First in Iowa for crop sales

Kossuth County, Iowa's largest county at about 974 square miles and home to 14,828 people in 2020, about 5,500 of them in Algona, ranked first in the state for crop sales in the 2022 Census of Agriculture and fifth for total sales, at $924.7 million.

Crop or livestock	2022
Corn for grain	304,340 acres
Soybeans	212,495 acres
Hogs	542,697 head
Cattle	21,456 head
Farms	1,342, averaging 436 acres

About 524,000 acres are harvested cropland, with corn on 880 farms and soybeans on 723. The county borders Martin and Faribault counties in Minnesota to the north. Crop spraying in Kossuth County is about covering a lot of corn and soybean acres in short summer windows.

What agronomists saw in July 2026

Iowa State's late-July 2026 update for this region found corn at R2 and soybeans at R2–R3, with growers calling about soybean aphids and fungicide timing. A July 20 storm dropped up to 2 inches of rain with hail and lodging in neighboring Hancock County, and southern rust was confirmed in four Iowa counties at low levels.

Soybean aphid threshold

The standard threshold is 250 aphids per plant on 80% of plants with populations rising, from R1 through R5. Scout about 30 plants per 50 acres. With aphids already driving agronomists' calls in this region by late July 2026, weekly scouting through August pays.

Iron deficiency chlorosis

Iron deficiency chlorosis yellows soybeans on high-pH soils above about 7.3, especially in cool, wet springs, and it's common on north-central Iowa's calcareous ground. The Iowa Soybean Association lists tolerant varieties, higher seeding rates and chelated iron at planting as the main tools, with some iron products also labeled for plants once symptoms show.

Wind turbines in the fields

Alliant Energy's Kossuth Wind Farm has run 56 turbines since 2020, and the Kossuth County Wind project near Lu Verne added 25 more in 2022. Landowners host them in crop fields and receive lease payments, and more projects have been proposed in the county's southeast. Operators map every tower and power line before flying and keep safe distances from moving blades.

Drainage districts and wet ground

Kossuth County has about 159 drainage districts, with the Board of Supervisors as trustee for nearly all of them, and district maps were redrawn in 2018. Tile and open ditches carry water off flat, poorly drained ground. When fields stay wet after rain, a drone treats them without ruts, and ditches are mapped as no-spray zones.

Union Slough National Wildlife Refuge

Union Slough National Wildlife Refuge covers 3,334 acres along seven miles of a pre-glacial riverbed near Bancroft that once linked Minnesota's Blue Earth River with the East Fork of the Des Moines River, in the prairie pothole region. Established in 1938, it has seen trumpeter swans reintroduced in 1996, its first bald eagle nest in 2012 and nesting sandhill cranes since 2019. The refuge and wetlands are mapped as no-spray zones, and DriftWatch and BeeCheck are checked before every job. The Iowa Wetland Management District, which oversees wetlands across the region, is based in Titonka.

Iowa licensing and airport

The Iowa Department of Agriculture and Land Stewardship (IDALS) certifies drone applicators through the aerial exams under an Iowa pesticide company license, and aircraft are registered with the Iowa DOT. Iowa's bee rule bars bee-toxic products on blooming crops within a mile of registered hives from 8 a.m. to 6 p.m. Algona Municipal Airport, two miles west of town with a 4,200-foot concrete runway and a turf strip, also hosts ag aviation, so crews check airspace nearby.
