Corn that stays close to home

Cedar Rapids is one of the country's big corn processing centers. ADM's plant there grinds about 750,000 bushels a day across its wet and dry mills, more than 1,000 grain trucks come through daily, and Cargill runs another major plant. Protecting yield in the county's 153,000 acres of corn feeds straight into that demand.

Tar spot and fungicide timing in 2026

ISU plant pathologists put the fungicide window from VT through R3. Tar spot was reported in 10 Iowa counties by June 30, 2026; it favors about 30 days of 64–73°F weather, slows in midsummer and rises again in September. Gray leaf spot and northern corn leaf blight are the other targets, while southern rust risk in Iowa stays low. A drone treats tasseled corn without driving down rows.

The 2020 derecho

On August 10, 2020, a derecho crossed 57 Iowa counties, with severe crop damage in 36. The strongest gust, 112 mph, was measured at Midway in Linn County, and grain bins across the area were destroyed. Lodged and leaning corn after a storm is hard to reach with a ground rig; a drone flies over it.

Cedar River water and the Middle Cedar project

Cedar Rapids draws its drinking water from shallow wells along the Cedar River, and the city has partnered with farmers upstream for more than 20 years. The Middle Cedar Partnership Project, a priority watershed under the Iowa Nutrient Reduction Strategy, put more than 37,500 acres into practices over five years, and bioreactors and saturated buffers cut nitrate loads by about 42% and 32%. The project reached about 435 landowners in Benton, Tama and Black Hawk counties, with 17,382 cover crop acres under contract by 2018. After riverbank filtration, the water reaches two lime-softening plants. Drone-seeded cover crops go into standing corn and soybeans in late summer.

The 2008 flood

On June 13, 2008, the Cedar River crested at 31.12 feet in Cedar Rapids, more than 11 feet above the previous record, flooding about 14% of the city. Bottom fields along the Cedar and Wapsipinicon stay soft after high water, and a drone treats them without ruts.

Palisades-Kepler and the Wapsipinicon

Palisades-Kepler State Park, about 840 acres on the Cedar River near Mount Vernon, was created in 1922 and built out by the CCC. The Wapsipinicon River crosses the north of the county past Central City and Troy Mills. Parks, rivers and creeks are mapped as no-spray zones.

Eastern Iowa Airport airspace

The Eastern Iowa Airport's Class C airspace reaches the surface within five miles of the field and covers a wider ring above 2,100 feet out to ten miles. The airport covers 3,288 acres and served about 1.63 million passengers in 2025. Fields near the airport need FAA authorization before every flight, and crews plan those jobs ahead.
