Soybeans, hay and cattle

Corn for grain	29,940 acres

Cattle and calves	48,947 head

Cattle numbers ranked 29th in Missouri, crops 35th and total sales 50th, and the county also carries about 2,000 sheep. Fewer than 750 acres are irrigated, so ag drone spraying in Linn County works dryland soybeans and corn plus a large hay and pasture base.

MU's northern research center

MU's Northern Missouri Research, Extension and Education Center near Linneus covers three properties totaling about 4,190 acres focused on grazing systems, from cow-calf to stocker and finishing. Its 1,200-acre Cornett Farm, leased from 1965 and donated in 1981, studies forage-beef systems and cool-season grasses. An MU agronomy field specialist based in the Linneus courthouse covers crop diseases, insects, weeds and forages across 11 north Missouri counties.

Locust Creek and Pershing State Park

Locust Creek enters the county west of Browning and flows past Purdin, Linneus and Laclede to the Grand River. The 330-acre Locust Creek Natural Area protects an unchannelized stretch, rare in north Missouri, with bur oak, pin oak and pecan bottoms; upstream, the creek is channelized for miles, which adds flooding and sediment downstream. Pershing State Park, about 5,362 acres west of Laclede, holds nearly 1,000 acres of wet prairie, the largest left in north Missouri. Operators map the creek, the park and wetlands as no-spray zones and fly only with wind blowing away from them.

Swan Lake and wildlife next door

Just south in Chariton County, Swan Lake National Wildlife Refuge covers 10,795 acres, set up in 1937, where wintering Canada geese once topped 200,000. Fields draining toward the refuge and the Grand River get wider buffers and flights only in calm, steady wind.

Pershing, the covered bridge and the railroad

General John J. Pershing grew up in Laclede. The Locust Creek Covered Bridge, built in 1868 and 151 feet long, is the longest of Missouri's four remaining covered bridges and now stands in Pershing State Park near Meadville. Brookfield, home to 4,111 people in 2020, grew on the Hannibal and St. Joseph, the first railroad across Missouri, finished in 1859, and Walt Disney spent part of his boyhood near Marceline. US 36, the planned route of a future I-72, ties the towns together and carries grain and cattle trucks across the county. Farm fields along the highway and rail lines are mapped around power lines and crossings before every flight.

Licensing and airspace

The county covers 621 square miles and had 11,874 residents in 2020.
