Ag Drone Services in Sioux County, Iowa for Corn and Soybeans

Ag drone services pricing in Sioux County

Ag drone services in Sioux County, IA are priced per acre for one pass, application only. Sioux County sold $2.34 billion in farm products in 2022, the most of any county in Iowa and 12th in the nation. Livestock brings in 81% of that total, but corn, soybeans and silage still cover more than 426,000 acres. The rates below are built for manure-fed corn and soybean ground around Sioux Center, Orange City, Rock Valley and Hull.

Service	Typical rate	Notes
Corn and soybean herbicide	from $11/acre	Post-emerge, 2–3 gallons per acre
Corn fungicide	from $12/acre	Grain and silage corn, VT–R2
Soybean fungicide or insecticide	from $12/acre	R3 timing, closed rows
Corn insecticide	from $12/acre	Western bean cutworm, late season
Cover crop seeding	from $13/acre	Rye after silage or into standing crops

Product is billed separately, or the farmer supplies it. Iowa drone rates run about $8–18 per acre, with $12.50 typical for 2026, and local listings start at $12. Our rates sit under the typical figure. The quote depends on water volume, crop height, field shape, livestock buildings, power lines and travel distance. The minimum charge is $300 per visit.

Net cash farm income reached $622.4 million in 2022, up 66% from 2017. Almost every field in Sioux County sits within sight of a hog barn, feedlot or dairy.

Ag drone services around barns and feedlots

With 1.46 million hogs and nearly 382,000 cattle, livestock sites are everywhere. That shapes every spray job:

• hog barns, feedlots, dairies and lagoons are mapped as no-spray zones;
• wind direction keeps spray away from barn fans and open-sided cattle buildings;
• operators clean equipment and stay off farm pads unless the owner clears it;
• fields near rural homes and acreages get coarse droplets on the edge passes.

A drone handles irregular fields cut by building sites and feed alleys more easily than a large boom. It also avoids extra wheel traffic on fields that already carry manure tankers and silage trucks every year, which helps limit compaction on the county's heavy-use ground. Many livestock farms are also short on labor in summer, and booking a drone pass frees up a person and a tractor for chores and hay.

Silage corn and grain corn disease

Sioux County grows about 40,700 acres of corn for silage, mostly for dairies and feedlots. Leaf disease cuts silage quality as well as grain yield. Gray leaf spot and northern corn leaf blight are common, and tar spot has reached every county in Iowa since 2021. Fungicide returns are most consistent from VT to R2, when corn is too tall to cross without damage. Western bean cutworm egg masses are scouted in July, and treatment is timed before larvae enter the ears.

Soybeans: aphids, white mold and waterhemp

• Soybean aphid: treated only above the Extension threshold, usually in July and August.
• White mold and frogeye leaf spot: scouted from R1, with an R3 fungicide as the usual pass.
• Waterhemp: resistant to several herbicide groups across northwest Iowa. Post passes need small weeds.
• Dicamba: the 2026 over-the-top dicamba labels don't allow aerial application, so drone programs use other labeled post products.

Cover crops after silage harvest

Silage harvest leaves bare, manure-fed ground in September on many Sioux County farms. Cereal rye flown on right after chopping, or into standing corn before harvest, takes up leftover nitrogen and holds soil through winter. Some farms graze or cut the rye in spring. A drone covers the seeding with no tractor trips on soft fall ground and no conflict with manure application schedules.

Rock, Floyd and Big Sioux watersheds

The west side of Sioux County drains to the Rock and Big Sioux rivers, and the east side drains to the Floyd River. With so much manure applied, nitrate and bacteria in these streams are long-running concerns. Operators map streams, tile intakes, wells and sinkholes as no-spray edges, use coarse droplets near water, and keep rates accurate. Iowa rules also limit some applications near bee yards during the day, so operators check registered hives before every job.

Local airspace

Sioux County Regional Airport, between Orange City and Sioux Center, has no control tower, but aerial applicators use it all season. Sioux Falls Regional Airport has Class C airspace about 45 miles north, and Sioux City is to the south. Most Sioux County fields sit in uncontrolled airspace, and operators still check traffic and flight restrictions before every job. During peak season, manned spray planes work the same fields, so operators coordinate times with neighbors who have booked aerial work.

Iowa licensing for drone applicators

For-hire drone applicators in Iowa need a commercial applicator certification from the Iowa Department of Agriculture and Land Stewardship, including the aerial category and a crop category, plus a company license. FAA requirements are Part 107, a Part 137 certificate, and a Section 44807 exemption for drones over 55 pounds.
