Drone spraying in Lafayette County covers big corn and soybean ground plus the hay and pasture that feed those herds.

The county land and water plan

Lafayette County's 2025–2036 land and water plan describes 52 streams covering 1,005 miles, with the Galena River and the Middle and Lower Pecatonica watersheds covering about three-quarters of the county. Agriculture makes up 85% of business sales and 54% of jobs, and cash rent for nonirrigated cropland, at $261 an acre, is the highest in Wisconsin. Dairy farms fell from 223 in 2017 to 146 in 2022, while average temperature has risen about 3°F and precipitation about 20% since 1950.

Thin soils and private wells

Much of the county has thin soils over fractured dolomite. In a 2022 study of private wells, 69% of samples tested positive for coliform bacteria and/or nitrate above 10 mg/L. Low-volume passes, careful timing before rain and mapped buffers around wells and sinkholes help keep products where they belong.

The Galena River watershed

The Galena River watershed covers 242 square miles of southwest Lafayette and southern Grant counties. The Wisconsin DNR names cropland and barnyard runoff and overgrazed stream banks as its main problems, and Bull Branch, Diggings Creek and Louisburg Creek are listed as impaired. About 35 abandoned mine sites and 125 mine-waste piles remain from the lead mining era. Operators map streams, banks and old mine ground as no-spray zones.

Yellowstone Lake

Yellowstone Lake, a 455-acre impoundment, is one of the largest lakes in the Driftless Area, with about 800 acres of state park and more than 4,000 acres of wildlife area. Its watershed is dominated by agriculture, and the county plan lists the Yellowstone River among the areas with the highest estimated soil loss. Fields draining toward the lake get wider buffers.

The Pecatonica at Darlington

The Pecatonica River nearly encircles Darlington in a horseshoe bend, and flooding there has grown more frequent since 1950. When bottom fields stay wet after high water, a drone can treat them without ruts.

Plain farms and tobacco

The Platteville–Darlington Amish settlement was founded in 1999 and now numbers about 1,620 people. Many families raise hand-harvested tobacco alongside dairy, and UW Extension Lafayette publishes pest articles in the Wisconsin Amish Shopper. Small tobacco, produce and hay fields sit next to larger grain farms, so operators map them as no-spray zones and neighbors can share a trip.

Pest traps and scouting

UW Extension Lafayette runs pheromone traps across southwest Wisconsin for black cutworm and true armyworm in spring, switching to western bean cutworm and fall armyworm later in the season, and offers crop scout training for corn, soybeans and alfalfa. Its on-farm trials have tested cereal rye covers with corn and corn silage. Trap counts and scouting decide when a drone pass makes sense.

Wisconsin licensing

The Wisconsin Department of Agriculture, Trade and Consumer Protection (DATCP) requires commercial drone applicators to hold an aerial certification on top of their base category, an individual license and a pesticide business license. Private applicators need certification for restricted-use pesticides applied by drone. The business holds an FAA Part 137 certificate, and pilots hold Part 107. Wisconsin takes part in DriftWatch and BeeCheck, and operators check the maps before every job.
