Who supplies the product?

You can supply it from your co-op or retailer, or the operator can source it and bill it separately.

What wind speed stops a flight?

Most labels and operators stop around 10 mph. Mornings in the river valleys are usually calmest.

How soon after rain can you fly?

Usually the same day, once leaves are dry enough for the product to stick.

Can you spray a 10-acre hay field?

Yes. Small fields are billed at the 15-acre minimum, and neighbors can share a trip.

Do I need to be at the field?

Someone should review boundaries before the first flight. After that the crew works on its own.

What records do I get?

An application record with the date, product, rate, acres, weather and a flight map, useful for nutrient plan paperwork.

They seeded rye into our standing beans in September, and it was up before we combined.

Our hillside hay field is too steep for the sprayer, and the drone covered every foot of it.

A livestock county

Knox County had 1,303 farms in the 2022 Census of Agriculture, and sales rose 79% to $241.2 million, 61% from livestock.

Crop or livestock	2022
Soybeans	48,674 acres
Corn for grain	45,347 acres
Hay and haylage	17,907 acres
Broilers	1.59 million
Hogs	34,726 head
Sheep	7,409 head

The county ranks third in Ohio for sheep, goats and wool, and ninth for both poultry and hogs. Farmland covers about 58% of the county and forest about 28%, and the county had 62,721 residents in 2020, about 17,000 of them in Mount Vernon. With 47% of farms under 50 acres, ag drone services in Knox County cover pasture and hay as much as corn and soybeans.

Sheep country pastures

A 2022 statewide sheep tour called Knox a prime sheep-producing area, visiting a 160-ewe flock near Howard and a Danville feedlot that finishes several thousand lambs. Clean pasture matters for those flocks. Grazing intervals on many pasture herbicides differ for sheep, goats and cattle, so the label for each animal decides the product and when flocks can return.

The Kokosing State Scenic River

The Kokosing was designated a State Scenic River in 1997, covering 41 miles of the main stem and 6.5 miles of the North Fork. Its 482-square-mile watershed holds one of Ohio's most diverse fish communities, including the state-endangered spotted darter, before it joins the Mohican through a sandstone gorge. The Owl Creek Conservancy works across the Kokosing, Mohican, Wakatomika, Rocky Fork and North Fork Licking watersheds to preserve natural and farm land. Operators map the river, tributaries and drainage ways as no-spray zones and use only products labeled for use near water.

H2Ohio nutrient plans

H2Ohio expanded statewide in April 2024, and Knox County farmers enrolled about 16,000 acres in voluntary nutrient management plans at $10 per acre, with the county's soil and water district writing dozens of plans. Plans call for the right rate in the right place, which a drone can deliver with variable-rate fertilizer or in-season passes without driving on wet ground.

Plain communities and small fields

The Danville–Brinkhaven Amish settlement dates to 1990 and the Fredericktown settlement, shared with Morrow County, to 1973; about six settlements lie fully or partly in Knox. Small hay fields, pastures and produce plots sit next to larger grain farms, and buggies share every county road. Neighbors can group fields into one trip to spread the minimum.

The Gap Trail and conserved land

The 14-mile Kokosing Gap Trail runs through farmland from Mount Vernon to Gambier, Howard and Danville. Near Gambier, Kenyon College's Brown Family Environmental Center protects 700 acres, and the Philander Chase Conservancy has conserved almost 5,700 acres within five miles of the college, including farmland easements. Operators map trails, preserves and homes as no-spray zones and check DriftWatch and BeeCheck before every job.

Drone cover crop research at Ohio State

Ohio State engineers John Fulton and Alex Thomas have run drone cover crop seeding trials through OSU's eFields program, testing how seed flown into standing crops establishes. Drones seed cereal rye or mixes into soybeans and corn in late summer, so the cover is up before harvest.

Field conditions

Field condition	Ground sprayer	Spray drone
Rolling hills and slopes	Rollover risk	Follows terrain
River bottoms after rain	Ruts, compaction	No soil contact
Corn at tassel	Crop damage	Flies above the canopy
Small fields between woods	Missed corners	Mapped edges

A Knox County spray season

Window	Typical drone work
April to May	Pasture broadleaf weeds
June	Hay weed passes between cuttings
Late July to August	Corn fungicide at tassel, soybean R3 passes
Late August to September	Cover crops into standing crops
Fall	Fertilizer on nutrient-plan fields

Ohio licensing and airspace

The Ohio Department of Agriculture (ODA) licenses commercial drone applicators under its aerial category plus Core, and the business operates under an FAA Part 137 certificate with Part 107 pilots. Knox County Airport sits southwest of Mount Vernon with a 5,504-foot runway, and Columbus lies about 40 miles southwest, so crews check airspace for fields nearby.

Frequently asked questions

Yes, during the flight. Labels set return times, and some differ for sheep, goats and lactating animals.
