Drone Spraying in Richland County, WI for Dairy Forage and Corn

Richland County drone spraying rates

Drone spraying in Richland County, WI is priced per acre for one pass, application only. Livestock brings in two-thirds of farm sales here, and hay and haylage cover nearly 40,000 acres, more than corn. Rates are set for steep Driftless fields farmed in contour strips, where alfalfa, corn and soybeans often share one hillside.

Service	Typical rate	Notes
Alfalfa insecticide	from $14/acre	Weevil and leafhopper, strip by strip
Corn and soybean herbicide	from $14/acre	Post-emerge, 2–3 gallons per acre
Corn fungicide	from $15/acre	Tassel timing, R1–R3
Soybean white mold fungicide	from $15/acre	Beginning flower to beginning pod
Cover crop seeding	from $15/acre	After silage or into standing crops

Product is billed separately, or the farmer supplies it. Wisconsin drone rates run about $11–22 per acre, with $16 typical for 2026, and regional operators publish tiers of $16–18 with a $400 minimum. Our rates sit just under the typical figure. The quote depends on water volume, slope, strip layout, woodlots and power lines, and travel distance. Few operators are based in this corner of the state, so jobs are often grouped. There is a 20-acre billing minimum per visit.

Richland County dairy and forage numbers

Measure	Richland County, WI (2022 Census)
Farms / land in farms	1,062 farms / 244,767 acres
Average farm size	230 acres
Market value of sales	$183.0M, 41st in Wisconsin, up 34%
Livestock share	67%
Milk sales	$86.95M
Cattle and calves	48,631 head
Hay and haylage / corn for grain	39,597 / 37,546 acres
Soybeans / corn silage	18,196 / 8,384 acres

Directory pages show 22,362 acres of alfalfa and hay, but the full forage figure is nearly 40,000 acres. On most farms here, the spray calendar follows the cutting schedule. Amish settlements around Hillsboro and Readstown reach into the county, and 3% of farms are certified organic, so drift planning matters.

Drone spraying Richland County contour strips

Richland County sits in the unglaciated Driftless Area, the rugged hills once called the Ocooch Mountains. Fields climb out of narrow valleys and are often farmed in contour strips, with corn, alfalfa and small grain side by side.

• Strip-by-strip control: a mapped drone flight sprays only the strips that match the product in the tank, and shuts off over the alfalfa next door.
• Steep side-hills: no rollover risk and no tracks across slopes that took years of erosion work to stabilize.
• Small, odd fields: valley-floor fields wrapped around woods and streams are finished edge to edge.
• Low height: 8–15 feet above the canopy, which matters near trout water and farmsteads.

UW Machinery Extension notes that drones cover roughly 20–40 acres an hour and work best on small or irregular fields near trees. It also warns that raising the mix concentration to cover more acres per tank is off-label for those products.

Alfalfa weevil and leafhopper on hillside hay

UW Extension advises starting weevil scouting at 300 growing degree days (base 48°F), beginning on south-facing slopes, which Richland County has plenty of. The threshold for first crop is 40% of stems with feeding when harvest is more than a week away, and 50% on regrowth. Potato leafhopper thresholds rise with plant height, so newly cut regrowth is the most vulnerable stage. A drone treats only the alfalfa strips on a hillside, without crossing corn or tracking new growth.

Tar spot and white mold timing

UW's 2026 mid-season update found no tar spot yet in southern Wisconsin fields with a history of the disease, but rated the risk high. The key spray window runs from tassel (R1) to R3, with a single pass at tassel as the most important timing, using two modes of action.

For white mold in soybeans, UW recommends spraying between beginning flower and beginning pod, with the canopy about 40% closed. Endura at R3 remains a standard choice, and there's no yield response at R5. Both windows come when corn is over 8 feet tall and soybeans are closing rows, which is the job drones were built for.

Class I trout streams and spring-fed creeks

Richland County's spring-fed streams are a big part of its identity. In 2020, the Wisconsin DNR proposed Class I trout status for eight Richland streams totaling about 37 miles, including 14 miles of Mill Creek and parts of Dieter, Wheat, Ryan, Coulter and Hood hollows. Willow Creek, which joins the Pine River, is managed with the goal of reaching Class I. The county credits decades of erosion work for cutting sediment and improving trout fishing. Richland County fields along these valleys are flown with label setbacks, coarse droplets, and wind direction away from the water.

Kickapoo floods and the Lower Wisconsin Riverway

Flash floods are part of farming here. In August 2007, 7–13 inches of rain caused about $10 million in damage. In June 2008, the Kickapoo River at Viola crested at a record 21.25 feet. The Pine River runs through Richland Center behind a flood-control project. On the south edge, the Lower Wisconsin State Riverway runs 92 miles from Prairie du Sac to the Mississippi, past Lone Rock. Bottom fields along the Kickapoo, Pine and Wisconsin rivers can stay soft for days after storms. A drone keeps the spray on schedule without rutting them.

Airports near Richland Center and Lone Rock

Richland Airport, about 4 miles southeast of Richland Center, is unattended and has a 3,200-foot paved runway. Tri-County Regional Airport near Lone Rock is jointly owned by Sauk, Iowa and Richland counties, with a 5,000-foot runway. Neither has a control tower. Operators still watch for local traffic and crop-spraying aircraft near both.

DATCP licensing and label rules

Under DATCP's drone guidance, a for-hire operator needs FAA Part 107 and Part 137 credentials, plus a Section 44807 exemption for drones over 55 pounds. They also need DATCP certification in a base category such as 1.1 plus aerial category 9.9, an annual Individual Commercial Applicator License, and a Pesticide Business License. Farmers using restricted-use products by drone on their own land need private certification with aerial category 111.0. Products whose labels prohibit aerial application can't be applied by drone, and that includes 2026 over-the-top dicamba. Wisconsin's FieldWatch registry lists organic fields and apiaries, and operators check it before every job.
