomfield, Crofton, Wausa and Center.

Service	Typical rate
Corn fungicide (VT–R2)	from $14/acre
Western bean cutworm or rootworm beetle insecticide	from $14/acre
Soybean fungicide or aphid insecticide	from $13/acre
Alfalfa and hay insecticide	from $14/acre
Pasture weed and thistle control	from $15/acre
Cover crop seeding	from $17/acre

Product is billed separately or supplied by you. The minimum charge is $300 per visit. University of Nebraska–Lincoln's 2026 custom rate survey puts drone spraying at about $15 per acre on average, in a range of roughly $13–$20, so these rates sit at or slightly below the Nebraska norm. Steep bluff pastures, trees and long travel raise the per-acre price.

Knox County farms by the numbers

Measure	Knox County
Farms (2022 Census)	950
Land in farms	482,157 acres
Average farm size	508 acres
Farm sales	about $470 million
Hogs	about 120,000 head
Cattle and calves	about 117,000 head

Corn makes up about 43% of harvested cropland, soybeans about 32% and hay about 18%. Knox County ranks among Nebraska's top hog counties, and cattle are just as important. Agricultural drone services in Knox County therefore cover both row crop fungicide and insecticide passes and pasture and hay weed control on the rolling ground toward the Missouri River.

Corn: leaf diseases and western bean cutworm

Gray leaf spot and northern corn leaf blight are the usual targets of a fungicide at tassel in northeast Nebraska, and tar spot has spread across eastern Nebraska in recent seasons, so scouting from late July is worthwhile. Western bean cutworm is the key insect: University of Nebraska–Lincoln guidance suggests treatment when about 5–8% of plants have egg masses or small larvae, timed close to egg hatch. Corn rootworm beetles in continuous corn add another reason for a late-summer pass. Drones reach tall corn without knocking down rows and can treat irrigated and dryland fields on the same day.

Soybeans: white mold, frogeye and aphids

White mold is a risk in irrigated, high-yield soybeans when July and August are cool and wet, with fungicide timing around early bloom. Frogeye leaf spot and soybean aphids may also call for an R3 pass. University of Nebraska–Lincoln uses the standard threshold of about 250 aphids per plant with populations increasing. Drones avoid wheel tracks in narrow-row beans and keep the pass on schedule after rain.

The Bazile Groundwater Management Area

Parts of Knox County fall within the Bazile Groundwater Management Area, created because many wells in the area have nitrate levels above drinking water standards. Rules there limit fall and winter commercial nitrogen applications, require splitting larger nitrogen rates and call for annual reporting. Drones can help with in-season work, such as foliar products or cover crops seeded into standing corn and soybeans, that supports better nitrogen use. Operators keep application records that fit your reporting needs.

Pastures, thistles and eastern redcedar

Hilly pastures along the Missouri River bluffs and the Niobrara breaks are steadily invaded by eastern redcedar. Musk thistle, Canada thistle and leafy spurge are on Nebraska's noxious weed list, and landowners must control them. Drones spray thistle rosettes in spring and fall, treat leafy spurge in June and spot-treat small cedars before they grow too large for herbicides, all on slopes where a ground rig cannot go.

Fields around hog and cattle operations

Many Knox County fields receive manure from hog barns and feedlots. Manured ground often has heavier weed and disease pressure and stays soft longer after rain. Drones keep spray equipment off farm roads and away from barns, which also helps with biosecurity. Operators avoid barn air intakes and coordinate timing with livestock managers.

Lewis and Clark Lake, the Niobrara and the Santee Sioux Nation

Knox County borders Lewis and Clark Lake on the Missouri River and includes the lower Niobrara River and the Santee Sioux Reservation. Operators follow label buffers from water and map creeks, ponds and wetlands as no-spray zones. Pesticide rules on tribal land can differ from state rules, so operators confirm the requirements with the landowner and the tribe before working on reservation land. Nebraska is a FieldWatch state, and crews check the registry for nearby specialty crops and beehives.

Alfalfa and hay ground

Hay makes up nearly a fifth of Knox County's harvested cropland, much of it alfalfa grown for local cattle and dairies. Alfalfa weevil larvae are the main spring pest, and University of Nebraska–Lincoln suggests treating based on the percentage of tips showing feeding and the expected cutting date. Potato leafhoppers can stunt regrowth after first cutting, and grasshoppers move in from pasture edges in dry summers. A drone can treat a fresh-cut field without driving over regrowth and can work hillside fields where wheel traffic is risky.

Nebraska licensing for drone spraying

• FAA: Part 107 remote pilot certificate, Part 137 agricultural aircraft operator certificate and a Section 44807 exemption for drones over 55 lb.
• Nebraska Department of Agriculture: a commercial pesticide applicator license with the General Standards exam and the Aerial category, which covers drone application.
• Records: application records for every job, available to the landowner.

Ask for the operator's NDA license number before booking.
